Technical accuracy To the best of our knowledge, the information in this handbook was correct when it went to press. However, Raymarine cannot accept liability for any inaccuracies or omissions it may contain. In addition, our policy of continuous product improvement may change specifications without notice. As a result, Raymarine cannot accept liability for any differences between the product and the handbook. - Page 7 The Raymarine hydraulic pump (also known as the Raymarine constant runninng hydraulic pump) is intended to operate a vessel’s steering mechanism as part of a Raymarine autopilot system. It is primarily designed for use on vessels with an existing hydraulic steering system. Alternatively, you can use this pump on a vessel with mechanical steering in conjunction with a secondary steering ram.

3. Hydraulic connections WARNING Pressurized systems Before disconnecting any pipes on pressurized systems, you MUST release the pressure at the reservoir by following the manufacturer’s instructions. CAUTION Pump connection Before you connect the autopilot pump to your hydraulic system we strongly recommend that you consult the steering gear manufacturer. -
Page 13: General Guidelines
General guidelines • The ports on the autopilot pump are in BSPP and 3/8 in BSPP parallel threaded. If you need to convert to in NPT, use the three BSPP to NPT adaptors (supplied). Use only bonded rubber / metal washers to seal the fit- tings. -
Page 14: Hydraulic Fluid
CAUTION Hydraulic fluid • Before running the pump for the first time, make sure the system contains sufficient hydraulic fluid. You will damage the pump if you let it run when ‘dry’. • Do NOT use “brake fluid”. Use only mineral-based good quality hydraulic fluid compatible with nitrile rubber hydraulic seals. - Page 15 Two line systems Figure 6 shows a typical two line steering system. Hydraulic fluid flows into the ram in either direction, depending on the direction the helm pump rotates. Connect the autopilot pump to the steering system as shown in Figure 6. Figure 6...
- Page 16 Two line pressurized systems Two line pressurized systems have an external pressurized reservoir. This reduces the possibility of introducing air into the system and reduces any steering ‘sponginess’ caused by pipe expansion. Connect the autopilot pump to the steering system as shown in Figure 7. Note: Refer to the manufacturer’s instructions for de-pressurizing and re-pressurizing the system.
- Page 17 Figure 8 Three line systems In a three line system, the hydraulic fluid flows in only one direction: • out of the helm pump to the ram • returning from the other side of the ram to the reservoir via a common return line The system will include a check valve block to direct all returned fluid from the ram back to the reservoir.
