SA-DV-150i 6" 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 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,
thick slurries and solids up to a normal limitation of 3.0”
(77mm) 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 casing is fitted with replaceable wearing parts,
consisting of the impeller and wear plates, to simplify
and reduce costs of pump rebuilds.
The mechanical seal is leak tight and suitable for sewage
and sludges. The mechanical seal is fitted with silicon
carbide rotating and stationary faces and Buna-N or Viton�
seal elastomers. The arrangement incorporates an oil-filled
seal housing to lubricate the seal faces.
Material options include: Ductile Iron bearing frame
with a Ductile Iron pump casing and fitted with 316 stainless
steel or 2% chromium steel alloy (340 BHN) impeller and
wearplates; complete 316 stainless steel wet ends; complete
CD4MCu wet ends; or complete high chromium alloy (500 BHN)
wet ends.Guards are fitted as standard to all moving
parts.
