Peristaltic hose pump

Convenience food manufacturer, Greencore Group, is reported to have achieved significant savings in downtime and repair costs on the water treatment plant at its Greencore Grocery site in Selby, North Yorkshire, thanks to the installation of a Bredel SPX50 high pressure peristaltic hose pump from Watson-Marlow Pumps Group.

The facility is used to produce a wide range of sauces, pickles, and soft drinks. The cleaning and change-over process between products produces a small quantity of liquid waste (food effluent).

This can lead to significant fluctuations in pH levels, which are corrected using Mag Mex 1060, a magnesium hydroxide solution.

Carrier water is used to dose the Mag Mex into the system. To cope with the abrasive nature of this solution the Bredel SPX50 high pressure peristaltic hose pump (50mm diameter) is used. The peristaltic design means there are no valves, seals or glands to repair or replace. Replacing a hose or tube takes only minutes and they are relatively low-cost items compared to spares for other pump types.
