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.
