PR2 piston pump driven by a GR2 gear pump

Technical Description

The PR2-GR2 combined pump is a fixed-displacement, two-stage unit that couples a Group 2 gear pump (low pressure) with a 2-piston radial piston pump (high pressure). Designed for external or submerged mounting and with reversible rotation, it operates between 300 and 1800 rpm, ensuring a significant flow supply and constant thrust.

The system uses mineral oil (DIN 51524/51525) with 60-90 μm filtration and ideally operates between 30°C and 50°C. With an optimal operating viscosity of 10-30 cST, the PR2-GR2 is a robust and precise solution, capable of minimizing pressure losses even during intensive industrial work cycles.
