There’s a chill in the air and frosty mornings are becoming
more frequent as autumn gives way to winter, which means it’s time to start
protecting your electro-mechanical equipment to see it through the cold months.
Pumps are no exception, and here we highlight a couple of the most common
threats to pumps during winter.
Thermal shock
When a cold pump is activated, the fluid being moved may be
warmer than the components of the pump. If this is the case, thermal shock can
occur and cause parts such as the impeller, shell and suction liner to crack.
Thermal shock can be avoided by bringing the pump components up to temperature
gradually with external heat. However, don’t use a blowtorch or other
open-flamed device as these represent a fire risk. Use a portable heater
instead.
Inadequate drainage
After a pump is shut down, some liquid may remain in the
bottom, which in sub-zero conditions will freeze and expand. Components and
casings will fracture under the pressure, but the problem won’t become apparent
until the ice thaws and your pump leaks when started up. When shut down, pumps
should be drained off via the drain valve which can be found at the lowest
point. If your pump is not fitted with a drain valve, consider having one
installed so you can be certain the equipment is completely empty of fluid when
not in use.
