Dynex/Rivett Inc. presents "Hydraulic Checkball Pump Operation". The rotating wobble plate imparts a reciprocating motion to the pistons. During its suction stroke each piston is filled through its inlet check valve. During compression, the inlet check valve closes and pressure in the pumping chamber rises until it exceeds load pressure. The outlet checkball then lifts off its seat and fluid is pumped out of the chamber. The piston outputs are combined in the pump cover and discharged from the outlet.

Dynex checkball hydraulic pumps use two check valves in each piston pumping-chamber to direct flow from the inlet side of the pump to the pump outlet port. This pump design operates reliably with a wide range of fluids at high pressures. The positive-seating check valves provide better wear and higher volumetric efficiency, especially with low-viscosity, low-lubricity fluids.
Operating benefits include:
VERTICAL MOUNTING: Unlimited pump orientation provides circuit flexibility.
BI-DIRECTIONAL ROTATION: Constant flow direction regardless of drive shaft rotation.
PRESSURES TO 20,000 PSI: The design provides a high horsepower-to-weight ratio handling higher loads than other pumps.
WIDE RANGE OF FLUIDS: The check valves provide better wear and higher volumetric efficiency with low-lubricity/low-viscosity fluids.
NO LUBRICATING OIL REQUIRED: Only the pumped fluid is required for internal lubrication, eliminating a secondary lubrication circuit and reducing maintenance.
CONTAMINATION TOLERANT: A large flow path into pistons, and output through the outlet check valves, allows contamination to be flushed through the pump.
RESISTANT TO CAVITATION: The outlet checks do not unseat until pumped fluid reaches load pressure, providing reduced decompression shock and resistance to cavitation damage.
SPLIT-FLOW: Multiple outlet pumps simplify multiple-function circuits using only one pump, and provide greater output-flow accuracy than flow dividers for synchronized movement.
