9 Good pump installation practice

9.1 General recommendations

A correctly engineered installation will promote long tube life. Site the pump on a flat, horizontal, rigid surface, free from excessive vibration, to ensure correct lubri- cation of the gearbox. Allow a free flow of air around the pump to ensure that heat can be dissipated. Ensure that the ambient temperature around the pump does not exceed 40C.

The STOP key on the keypad will always stop the pump. However, it is recommend- ed that a suitable local emergency stop device is fitted into the mains supply to the pump.

Do not stack pumps more than three high. When pumps are stacked, ensure that the ambient temperature around all the pumps in the stack does not exceed 40C.

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 for the 520R and 501RL pumpheads tube life will be greater if the rotor rotates clockwise; and that performance against pressure will be maximised if the rotor rotates counter-clock- wise. To achieve 4 bar and 7 bar pressures using a 520RE pump and the appropri- ate rotor and element, the pump must rotate 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. Users of 520RE pumps at pressures up to 4 bar and 7 bar are advised to fit a non-return valve between the pump and the discharge pipework to avoid the sud- den release of pressurised fluid in the unlikely event of element failure.

9.2 Do’s and do not’s

Do not build a pump into a tight location without adequate airflow around the pump.

Do ensure that when the 520N watertight module is fitted the seals are intact and properly located.

Do ensure that the holes for cable glands are properly sealed to maintain theIP66 / NEMA 4X rating.
