The role of the stuffing pump is mainly to close the gap between the shell and the shaft, to prevent the flow pump does not flow to the outside, it does not allow outside air into the pump.

If the transport of liquid viscosity and density difference between the larger and water, shall account for the pump parameters: flow, pressure head and shaft power.

The centrifugal chemical pump can achieve reasonable pressure and flow rate, ensure low energy consumption and effectively prevent the pump shaft from being corroded.
