Michael Smith Engineers
has supplied a Micropump
and inverter system to
Huddersfield-based Specialist
Glass Products. It was needed
for the process of making
reinforced laminated doubleglazed
panel sections.

Michael Smith Engineers
was asked to provide a
pumping system that would
deliver a smooth, even and
accurate output to reduce the
chance of entrained bubbles
forming when UV resin is
introduced between two
panels. The brief was for the
pump to have a sealless magnet
coupling so resin will not be
exposed to air which causes it
to harden, and it had to afford
automatic slowing down of the
pump at the end of the batch
to prevent overfilling. The
need was for a pumped batch
metering transfer system for
acrylic monomer resin with a
viscosity of 100cP. This was
designed to draw resin from
the base connection of a 1000L
IBC at a flow rate between
0.1 and 1.2L/min in metered
batch sizes of 0.1 to 10L.

The system comprised a
Micropump with an inverter
controlled motor with
integral dual channel encoder
for operating at speeds to
2100 RPM.
