There are different controls for different pump and motors. Listed below will be a brief description of some controls. Two stage pressure compensator You will find that on SV pumps have a compensator that comes routine from the factory. These controls let the pump to compensate output flow to give coverage so the system can perform correctly. When your flow reduces, horsepower utilization is lessened, but the pressure stays the same. Solenoid two pressure compensator The electrical actuator provide two separate adjustable pressures for pilot operation, two speed controls and solenoid actuators. If you restore the solenoid it make have...

In the picture you will find the tapered roller bearings, they are like a fusion of a thrust bearing and journal bearing. And you will know it is a needle bearing because it is long, thin and they are good to use when you don’t have enough space to use other bearings. Ball thrust bearings and plain thrust bearings are used in the same manner. Ball bearings have a course of round balls in a casing that go within an inner and outer ring that can hold up to both radial and axial thrust loads Another oil-less bearing, that is...

Expansion bearings lets some of the axial shaft movement. These bearings are generally used in equipment where the shafts can become heated and expand. Non expansion bearings confine shaft movement and keeps the shaft and its components in the right position. They somewhat serve as a thrust bearing. Pillow block housings can be split or solid, in which it facilitates mounting. Pillow block bearings usually handle radial loads that pass into the base. When you have two or more pillow blocks used on a shaft, the other one needs to be non expansion to keep the shaft from moving in...

This pump is very durable in it’s makeup. It has a small size to fit in tight places in a tractor or excavator. Doesn’t make alot of noise when it is doing its job. You can rebuild this pump very easily. Has great horsepower control for when you have high and low pressures and the same on the flow rates. Has a load sensing control that helps with flow going thru an orifice and pressure that can go up and down in loads putting out less heat. It has five displacements to choose from. It has different flange mounting and...
