Backed with over 30 years of continuous development the new PR+ range of reversing pumps presents the ultimate in quiet and smooth operation. Unlike noisy piston pump designs the precision gear form delivers smooth flow in all conditions and with minimal noise. Now with IP67 motors that have a 4000 hour brush life these latest generation of Hydraulic Projects power units are the best available.
The PR+ pumps are available in 0.6, 0.8, 1.0, 1.5, 2.0 and 2.5 litre per minute flows. Pilot check valves are fitted as standard, they can be used with both balanced and unbalanced cylinders. They have an advanced protective coating designed especially for the salt laden atmosphere of the marine environment.
