Sewer Jetting Equipment

For technical and sanitary reasons, sewer jetting machines are frequently cleaned. Particularly, the blocking of the cross sections as well as odour problems need to be avoided. Also, damages at the channel walls must be recognized very early, which is only possible, if the walls are completely clean. Further, inorganic deposits that reduce the sewage treatment efficiency must be removed.

Sewer jetting / drain jetting / gutter cleaning is the process of using sewer jetting machines to bring a sewer drain line back to like-new condition without having to actually replace the line. This is very cost-effective practice, as well as a nearly effortless task- especially for drain jetting that are heavily used, even for grease. (You aren’t supposed to be dumping that down there in the first place!).

Anyone, who has ever had to deal with a sewer or even residential septic tank, knows all about clogs and back-ups. Soap scum residue, grease, hair, food, mineral deposits and more can all cause a drain to back up. As much as people try to be careful with what they send down the tube, it is almost inevitable that these things will at some time pass through eventually causing clogs. Even as careful as you are with grease- you may not directly dump it down the drain- but the remaining grease on pots, pans and plates can cause a film that over the years can build up and solidify. Sometimes a simple unclogging could do but after masses of build-up and too frequent blockages, perhaps a good sewerjetters would be a more effective method that will also last plenty longer.

Pressure Jet’s high pressure drain jetters equipments, drain jetting are completely suitable to achieve all above cleaning results, because these pumps are rugged in construction, have medium speed and perform to the entire satisfaction of the customer.

There are special drain jetting machines , designed specifically for this purpose, called sewer jetters. They can clean the pipes leading from sinks and bathtubs leading to the tanks, even those at long distances, which is especially helpful in the case of industrial piping. The sewerjetters work at a high pressure, between 150-300 bar and 12-400 lpm. The pressure can be adjusted throughout the job as needed. These sewer jetting machines use a special nozzle that gets down into the drains to loosen and cuts the clogged materials that are obstructing the pathways. This essentially scours the pipes clean and then washes the debris back up to be removed, usually through a vacuum pump.

Plunger Pumps

Piston pumps and plunger pumps are reciprocating pumps that use a plunger or piston to move media through a cylindrical chamber. The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive. Piston pumps and plunger pumps are also called well service pumps, high pressure pumps, or high viscosity pumps.

Piston pumps and plunger pumps use a cylindrical mechanism to create a reciprocating motion along an axis, which then builds pressure in a cylinder or working barrel to force gas or fluid through the pump. The pressure in the chamber actuates the valves at both the suction and discharge points. Plunger pumps are used in applications that could range from 70 to 2070 bars. Piston pumps are used in lower pressure applications. The volume of the fluid discharged is equal to the area of the plunger or piston, multiplied by its stroke length. The overall capacity of the piston pumps and plunger pumps can be calculated with the area of the piston or plunger, the stroke length, the number of pistons or plungers and the speed of the drive. The power needed from the drive is proportional to the capacity of the pump.

Seals are an integral part of piston pumps and plunger pumps to separate the power fluid from the media that is being pumped. A stuffing box or packing is used to seal the joint between the vessel where the media is transferred and the plunger or piston. A stuffing box may be composed of bushings, packing or seal rings, and a gland.

Piston pumps and plunger pumps have a number of components that require the choice of materials based upon wear considerations and contact with the media type. Components may have a number of materials used including bronze, brass, steel, stainless steel, iron, nickel alloy, or other material. For example, piston pumps that function in general service or oil service applications may have an iron cylinder and piston with a steel piston rod. The plunger, discharge valves, and suction valves come in contact with the media type transferred; material choices should be considered based on the fluid transferred. In power applications where continuous duty piston pumps and plunger pumps are needed, solid ceramic plungers may be used when in contact with water and oil, but may not be the appropriate choice for use with highly acidic media types.

The difference between piston pumps and plunger pumps as compared to rotary piston pumps is the actual mechanism used to transfer the fluid. The piston elements moving along an axis are called axial piston pumps. Rotary piston pumps typically have an internal rotating mechanism that moves the piston.

Plunger Pump Heads up to 7.250 psig Plunger pump heads are preferably used for simple, non-critical fluids. For critical, abrasive, toxic or flammable fluids diaphragm pump heads are recommended.

