Hy-Pro Drive PR+ REVERSING ELECTRO-HYDRAULIC POWER UNIT
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 Hy-ProDrive power units are the best available.
Product Description
Description
A permanent magnet DC motor driven precision gear pump available with a range of flows from 0.6 to 2.5 L/min. Each pump is fitted with zero-leakage pilot check valves for positive locking of steering cylinders.
The two service ports and reservoir port are positioned at the front of the pump. The threads are G1/4 (BSP) parallel. There is an optional second reservoir port on the top face accessed via a removable plug. If top mounted ports are preferred a kit is available to provide this option.
Relief valves to limit the maximum pressure generated are available as a further option.
The motors are maintenance free with internal brushes giving typically a 4000+ hour life. The front and rear bearings are sealed ball races for smooth and quiet operation. They have an Ingress Protection rating of IP67. They have a nominal output of 100W with a 50W option on the 12V PR+10 pumps.
The pumps are sealed on the driven gear journal allowing the motor to be removed without air entering or oil loss from the hydraulic circuit.
Application
Designed specifically for the marine autopilot market they are used by the worlds leading autopilot manufacturers. They can be used with balanced or unbalanced cylinders and are suitable for use in pressurized reservoir systems.
