Series PC Cake pump

PC Cake Pump

Progressing cavity process pump, designed for pumping of highly viscous materials such as sludges, slurries, thick non-flowing pastes and dewatered sludge cake, 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 cake pump include:

  • Heavy sludge cake transfer for greater than 30% dry solids concentration.
  • Dewatered and thickened sludge transfer.
  • Sludge blending.
  • Imported and organic waste sludge transfer.
  • Industrial process sludge with high percentage dry solids concentration.

Features

  • An auger screw conveyor for efficient feeding of the pump when handling high percentage dry solid sludge concentrations.
  • Gentle pumping action, minimises shear and crush damage to the pumped product.
  • Supplied with a baseplate to ease installation, or optional without.
  • Fully sealed drive train to maximise life and minimise downtime.
  • Hard faced, single mechanical seal as standard, with packed gland as an option.
  • Designed to accommodate optional hopper or bridge breaker attachments.

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 heavy cake applications.

Performance

Capacity, for flows up to 49 m3/h and differential pressure up to 24 bar, to operate in a range of process temperatures from -10 °C, up to 100 °C
