Product Introduction

Parker PGP50 PGP51 haldex gear pump

1. Key Features

Durable Construction:

Cast Iron or Aluminum Housing: High-grade cast iron pumps (e.g., Concentric Haldex models) offer exceptional strength and wear resistance for heavy-duty applications, while aluminum variants (e.g., W900 series) provide lightweight durability

Hardened Steel Gears: Precision-machined gears ensure longevity, even under high pressures up to 300–350 bar

High-Pressure Performance:

Operates at continuous pressures up to 276–300 bar, with peak pressures reaching 350 bar in specialized models (e.g., W900 and Ferra series)

Low Noise and Smooth Operation:

Pressure-balanced designs and optimized gear profiles reduce noise levels to <65 dB (e.g., WP900 series), ideal for noise-sensitive environments

Efficiency and Flow Control:

Volumetric Efficiency >95%: Achieved through minimal internal leakage and gap compensation technologies

Flow Rate Flexibility: Models like the Haldex Barnes pump deliver 9.8 GPM at 3,600 RPM, with displacement ranges from 0.8 to 161 cc/rev to suit diverse hydraulic demands.

Modular and Customizable Configurations:

Supports multi-pump setups (e.g., tandem or triple configurations) and integrates control valves for enhanced functionality

Broad Fluid Compatibility:

Handles high-viscosity fluids (10–300 cSt), including oils, resins, paints, and food-grade liquids

2. Advantages

Reliability in Harsh Environments:

Engineered for rugged operations, such as mining and construction, with contamination-resistant seals and thermal management systems

Energy Savings:

High efficiency reduces power consumption, aligning with sustainability goals

Versatility Across Applications:

Industrial: CNC machines, hydraulic presses, and injection molding

Mobile Equipment: Excavators, agricultural machinery, and municipal vehicles

Specialized Uses: Paint transfer, resin metering, and marine hydraulics

Low Maintenance:

Self-adjusting components (e.g., pressure-balanced bushings) and easy disassembly minimize downtime

Cost-Effectiveness:

Competitive pricing and extended service intervals lower total ownership costs compared to premium brands like Parker or Bosch
