Remove packaging but leave the flange covers in place, check that impeller rotates freely by hand by turning the shaft.
- Page 10 Discharge Pipework The bore of the discharge pipe should be sized to ensure a flow velocity of 2.5 to 3 m/s is not exceeded. This is usually one size larger than the discharge branch. Pipework should be as short and straight as possible to reduce friction head loss. A non-return valve is usually fitted to prevent the pump from excessive back pressure and reverse rotation and a discharge valve is usually fitted to regulate the flow and allow for inspection and maintenance on the pump.
