Lubricating charge pumps turn out lubricating oil to bearings, gears and other parts. The oil acts as a coolant for the clutch plate and brakes. The operating pressure is around 300 PSI and the relief valve setting to 500 PSI when cold weather you need to start up. You have scavenge pumps take oil from the transmission from the passageways to the sump pump and send it back to the reservoir where the charge pump is. Most times they operate on 50 PSI and are made to operate in poor inlet circumstances, huge vacuums and spray of air and oil....

These pumps are small in size, capable of different applications, productivity, power and speed. They are useful in automotive, marine, medical and military. Some characteristics of these pumps are : .1 to .865 displacement per rotation made for open circuit systems fixed displacement – output is limited by the motor speed functional temperatures can go from 40 degrees – 300 degrees extracted 5000 RPM and relying on density. low noise when it is operating the ports are on the sides and rear quick output response can work on thin layer of oil several pumps, different configurations and bi directional pumps...

This is a tandem pump that has a flow sensitive unloading vlave and power for a port on the unloading pump. It has a main and secondary discharge ports that either pump is changed to the main port when it is at it’s lowest speed. When it is at an intermediate speed, one of the pumps is metered at the main port and changed over to the secondary port. Also, when you choose which speed you want, the pump is then changed over to the secondary port. Comined Flow Range …………………………………To 197 GPM Displacements ……………………………………………To 9.10 Each Section Maximum Pressure…………………………………….2500...

Valve float is an adverse condition which can occur at high engine speeds when the poppet valve in an internal combustion engine valve train do not properly follow the closure phase of the cam lobe profile. This reduces engine efficiency and performance. There is also a significant risk of severe engine damage due to valve spring damage and/or pistons contacting the valves These valves are used in conjunction with 4 way, 3 position valves to give a float or roving position. The application that these valves are best suited for are on snow plows, loaders, winches and equipment that have...
