Product Description
PLP & PLM Series High-Performance Tandem Hydraulic Gear Pumps
Product Overview: The PLP and PLM Series serve as the essential power core for mobile hydraulic systems. As precision high-pressure gear pumps, this range covers full specifications from the compact PLP10 to the heavy-duty PLP30. This featured selection highlights its flexible tandem and triple configurations, such as the PLP20.4-01S1-LRD/20.6,3-LRM/RD/20.6. Engineered with three-piece high-strength aluminum construction and advanced pressure compensation, these pumps are designed to meet the rigorous demands of forklifts, refuse vehicles, and industrial machinery for high pressure (up to 28 MPa) and precise multi-circuit flow delivery.
Key Technical Advantages:
100% Plug-and-Play Replacement: Strictly adheres to industrial OEM specifications. Suffixes like 01S1 and LRD/LRM guarantee that mounting flanges (SAE or European standards), shaft ends (splined/keyed), and port positions are 100% identical for seamless installation.
Superior Pressure Resilience: Rated for a continuous operating pressure of 25 MPa (250 Bar) with peaks reaching 28 MPa (280 Bar), built to absorb high-frequency load shocks during demanding duty cycles.
Efficient Multi-Stage Integration: Supports various tandem combinations (e.g., PLP20+PLP20 or PLP20+PLP10), allowing a single drive shaft to power multiple independent circuits, saving significant installation space.
High Volumetric Efficiency: Featuring automatic axial gap compensation to minimize internal leakage, maintaining efficiencies over 93% throughout the pump’s service life and reducing system heat generation.
Ultra-Low Operating Noise: Precision-ground gear sets drastically reduce fluid ripples under high-pressure cycles, protecting downstream control valves.
