Centrifugal Pump
Description Of Unit
The pump is an end suction centrifugal pump with a fully automatic
priming system built into the design. This enables the pump to self prime
from completely dry conditions, even with extended suction lines. Liquid
is not required to prime the pump, and therefore, in temporary dry trench
conditions, the pump will ‘snore’ until such time as liquid is available.
The priming system utilizes a standard air compressor which feeds a
pneumatic ejector that is mounted above the air/water separation tank.
With this device, suction lifts up to 27 ft (8.2m) can be achieved.
The pump can handle raw unscreened sewage, trade effluents, thick
slurries and solids up to a normal limitation of 3.5” (90mm) diameter.
The impeller is of a two bladed fully open design, of 316 stainless
steel construction. It is mounted on a 431 stainless steel shaft fitted to
a cast iron bearing bracket; which also provides concentric location for
the pump volute. The pump volute is close-grained Ductile Iron fitted with replaceable 316
Stainless Steel wearing parts to simplify and reduce costs of pump rebuilds.The mechanical seal is leak tight and suitable for sewage and sludges.
The seal uses a silicon carbide rotating face mounted to a silicon carbide
stationary seat with Buna-N or Viton seal elastomers. The arrangement incorporates a
glycol water mixture-filled seal housing to lubricate the seal faces.
Guards are fitted as standard to all moving parts.
