Hydraulic Pressure Pump

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.

Hydraulic RAM $70.1 High Quality Content by WIKIPEDIA articles A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It functions as a hydraulic transformer that takes in water at one hydraulic head (pressure) and flowrate, and outputs water at a higher hydraulichead and lower flowrate. The device utilizes the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of lowhead hydropower, and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of water.

SIMRAD 21118237 RPU160 Reversible Pump Drive Unit Hydraulic Steering Systems $1300.37 RPU160 Drive UnitHydraulic steering systems are now being used in every category of small vessel. In many respects hydraulic steering is preferable to mechanical steering. Hydraulic systems normally comprise of two main components a steering wheel pump and steering cylinder(s). The steering wheel pump may be either a gear pump or a plunger pump. Which ever type is installed steering is achieved by turning the steering wheel in either direction causing oil from the wheel pump to be supplied to the appropriate side of the cylinder. Oil is returned via the opposite side of the cylinder back to the pump.The linear motion of the cylinder rod is transformed to a rotary motion by the tiller which turns the rudder shaft and rudder. Check valves (nonreturn valves) are usually incorporated to prevent the rudder driving the steering wheel pump. If an autopilot is to be included in such a hydraulic steering system then the oil flow providing the rudder movement must be controlled by electrical signals from the autopilot. The maximum flow rate of RPU160 is 1.6 l/min respectively measured at a pressure of 10 bar with nominal voltage (12vdc) on the motor terminals.

Aquatec ERP1000 Permeate Pump $109.34 No electricity required powered only by hydraulic energy normally lost to drain. Improves water quality by insuring membrane efficiency. Improves membrane life prevents TDS creep . Increases product tank pressure (up to 95 of feed pressure). For all membranes rated 10 120 GPD. Effective for inlet water pressures as low as 30 PSI. Compact size for easy installation. Powered by hydraulic energy from brine water usually lost to the drain (i.e. no electricity required) the Permeate Pump pushes more purified water into the storage tank reducing membrane back pressure therefore maximizing available feed pressure. This pump dramatically improves the membranes production reducing wastewater by 80 or more. Basically if an R.O. system requires 10 Gallons of tap water to produce 1 Gallon of pure water (10: 1) the Permeate Pump should reduce this ratio below 3: 1. Permeate Pumps can also bring storage tanks up to line pressure then shut the system down when the tank reaches capacity removing the need for a hydraulic shutoff valve. Permeate pumps also deliver faster R.O. water production higher delivery pressures superior water quality and extended filter/membrane capacity.

Pump $66.91 High Quality Content by WIKIPEDIA articles A pump is a device used to move fluids, such as liquids or slurries, or gases. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure; they only displace fluid, causing a flow. Adding resistance to flow causes pressure. Pumps fall into five major groups: direct lift, displacement, velocity, buoyancy and gravity pumps. Their names describe the method for moving a fluid.
