SSP super heavy duty rotary lobe pumps from Alfa Laval are excellent pumps for highly viscous applications. High efficiency, low energy consumption smooth flow and able to handle abrasive media are some of the benefits to mention.

Rotary lobe pumps can handle solids (e.g., fruit pieces and meat cubes), slurries, pastes, and a variety of liquids. A gentle pumping action minimizes product degradation. Special models are available for highly abrasive liquids, aggressive chemicals, or shear sensitive liquids.
Rotary lobe pumps offer continuous and intermittent reversible flows and can operate dry for a brief period, only if flushed seals are used. The flow is relatively independent of changes in process pressure, too, so output is constant and continuous.

The Series S pump range has twelve pump head displacements ranging from 1.4 gallons/100 revs to 93.26 gallons/100 revs.

  • Flow rates up to 466 gpm
  • Differential pressures up to 290 psi
  • Port sizes from 1″ to 6″ diameter

High Volumetric Efficiency – The Series S pump offers high efficiency transfer of low, medium and high viscosity pumped media. This important aspect of performance is achieved by maintaining high accuracy and repeatability of component part manufacture, thereby maximizing shaft rigidity and minimizing the effects of thermal expansion within the pump gearbox. This combination allows the optimum pump head geometry to be achieved which, in turn, maximizes volumetric efficiency.
Low NPSH – The Series S pump with standard port connections has full through-bore inlet and outlet ports to International Standards. This reduces inlet and outlet port losses, thereby lowering NPSH requirements.
