Service areas
To facilitate future servicing of pump and electric
motor, lifting gear, such as access for cranes, lifting
points, ceiling beams or other approved equipment
for the purpose, should be installed. Carefully
consider where the pump installation will be placed,
as transportable approved lifting gear often needs
considerable space.
* If there is no permanently-installed lifting gear, an
approved lifting beam is required.
*Note: Some pumps have a service area
underneath.
Insulation
Pumps supplied by DESMI can not generally be insulated for
heat except at the top of the pump housing
- i.e. up to the base flange on the motor bracket as shown
below.
No holes or screen openings on the motor bracket
can be covered by insulation.
An electric motor will become hotter if mounted on a fully
insulated pump. The ball bearings and/or windings coils in the
motor can overheat if a pump is insulated all the way up to the
motor flange.
Unrestricted ventilation of the motor bracket is therefore
necessary to provide sufficient cooling of pump and motor
bearings
– both in pumps with bearings (/-02 or Spacer version)
and without bearings (/-12 version).
