P50/P51 Tandem Pumps – Pressure And Sensing Unloader Pumps   When dealing with the flow sensitive unloader pumps there is a fixed orifice the valve that is linked to the flow preferences of the machine at a certain engine speed. Then there is spring loading that keeps the spool in the high flow position.  Should the operator maximizes the engine speed, it will make the pump flow go beyond the settings that were programmed into it. In turn this will increase the hydraulic imbalance that is made, that makes it shift the spool and unloads one of the pumps section.  Also,...

P50/P51 Tandem Pumps With Built In Unloading Valves Pressure Sensitive Unloader Pumps There are sensing valves that have cross connected when you use tandem pumps with the use of unloaders on the same engine. These valves are sensitive to pressure. They have the use of an extra port so that the relief valve housings can take in a pilot signal when it is on opposite ends of the unloading pump.  When you have cross sensing like that you can have higher pressure on one circuit and have still have constant speed on the other one. Relief valves preferences can be set...

Vickers Hydraulic Single Pumps 20VQ, 25VQ, 35VQ and 45 VQ   Pumping Cartridge Fluid flow starts in the pumping cartridge. The rotor starts within the ring where the drives shaft is that is attached to a power source. You will notice when the rotor turns the centrifugal force on the vanes, that are guided by under vane pressure that is fed by the outlet port. This will make the vanes want to go behind the elliptical inner surface of the ring. When you have radial movement of the vanes and rotating of the rotor, it will make the chamber volume...
