SA-HH-150 8" x 6" Sound Attenuated 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 1.5” (36mm) 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.
