1. The gear oil pump is suitable for conveying various lubricated liquids. The temperature is not higher than 70 °C. If the temperature is 200 °C, contact with the unit can be used with high temperature resistant materials. The viscosity is 5×10-5～1.5. ×10-3m2/s. 2, gear oil pump is not suitable for transporting corrosive, hard particles or fibers, highly volatile or low flash point liquids, such as gasoline, stupid and so on. The gear oil pump is equipped with a pair of slewing gears in

Suction pressure ≤1.0MPa, or pump system high working pressure ≤1.6MPa, that is, suction pressure + pump head ≤1.6MPa, pump static pressure test pressure ≤2.5MPa, please indicate the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6 MPa, it should be separately proposed at the time of ordering, so that the over-flow part and the connecting part of the pump are made of cast steel material during manufacture.
