A MasoSine SPS series pump PRODUCTIVITY
from Watson-Marlow
Pumps Group has
transformed the efficiency
and reliability of a bead mill
at the Broadstairs facility of
speciality ink producer, FSIS.

The company previously
used an air-operated
diaphragm pump but had to
battle against excessive
friction and heat which had
the effect of curing a vital ink
component, turning it from
liquid to gel, and leading to
machine seizure.

Productivity services
manager, Trevor Cornock,
says: “A certain viscous ink
component we use has a UV
monomer type base that may
cure when exposed to
temperatures above 50°C.

Our previous AOD pump
generated a fair amount of
friction; this converted to
heat and caused the ink
component to turn from
liquid to gel when
temperatures exceeded 60°C,
which would eventually bring
the bead mill to a halt.”
Watson-Marlow
recommended its MasoSine
SPS series. Its design features
a sinusoidal rotor and
produces powerful suction
with low shear, low pulsation,
gentle handling and,
importantly for FSIS, very
low friction. Initial trials have
proved a resounding success.

MasoSine SPS pumps offer
capacity to 91.2m3/h and
pressures to 15 bar.
