Peristaltic pump

The local water supply required treatment to prevent scaling in the pipework. 

The existing treatment system required a salt solution to be dosed from a storage tank close to the pumps over a 350m pipe-run to the water supply. However, the pipe work contained a large proportion of air.

Consequently, the magdrive pumps transferring the solution ran dry due to intermittent use, leading to bearing failure. The pumps had to be replaced every three months, resulting in plant downtime and high maintenance costs. 

A Verderflex Dura 35 peristaltic hose pump was recommended. As the only part in contact with the fluid is a flexible hose, the pump can run dry and tolerate air in the pipes. The pump itself was sized to run slowly, so as to increase the hose life.
