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.
