Quiet Running 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.
Quiet operation with noise levels as low as 72 dB(A) at 7m (23ft).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 re-builds.
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 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.
