These compact high-pressure pumps can be used on portable power packs for high- pressure torque wrenches and other service tools.
Typical Applications Reduced power requirements, as low as 1.0 HP at 10 000 psi (0.7 kW at 700 bar), make these pumps ideal for use in remote locations with limited power supply. PUMP DESCRIPTION Fixed displacement checkball pumps, with bi-directional shaft rotation, provide constant direction of output flow regardless of the direction of drive shaft rotation. Multiple Outlet Pumps In Split-Flow® models, the piston outputs can be isolated, or grouped together in various combinations, supplying flows to multiple function circuits without flow dividers. Piston outputs are combined in the pump barrel or cover, and then discharged from the pump outlet providing smooth flow to the system. The outlet checkball then lifts off its seat and fluid is pumpedĪcross the check valve, out of the pumping chamber. Fluid is drawn by vacuum into the piston pumping chamber in the barrel.Ĭheck Valves Control Fluid During compression, the inlet check valve closes and pressure in the pumping chamber rises until it exceeds load pressure at the outlet port. During its suction stroke, each piston is filled through its inlet check valve. The angled surface of the wobble plate imparts a reciprocating motion to the pistons which move in and out of the bores in the stationary barrel. Wobble Plate Rotates with Shaft During operation, a fixed angle wobble plate rotates with the drive shaft. HOW THE PUMPS OPERATE The checkball pump design uses two check valves in each piston pumping chamber to direct flow from the inlet side of the pump to the pump outlet port.
