This manual is intended as a reference guide for correctly installing and maintaining the RPU80, RPU160 and RPU300 reversible pumps.
The document serves as a reference guide for correctly installing and maintaining the Simrad RPU80, RPU160, and RPU300 reversible pumps. It details the relationship between these pumps and complete autopilot systems, including specific compatibility with various hydraulic steering gears.
Key sections cover mechanical and electrical installation procedures, oil filling and bleeding techniques, and comprehensive maintenance steps for dismantling the electric motor and valve block. The manual also includes a detailed fault tracing section to diagnose issues such as pump failure, rudder drift, or excessive noise.
| Max Flow Rate RPU160 | 1,6 l/min. |
|---|---|
| Max Flow Rate RPU300 | 3,0 l/min. |
| Test Pressure for Flow Rate | 10 bar |
| Nominal Voltage | 12 VDC |
Any well known hydraulic oil with a viscosity between 15-70 cSt at 40°C can be used.
Experience has shown that a rudder time between 10 and 15 seconds hard over to hard over normally gives the best steering performance.
The pumps work with J300, J3000, all "X"-models of junction units and ACXX Autopilot Computers.
