SA-DV-200c 12" x 8" 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 mounted above the air/water
separation tank. With this device, suction lifts up to 28ft.
(8.5m) 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
and solids up to a normal limitation of 3.0” (76.2 mm) diameter.
The impeller is of a 2 port enclosed non-clog design,
of cast iron construction. It is mounted on a LaSalle 1144
stress proof shaft with AISI 416 stainless steel shaft sleeve
fitted to a cast iron bearing bracket; which also provides
concentric location for the pump volute.
The pump casing is fitted with replaceable wearing parts,
consisting of the impeller and wear rings, to simplify and
reduce costs of pump rebuilds.
The mechanical seal is leak tight and suitable for sewage
and sludge. The mechanical seal is fitted with tungsten
carbide vs. silicon carbide faces and Buna-N or Viton seal
elastomers. The arrangement incorporates an oil-filled seal
housing to lubricate the seal faces.
Material options include: Cast Iron bearing frame
with a Cast Iron pump casing and fitted with 316 stainless
steel or CD4MCu impeller and wear rings; complete 316 stainless
steel wet ends; complete CD4MCu wet ends.
Guards are fitted as standard to all moving parts.
