DV-80c 4" x 3" 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.
