Product Overview
▔▔The Parker Hydraulic Plunger Pump (commonly referred to as a piston pump) is a heavy-duty, high-performance displacement pump engineered for demanding mobile and industrial hydraulic systems. Known for exceptional volumetric efficiency, long service life, and robust pressure handling, Parker plunger pumps deliver reliable power density under extreme operational conditions.
Key Advantages
▔▔-
High Operating Pressure: Capable of continuous working pressures up to 350–420 bar (5,000–6,000 PSI).
Superior Volumetric Efficiency: Precision-machined plungers minimize fluid bypass and thermal loss.
Compact Power Density: Provides high power output relative to its physical footprint.
Low Noise Emissions: Advanced swashplate and port plate design significantly lower operational noise levels.
Versatile Controls: Available with pressure compensation, load sensing, electronic displacement, and torque limiting controls.

FAQ
▔▔
Q1: What is the main difference between a Parker plunger pump and a gear pump?
A: Parker plunger (piston) pumps handle much higher operating pressures (up to 420 bar) and offer variable displacement options for dynamic energy saving, whereas gear pumps are generally fixed displacement and suited for lower-pressure applications (under 250 bar).
Q2: What type of hydraulic oil should be used with Parker plunger pumps?
A: Premium mineral-based hydraulic oils meeting ISO VG 32, VG 46, or VG 68 (DIN 51524 part 2/3) are recommended. Synthetic or fire-resistant fluids can also be used, provided compatible seal materials (such as Viton/FKM) are specified.
