HH-150 8" x 6" High Head 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 1.5”
(38mm) diameter.
The impeller is of a fully open design with balance holes
and back pump out vanes. The pump utilizes a three vane
impeller design for pumping under most conditions. The impeller
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 pump casing
fitted with 316 Stainless Steel or 2% chromium steel alloy
(340 BHN) impeller and wear plates; complete 316 Stainless
Steel wet ends; complete CD4MCu wet ends; or complete chromium
alloy wet ends.
Guards are fitted as standard to all moving parts.
