SA-DV-300i 12" x 12" 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 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 VitonTM
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.
