Series PC Transfer pump

PC Transfer pump

Progressing cavity process pump, compact for space saving. For pumping wastewater sludge, effluents and shear sensitive fluids in municipal and industrial process applications.

Construction

Materials of construction, available in cast iron or stainless steel, with a choice of rotor and stator materials to suit individual applications e.g. hard chrome plated rotor or natural rubber stator.

Applications

Typical applications for the PC transfer pump include:

  • Municipal and Industrial effluents
  • Sludge transfer processes
  • Shear sensitive processes
  • Hydrated lime slurry
  • Industrial chemicals and detergents
  • Paper stocks
  • Starch slurries
  • Ground water with manganese
  • Agricultural effluent and farm waste slurries

Features

  • As the drive forms an integral part of the unit, the pump is ideal for space-saving installations.
  • Gentle pumping action, minimises shear and crush damage to the pumped product.
  • Surface mounted, making it easier, cleaner and less hazardous for maintenance.
  • Up to 8.5 m suction lift, deep sumps can be easily pumped.
  • Plug-in shaft, ease of maintenance when assembling or dismantling, with extraction facility.
  • Viscous fluid products can be supplied with a square inlet and conveyor to assist viscous slurries into the pumping element.
  • Inspection cover, available for applications where known rag content is a problem.
  • Supplied with a baseplate to ease installation, or option without baseplate.
  • Sealed joints, fully sealed drive train to maximise life and minimise downtime.
  • Shaft sealing options, packed gland or single and double mechanical seals are available.
  • Versatile, can be installed vertically or horizontally to suit the application. Can be run in either direction.

Motor / drives

  • Robust drives, specially selected drives and gearboxes for longer life. Options include electric motor drive units supplied as direct-coupled or variable speed drives with mechanical variable speed or frequency inverter.
  • Low running speeds, reduced wear for a longer working pump life which extends the periods between routine maintenance. Important in abrasive applications.

Performance

Capacity, for flows up to 440 m3/h and differential pressure up to 24 bar, to operate in a range of process temperatures from -10 °C, up to 100 °C.

Performance data

 

m3/h = capacity. Bar = differential pressure.
