Seiko Manufacturing Professional Design

Complete models and stable quality

Low noise and low heat

product feature：

1. The design is reasonable, and the pump core adopts the circular blade with precision machining, which reduces the compressive stress of the blade on the inner curve of the stator, and also improves the service life of the stator and the blade; 2, the stator adopts a high power no impact transition curve, so that the blade has a good motion and stress state, so that the blade and the stator are in good contact, and the flow loss, pressure and flow fluctuation are minimal, low noise, high life; 3, the side plate adopts hydraulic balance, can obtain better volumetric efficiency; 4, key parts of the selection of high-quality materials and efficient heat treatment process, the overall reliability of the oil pump to further improve; 5, the use of plug-in structure, the main internal parts into the form of components, pump core replacement can be completed in a few minutes, good interchangeability, easy maintenance 

Specification

★1.In case using socket welding flanges,there is a case where the operating pressure should be set lower than the normal because of strength of the flanges.Therefore,please pay cautious attention to the operating pressure when the socket welding flanges are used.

★2.As dimensions of the pipe flange mounting surface are conformed to SAE 4 Bolt Split Flange(Standard Pressure Series),pipe flanges conforming to the SAE Standards can be used.

Notes:Special seals(Viton seals)are required when phosphate ester type fluids are used.(Prefix "F-" to the pipe flange kit number when ordering.)

●Details of the pipe flange kits are shown on page 824.

Instructions for use

To protect your rights please read the following carefully

Pump Start-up Procedure 
Preparation Prior to Start-up 
The reservoir and circuit should be clean and free of dirt and debris prior to filling with fluid. 
Circuit Cleanup 
The reservoir should be charged with filtered hydraulic fluid. The fluid level should be sufficient to prevent vortexing at the suction connection to the pump inlet. It is good practice to clean the system by flushing and filtering, using an external slave pump. 
Filling Pump and Removing Air 
If the pump is mounted above the fluid level, it should be filled with fluid through the outlet port. If the pump is mounted below the fluid level, the pump outlet fitting (or other downstream fitting or plug) can be loosened to allow fluid to displace the air. It may be necessary to loosen the fill cap on the reservoir to allow the fluid to flow freely. When a solid stream of fluid with no observed air begins to drain through the loosened fitting, the fitting should be retightened. An air bleed valve in the outlet circuit is also recommended to remove trapped air. If such a device is used, the pump should be filled with fluid before start-up. In some cases, it may be possible to prime the pump by running the engine starter for five to ten seconds with the throttle and/or ignition switch in the "off" position. It will be necessary to loosen a fitting or plug in the pump outlet to allow air to escape. 
Pump Start-up 
All controls should be placed in the neutral position so the pump is unloaded when started. Start the engine and run at low idle. Once the pump is started, it should prime and pump within a few seconds. If it does not, make sure there are no restrictions between the reservoir and the inlet to the pump, and that there are no air leaks in the inlet line and connections.  Also, make sure that trapped air can escape from the outlet. Run at low engine idle for approximately five minutes. Then, while observing the reservoir fluid level, operate the implements. Extend all actuators to maximum safe limits to completely fill the system with fluid. Do not run with the fluid level below the "low" limit. Add fluid to the reservoir to bring the fluid to the proper fill level.