General Pump For Power Washer Equipment

Pressure washers have two main components – the engine and the pump. The high-pressure pump is the core of the system and a good quality pump, such as a General Pump, will last for years with minimal maintenance.Any pump that puts out pressure over 150 PSI (pounds per square inch) is considered a high-pressure pump. The most common high-pressure pump is the positive displacement reciprocating plunger pump / piston pump. General pumps are of this design, using solid ceramic plungers. General Pumps come in two basic designs. For medium to heavy home use, the most popular is the GPEZ series 44 with a triplex plunger pump and direct-drive system. They start at about $300.00. The General Pumps GPT series 47 solid shaft pump series 66 is a high flow triplex pump for belt-driven equipment.

This General Pump is preferred in pressure washer applications and start at about $500.There are duplex and triplex plunger pumps, but the triplex creates a smoother flow and is used most often with today’s pressure washers. Axial pumps are sometimes found on cheaper consumer models of pressure washers, and serve the purpose for homeowners who only use them occasionally, but they are usually just thrown away and replaced when broken. If you plan to keep and use your pressure washer regularly, you are better off with the triplex, ceramic plunger models such as the General Pump Series 66 high flow triplex pump.Positive displacement pumps work with the positive displacement of fluid and fixed volume.

The fluid is mechanically pushed through the channels on a regular cycle. The pressure and volume remain constant. Pressure is created when this flow is pushed through the restrictive nozzle orifice. The size of the nozzle orifice is chosen for the desired pressure at the desired flow. If you notice a decrease in pressure, check the nozzle for wear before thinking the pump is failing. High-pressure pumps today, such as General Pumps, are very robust and when properly maintained, can be virtually trouble free.What size pump do you need? Pressure washer power is calculated by multiplying the pressure per square inch (PSI) by the Gallons per minute (GPM). The easiest way to determine the right pump size for your engine is to multiply the engine horsepower by 1100.

This gives the cleaning units (CU’s) that your engine is made to deliver. (Cleaning units are figured by multiplying GPM x PSI.)To keep your General Pump in top shape for years to come there are some things you should be careful to do. You should change the oil every 3 to 5 months or after 500 hours of use. This schedule should be maintained AFTER the initial oil change, which should be done after the first 50 hours of break-in.You should always flush your General Pump with clean water after each use and use an environmentally friendly anti-freeze. Never store your General Pump with water left in it, and be careful to check the manufacture recommendations when using strong chemicals in the pump.

General Pump has been in the high-pressure pump business for over 30 years. They use forged brass manifolds, guaranteed for life. General Pumps have oversize connecting rods and wear resistant solid ceramic plungers with continuous lubricating packing.

Hydro Test of Boilers

The equipment should have been hydrostatically tested to a minimum of 1½ times the design pressure, in the factory, and copies of the manufacturer’s data report, signed by the authorized inspector witnessing and evidencing the test forwarded to all jurisdictional bodies as well as to the client.

However, the complete system, along with all interconnecting piping, should be hydrostatically tested before start-up to comply with code requirements and to check for leaks that may have occurred during shipping and handling. This test should be completed under the supervision of and witnessed by an authorized inspector who should represent the state or municipality having jurisdiction or the insurance company covering the installation.

At the option of this inspector, the hydrostatic pressure test may be at 1½ times the design pressure of the equipment, or at a pressure slightly less than the setting of the lowest safety valve. The latter test will avoid the necessity of blanking or gagging of safety valves, removing piping and plugging various pipe openings, removing controls and gage glasses, etc

The boiler and process lines must be completely vented in order to fill them with water. The following is a recommended procedure for hydrostatic testing:

1. Open the steam drum vent valve and gag the safety valves in accordance with safety valve manufacturer’s recommendations. In lieu of gagging, the safety valves may be removed and replaced with test plugs or blind flanges.

2. Open the vents on the interconnecting piping. Close steam outlet valve.

3. Isolate pressure switches, gauge glasses or control components that are not intended to be subjected to a hydrostatic test.

4. Fill the system with treated water in accordance with recommendations from the clients water treatment consultant. (Refer to section entitled “Water treatment Considerations”. The test water temperature range must be 70°F minimum to 120°F maximum (100°F to 120°F  water temperature is preferred). Care should be taken so that all air is vented while the equipment is being filled. Fill the equipment until  water overflows the vent, then close the vent.

5. Apply pressure slowly. The recommended rate of pressure increase is less than 3.4 bar (50 psi) per minute. Proper control must be  maintained so that pressure does not exceed the desired setting of the local steam boiler inspecting agency. Do not subject any pressure  part to more than 1½ times the design pressure rating of any component.

