Gear pump pipette

The suction port of the gear pump generally larger diameter, diffusion is sometimes used to form the suction port to expand the volume of the low pressure zone to reduce the flow rate of the liquid inlet to reduce the suction resistance of the pump. This structure can also reduce the effect on the journal bearing and the radial forces, extend the service life of the gear pump.

Pipeline output gear lubrication pump is mounted a check valve, so that when access to the pump and output pipes, the system will not backflow of liquid; gear lubrication pump with load stop, generating a partial vacuum within the output conduit, the prevent the pump reverse. Gear pump discharge piping valve protection device is also provided, so that once the pump outlet passage blocked, you can open the safety valve relief. Safety valve and pump or pump cover can cast one, also can be fitted separately.
