Not only is this pump variable, but it can be inverted, by making sure the direction and speed of the motor gyration are guarded from inside the pump on the output of a transmission pump. It will get rid of the directional or flow control valves in the circuit. The pump and motor are necessary, in which both of them are both needed in one assembly or separate and can be put together by pipes or hoses. When fluid leak out inside and it goes back into the reservoir, it makes up for the loss using a charge pump. The...

Here is a list of hydraulic terms you may need to know the meanings. Absolute Pressure – this is when the vacuum is is at its best, when there is no air coming in at all. Accumulator – is a pressure reservoir in which an incompressible hydraulic fluid that is held under pressure by an external force of mechanical energy. Accumulator Effect – when there is a surge in the level of fluid in a hose that has the pressure building up. Aeration – when there is air in the hydraulic fluid that builds up the contamination. Cavitation – this...

Piggyback pumps are a series of pumps on one drive shaft. They have different reservoirs and have different fluids pumped into each pump. This will give the most optimum performance to be able to do the job at hand, to switch over when the operator needs to. Uses for the piggyback pumps are to give better output situations, than just using multi pumps by letting the pump sections be determined by size to give the best outcome for the task at hand. While most of the input goes thru the drive shaft, the power comes from and goes out from...

Joystick Controller These joysticks are made to control two different applications while using one controller. You can use a ball knob, pistol grip that has a electric switch, a pilot joystick and a toggle switch. Foot pedal controller gives the person operating a better comfort to control this with their foot. You can also install a mounting plate to the floor. But this a special order. This can give control and comfort to be able to offer pedal force of 10 – 15lbs. And offer 50 to 500 PSI pressure. The detent stackable controllers have different options that let you...

These pumps are 18 to 132 gpm at 1000 RPM’s with pressures up to 6000 PSI. They offer open circuit and closed. The closed units rotate either way, but having auxiliary pumps make it go in one direction. Closed circuit are just one direction. They are simple in design and are small, fixed or variable displacement units. They can go either way and any rotation. When you want to control the flow of a variable displacement unit you can tilt the swashplate. Several pistons are put in to place axially in a cylinder barrel that goes to the main mover...