6. When the proper test pressure is reached, inspection in accordance with the test objective can begin. Examine the system for any leaks. If  no leaks are visible, hold the system in a pressurized static condition for a period long enough to satisfy the code requirement.

7. Upon completion of the test, release pressure slowly through a small drain valve. Then fully open vents and drains when the pressure  drops to 20 psig. Particular Care must be given to make sure that parts not normally containing water during Operations are drained free of water. The system should  be drained fully after hydrostatic testing, to prevent freezing, if the unit is installed in a cold weather area, and to minimize corrosion of  the metal surfaces.

8. If temporary handhole or manway gaskets were used for the test, they should be replaced with regular service gaskets before readying  the unit for operation.

Gaskets should never be reused. Replace gage glass if necessary and make sure that the gage cocks are open. Remove all blanks or gags  from safety valves andinstall relief valves, if removed.

9. Additional inspection at this time by the Authorized inspector will determine whether the installation including piping arrangements, valve gauges and controls and other equipment on the unit meets code and/or other jurisdictional requirements.

10. Refer to the “Summary of valve positions” for recommended positioning of the various valves during hydrostatic testing, from operation  manual of respective company.

What Is A High Pressure Pump And What Are Its Uses?

A high pressure pump is broadly defined as any pump that can generate high discharge pressure, generally in excess of 800 psi. Pumps that generate pressures between 800 and 3000 psi are known as moderate high pressure pumps, while pumps that generate anywhere between 3000 psi and 5000 psi are known as very high pressure pumps. Apart from these pressure levels, there is another category of pressure pumps known as ultra high pressure pumps that generate pressures significantly in excess of 5000 psi, in the range of 10,000 psi to 40,000 psi.

Common types of pumps used for high pressure applications are reciprocating positive displacement pumps, particularly plunger pumps, which are capable of handling high pressure applications easily. Though in many cases pistons are also used with high pressure pumps, they are usually used only for applications that require working pressures below 1000 psi. One common type of positive displacement pump used for high pressure applications is the triplex plunger pump. Triplex plunger pumps consist of three plungers driven by a single prime mover. The parallel use of three plungers gives the triplex pump a discharge for every 120 degrees rotation of the prime mover. Another similar type of reciprocating pump that performs high pressure pumping duties is the quintuplex plunger pump, which is, as the name suggests, a pump with four plungers driven by a single prime mover. Quintuplex plunger pumps and triplex pumps are commonly known as power pumps and generally found in high-pressure applications.

A device that has found widespread adoption in high pressure applications is the hydraulically driven intensifier or amplifier. These devices use hydraulic pressure to significantly increase the pressure of the fluid being pumped. The intensifier consists of a common rod connecting two pistons with different bore sizes. When hydraulic fluid acts on the larger piston, it causes the smaller piston to be moved. Depending on the direction in which the smaller piston is moved by the hydraulic piston, it either takes suction or pressurizes and discharges the working fluid at very high pressure. There are two types of intensifiers and based on their construction and working, they are termed single shot intensifiers and reciprocating intensifiers. A single shot intensifier consists of one large hydraulic actuator piston and a single, smaller, high pressure piston – both connected by a common piston rod. When the large piston is moved, it makes the smaller piston move and fluid discharge takes place. When the larger piston is returned to its original position, by a spring or air-retraction, the smaller piston moves back, taking in the suction.

On the other hand, for reciprocating intensifiers, there is one large hydraulic piston mounted in the center of a piston rod with two smaller high pressure pistons on either end of the rod. When the pressurized hydraulic fluid acts on one side of the large piston and moves it, one of the smaller pistons takes suction from the low pressure line, while the other smaller piston simultaneously pressurizes the fluid in its bore and discharges it at high pressure. Alternately, when the hydraulic pressure acts on the opposite side of the larger piston, the smaller piston, which was taking suction, pressurizes the fluid and discharges it, and the smaller piston that was discharging, takes the suction.

These high pressure pumps have found uses in a variety of high-pressure applications, with reciprocating pumps such as triplex pumps, commonly being used in high pressure applications such as water pumps for water jet cutting systems plus water jet cleaning systems. Some other applications where high pressure pumps are used include foam firefighting, reverse osmosis desalination, as well as pumping of liquid CO2 and high vapor liquids.
