VANE PUMPS

Hydraulic Fluids 1. Type of hydraulic fluids Any type of hydraulic fluids listed in the Table 1 below can be used. However, the specifications of the pumps such as maximum pressure and maximum pump speed may be changed according to the type of hydraulic fluids to be used. For details, please refer to the specifications of the pump concerned. Hydraulic fluids Petroleum Base Oils Synthetic Fluids (Table 1) Use anti-wear type oils or R & O (Rust and Oxidation inhibitor) type oils (equivalent to ISO VG32 or 46). Use phosphate ester type fluids. When phosphate ester type fluid is used, prefix "F-"...

VANE PUMPS Instructions 2. Suction pressures Set the suction pressure at pump inlet port at the value given in the table below. Furthermore, use the pipes in the suction side having the diameter as indicated on the installation drawings. In case where the pump is installed on the tank or at the position higher than the tank top cover, the height of the suction port of the pump should be less than 1 metre (3.3 ft.) from the oil level {less than 0.8 metre (2.6 ft.) in case of using phosphate ester fluids or water containing fluids}. Suction Pressure Minimum Phosphate ester type fluid Petroleum...
