8/3/2019 A Centrifugal Pump is a Machine Used for the Purpose of
Transferring Quantities of Fluids and or Gases, From One
2/2
The pump casing is designed for multi position outlet, with 360
flexibility.
Back Plate
The back plate is of pressed stee l manufacture, which together
with the pump casing form the actual fluid chamber in which the
fluid is
transferred by means of the impeller.
Mechanical Seal
The connection between the motor shaft/pump shaft and the pump
casing is sealed by means of a mechanical sea l.
The link below provides a ll information on pump seals.

Shroud and Legs
Most pump types are fitted with shrouds and adjustable legs. The
shroud is insulated to keep noise to a minimum and protect the
moto
damage.
Pump Shaft/Connections
Most pumps have stub shafts that are fixed to the motor shafts
by means of compression couplings, eliminating the use of keyways.
Th
shaft assembly design provides a simple, yet secure method of
drive that reduces vibration and noise. On the multistage
centrifugal pu
length of the pump shaft will differ depending upon the number
of impellers fitted.
Adaptor
Most pumps are fitted with a standard IEC electric motor. The
connection between the motor and back plate is made by means of an
ad
which can be attached to any standard IEC or C-frame electric
motor.
Pumps supplied with direct coupled motors have no adaptors.
