Pump it up
One of the major problem areas for hygiene and other problems
on a milking machine is in fact the milk transfer pump.
By COLIN MORRISON
Many of the larger rotary milking
systems will sometimes have
two pumps fitted, one which will
handle normal flow and another,
usually slightly larger to handle peak
As a past milking machine technician, I
would say that at least 75 per cent of
my emergency call outs were to faulty
The modern day milking machine uses
a centrifugal pump powered by an
electric motor, usually 3 phase.
These have largely replaced the older
diaphragm type pump found on
herringbones and older rotary milkers.
The trouble with electric motors
however is that they do not like water
and milking sheds are usually a very
All steps are taken to ensure that
pumps are kept dry and stainless or
plastic covers provided to keep the
majority of water out, but I have lost
count of the times I have witnessed
farm workers playing a high pressure
jet of water direct at a milk pump.
Another problem with a centrifugal
pump is the mechanical seal, these are
usually made of carbon and will not
stand being run whilst dry, very soon
they will start to leak and milk will seep
behind the seal and will usually end up
causing a thermoduric grade.
Farmers should check daily for signs of
any milk leaking from the head of a
milk pump. I recall going to a 32 aside
herringbone shed one day where the
farmer was having problems getting
the milk away, he insisted that he
pulled the pump apart on a regular to
check and clean it. When I stripped it
down, the smell was disgusting and
there were maggots behind the seal!!
Most technicians will sell the farmer
spare seal, impellors and
faceplates etc and give
instructions on how to fit
For trouble free milking,
ensure that any pump covers
supplied are fitted and in good order.
Take them off occasionally and clean
inside with a brush and warm water.
Make sure that all connections and
rubberware to and from the pump are
in good order and that there are no air
leaks -- a pump will suck air before it will
Look for signs of air bubbles in the milk
can, this is the sign of an air leak
between the receiving can and the
pump or perhaps the non return valve
is held open by a stone.
If in any doubt, call the milking machine
technician in to solve the problem for
you. Make sure that he shows you what
the problem is so that you can check it
if it should occur again.
