Alfa Laval SCPP


The Alfa Laval SCPP consists of two positive displacement pump ranges engineered specifically for transporting low viscosity fluids at elevated discharge pressures.

  • Ideal for low viscosity liquids at elevated discharge pressure
  • A variety of models that meet a wide spectrum of various pressures
  • Deep channels in rotors to minimize shear on solids


The SCPP pumps have large inlet and outlet ports, to help reduce pressure losses as products enter the pump. This design, combined with circumferential piston pump technology delivers reduced net positive suction head required (NPSHr). The result is considerably reduced risk of cavitation and subsequent pump damage.


Tight clearances between rotor and rotorcase decrease slip when pumping low viscosity liquids at higher discharge pressures. This improves volumetric efficiency on low viscosity liquids and helps reduce flow rate variance under variable backpressures.


The SCPP pump comes standard with twin-wing rotors in a non-galling alloy material, which are applicable for most pumping applications. If the fluid to be pumped contains large solids, the option of a single-wing rotor is available.

Alfa Laval SCPP Benefits

Direction of flow is reversible

The deep channels in which the rotors travel create large voids to minimize shear of solids

Minimizes deflection even at high discharge pressures

Ideal for strip-clean applications

Enhanced CIP options

Operating Principles

Rotor wings (pistons) rotate around the circumference of the channel in the pump casing. This constantly generates a partial vacuum at the suction port as the rotors unmesh, triggering fluid to enter the pump. The fluid is transported around the channel by the rotor wings, and is displaced as the rotor wings re-mesh, generating pressure at the discharge port.


Rotors for the Alfa Laval SCPP are made of non-galling alloy, allowing close clearances between rotating and stationary surfaces, resulting in less slip and increased efficiency for pumping low viscosity fluids at higher discharge pressures.
