DV-150i 6" x 6" Centrifugal 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.
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.
