Parker F2-55/28-L 3784129 Twin-Flow Hydraulic Pump – Flexible Power and Fuel Efficiency

The Parker F2 Twin-Flow pump is the perfect choice when you need to operate two independent hydraulic work functions simultaneously with precision and speed. Thanks to its dual-flow design, the pump can provide one large and one smaller oil flow, or two equal flows – fully adaptable to your system requirements. This not only increases work efficiency and operating accuracy, but also helps optimize fuel consumption.

Key Features & Benefits

  • Flexible performance: two different flows available at the same engine speed
  • Energy-efficient operation – reduced fuel consumption
  • Lower risk of overheating in the hydraulic system
  • Compact, lightweight, and easy-to-install design
  • Standardized system solutions for easier integration and servicing

Typical Applications

The Parker F2 Twin-Flow pump is ideal for heavy-duty trucks and machinery, including:

  • Snow ploughs
  • Large truck loaders
  • Refuse collection vehicles
  • Hook loaders / Lift dumpers
  • Tipper–crane combinations
  • Multipurpose trucks

Technical Specifications – at a glance

  • Displacement: 28–70 cm³/rev (Port A and B versions)
  • Max speed: up to 2100 rpm
  • Continuous operating pressure: 350 bar (max. 400 bar)
  • Maximum input power: 100–131 kW
  • Weight: only 19 kg

Why choose Parker F2?
Because it combines high performance, low fuel consumption, and unmatched reliability, making it the go-to solution for municipal, industrial, and heavy-duty transport applications.

Operating Principle

This pump operates on the bent-axis axial piston principle. Multiple pistons reciprocate within a rotating cylinder block as it spins, displacing hydraulic fluid. The tilt angle between the drive shaft and the cylinder block defines the stroke length of the pistons. With dual-flow design, two independent circuits can be powered simultaneously, improving operational flexibility. The construction provides smooth flow, high volumetric efficiency, and excellent pressure stability even during intensive use.
