DV-200c 12" x 8" 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 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.
