Vickers Flex Plate Type Double Pump – VQ Series

2520, 3520, 4520, 3525, 4525 & 4535

The plates for the inlet and outlet are the same. The pressure goes behind both sides of the plate that go into two kidney shaped cavities. Then it sealed by unique seal pack subassemblies. The plates and kidney cavities work together by having the pressure build up in the outlet and the cavity. The pressure in the cavity hold up the flex side plates hydrostatic level against the rotor and gives the running clearance for minimum internal leakage and friction.

The plates give passage for feeding under the vane pressure to open area between the vane and insert.  The bronze side of the plate hold up wear and cold start. The inlet and outlet provide the plates to support the flex side plated to maintain away for the fluid to pass from the inlet in the pumping cartridge and from the cartridge to the outlet port.
