The PV202R1EC02, now known as the Parker Variable Piston Pump, is part of the Parker DENISON PV series. Many older pumps in the market bear the DENISON nameplate, as Parker acquired the DENISON piston pump product line, which now falls under the Parker flagship brand.

Notes:
When using the Parker piston pump, careful attention should be paid to the casing pressure during high-speed operation, as rapid pressure compensation variation can cause casing pressure spikes. If the system’s directional control valve is a quick-closing O-ring (center closed) valve, both drain ports on the hydraulic pump casing should be utilized. Drain lines should be short and direct, and an overflow valve should be installed in the system for proper configuration.
