VSM, with body in ductile cast iron and internals in stainless steel, sustains and discharges the upstream pressure regardless of variation in flow rates and downstream pressure pulsations. Simple, low cost and bench mounted it uses a pair of pneumatically powered single acting piston pumps, sized to give the required volumetric mix ratio. Fulflo valves minimize system power loss by reducing velocities through all but the controlling interface of the valve.

PERFORMANCE PREDICTIONS AND TEST RESULTS OF A FREE-PISTON STIRLING ENGINE DRIVEN HEAT PUMP D. Hydraulic Motors Line Card. 0770 -- fax 888. The remainder of this paper is organized as. Flows of 1. The pump tube is equipped with a dynamic primer († fig. Plunger and piston pumps. Positive displacement, reciprocating pumps can be classified as power pumps or direct acting pumps; horizontal or vertical pumps; single acting or double acting pumps, piston, plunger or diaphragm pumps; simplex, duplex or multiplex pumps. HPV SERIES AXIAL PISTON PUMPS GENERAL SPECIFICATIONS Maximum Inlet Pressure Recommended Fluids The maximum inlet pressure is 50 PSI at all speeds. S6CV series are variable displacement, axial piston pumps, with swash plate design, for closed circuit hydrostatic transmissions and high pressure applications.
