Suitable applications Peristaltic pumping is ideal for most fluids, including viscous, shear-sensitive, corro- sive and abrasive fluids, and those containing suspended solids. They are especial- ly useful for pumping operations where hygiene is important. Peristaltic pumps operate on the positive displacement principle. They are parti

DuN, Du 9 Good pump installation practice 9.1 General recommendations Position 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 flow of air around the pump to ensure that heat can be dissipated. Ensure that the temperature around the pump does not exceed 40C. Do not stack other 620 pumps on top of this pump. It is, however, acceptable to stack

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 620N watertight module is fitted the seals are intact and properly located. Ensure that the holes for cable glands are properly sealed to main- tain the IP66 / NEMA 4X rating. Do not strap the control and mains power cables together. Do keep delivery and suction tubes as short and direct as possible - though ideally not shorter than 1m - and follow the straightest

It is not recommended to site these drives alongside “dirty” electrical mains supplies such as 3-phase contactors and inductive heaters without special attention being paid to unacceptable mains-borne noise. The voltage selector is mounted in the switchplate at the rear of the pump, protected from water by the
