Key Features & Benefits
Compact, Lightweight Design:
Engineered for tight spaces, the PGP50 and PGP51 feature a streamlined, three-piece cast iron construction that ensures durability without compromising on weight or footprint. Their compact design makes them ideal for mobile equipment, agricultural machinery, and compact industrial systems.
Enhanced Efficiency & Low Noise:
Optimized gear profiles and precision-machined components minimize internal leakage and reduce operational noise. Advanced sealing technology ensures stable performance even with low-viscosity fluids like synthetic hydraulic oils, enhancing energy efficiency and thermal management.
Versatile Pressure Ratings:
Continuous Pressure: Up to 250 bar (3,625 psi).
Peak Pressure: Up to 280 bar (4,060 psi) for intermittent loads.
These ratings make the pumps suitable for applications requiring reliable power in variable load conditions, such as material handling, construction equipment, and automation systems.
Wide Speed Range & Displacement Options:
Speed Range: 600–2800 rpm (recommended for optimal efficiency).
Displacement Options:
PGP50: 19.7 cc/rev (1.20 in³/rev).
PGP51: 26.2 cc/rev (1.60 in³/rev).
This flexibility allows users to select the ideal model based on flow requirements, with the PGP51 offering higher displacement for systems needing greater fluid delivery.
Robust Shaft & Bearing Design:
A hardened, one-piece shaft and oversized bearings ensure exceptional torque transmission and resistance to side loads, extending service life in applications with frequent starts, stops, or directional changes.Multi-Pump Configurations:
Both models support piggyback and thru-drive configurations, enabling integration into multi-pump systems for complex hydraulic circuits. This modularity reduces installation costs and simplifies maintenance.
Available Models:
G101/102 C101/102 P30/31 P50/51 P75/76 P315 P330/350 P365
