Problem: Specialist in the application of pre-applied locking and sealing processes for threaded components, Prelok, encountered problems using both impeller and diaphragm pumps to circulate adhesive coating fluids at its Willenhall plant in the West Midlands.
Solution: Prelok turned to 521 Series peristaltic pumps from Watson-Marlow. Used in combination with Gore Style 400 high resilience tubing, the solution overcame problems caused by previous pumps of damaging the fluid, or of the fluid damaging the pump.
In peristaltic pumping operations, nothing but the hose or tube touches the fluid, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump.
So impressive was its performance that the company now has a total of four 521 Series pumps at Willenhall, with a further four dotted across its European operations. All of the units utilise an inverter to control speed, and all run continuously throughout the entire production period.
