At the Tenbury Wells plant of
Kerry Ingredients & Flavours
a MasoSine SPS 2.5 sine
pump from Watson-Marlow Pumps
Group has demonstrated its
capabilities for handling the
demanding viscosity and flow
properties of condensed milk. The
pump’s sinusoidal rotor overcame the
limitations of a previouslyconsidered
rotary lobe pump to
produce powerful suction with low
shear, low pulsation and gentle
handling and proved just right for
the company’s new toffee sauce.

When the plant wanted to introduce
the sauce to its 10 production lines, it
was faced with the challenge of
pumping condensed milk. Initially,
volumes were small, typically 1-2
batches at a time, and so Kerry could
use manual labour for the task.

However, demand grew and a more
automated solution was required.

A MasoSine SPS 2, on trial for
another application, was tested to see
whether it could handle condensed
milk. It made light work of the task.

Process manager, Charles Bishop-
Miller, says: “We estimate the sine
pump offers 20% faster pumping
times than the lobe pump. It has also
allowed us to redeploy the labour
resource to a more value-added role.

Greater versatility, self-priming ability
and ease-of-cleaning also stack in
favour of the MasoSine pump.”
