Parker PVP Series Pump | PVP16, PVP23, PVP33, PVP48 | Injection Molding Machine Pump | PVP1636R212

Parker PVP Series Variable Displacement Piston Pumps for Injection Molding Machines

Product Overview: The Parker PVP series serves as the high-performance heart for global injection molding machinery and medium-duty industrial hydraulic systems. This series spans from the compact 16cc (PVP16) and 23cc (PVP23) up to the high-capacity 48cc (PVP48). Featured models include the PVP1630R212, PVP1636R212, and PVP3330R21. Specifically optimized for applications requiring frequent duty cycles and precise pressure modulation, the PVP series utilizes high-strength cast-iron housings and advanced compensator technology to ensure elite power stability during mold clamping, injection, and holding phases.

Key Technical Advantages:

• Optimized for Injection Molding: Reinforced for high-frequency pressure switching typical in plastic processing, featuring millisecond dynamic response to shorten cycle times.

• High-Reliability Rotating Groups: Equipped with specialized hardened pistons and swashplates, maintaining ultra-low wear at continuous 250 Bar pressures to extend maintenance intervals.

• Compact Industrial Profile: The short-body design offers various SAE flange and shaft options, allowing for seamless installation within the confined tank spaces of modern injection machines.

• Exceptionally Low Noise Levels: Patented silencer grooves drastically reduce fluid ripples, enhancing the indoor factory floor environment.

• Versatile Compensator Controls: Offers Pressure Compensation, Load Sensing, and Remote Pressure control to match system power demands precisely, supporting energy-saving initiatives.
