Parker PVP33 Series Piston Pump | PVP3330, PVP3336, PVP3326 | Variable Hydraulic Pump

Parker PVP33 Series Axial Piston Variable Displacement Pump

Product Overview: The Parker PVP33 series is a high-performance, swashplate-type axial piston pump engineered for Open Circuit industrial hydraulic systems. This range is a premier choice for plastic machinery, metalworking equipment, and various medium-pressure power units. Featuring a heavy-duty cast-iron housing and optimized internal flow paths, the PVP33 series delivers operating pressures up to 210 Bar with exceptional vibration dampening and quiet performance. Core models such as the PVP33303R6A220 and PVP3336R2VM21 are renowned for their high power density and sensitive compensator response.

Key Technical Advantages:

• Versatile Control Options (A2/VM/A5): Equipped with high-precision compensators. Models like the PVP33-36R-2VM21 support remote pressure control, while the PVP3330D2R6A5A21 integrates advanced load sensing and pressure compensation, modulating flow instantaneously based on load to drastically cut energy consumption and heat buildup.

• Heavy-Duty Shock Resistance: The high-strength cast iron body is reinforced for continuous, high-frequency operation in industrial environments. The PVP33262R16T15 model demonstrates superior volumetric efficiency even at reduced displacements, ensuring an extended service life under heavy-load cycles.

• Optimized Acoustic Characteristics: Parker’s proprietary noise-reduction technology minimizes pressure pulsations, making the PVP33 the preferred choice for factories with strict noise level requirements, such as precision machining workshops.

• 100% Industrial Interchangeability: Manufactured strictly to Parker OEM standards. Whether featuring R6 (Clockwise) rotation or specific porting layouts, these units provide a seamless “drop-in” match for original equipment, significantly reducing maintenance downtime.
