  • What is Pump

    However pump priming is required for the centrifugal pump as the impeller cannot create much pressure difference in the pump Step#3 Limitation of Negative Pressure Pressure should not be below the vapor pressure else bubbles will be formed and cavitation can occur which will damage the pump.
