4 Good pump installation practice

114DV, 114DVP 4.1 General recommendations

A correctly engineered installation will promote long tube life.

The pump may be set up so that the direction of rotor rotation is clockwise or count- er-clockwise, whichever is convenient. Please note, however, that tube life will be greater if the rotor rotates clockwise; and that performance against pressure will be maximised if the rotor rotates counter-clockwise.

Peristaltic pumps are self-priming and self-sealing against backflow. No valves are required in inlet or discharge lines, except as described below. Valves in the process flow must be opened before the pump operates. Users are advised to fit a pressure relief device between the pump and any valve on the discharge side of the pump to protect against damage caused by accidental operation with the discharge valve closed.
