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.
