The Alfa Laval SX Rotary Lobe Pump is designed with optimised pump head geometry and multi-lobe rotors to ensure low-shear operation with minimum pulsation. This makes the SX the best choice for maintaining the integrity of delicate products.
The pump is designed according to the most stringent hygienic design standards and with verified, effective Cleaning-in-Place (CIP) and Sterilisation-in-Place (SIP).
For another pump in the Alfa Laval SX series, see the SX UltraPure.

The SX Rotary Lobe pump is designed for gentle transportation of process fluids in hygienic and ultra-clean applications in the biotechnology and pharmaceutical industries, in the home and personal care sector, and for demanding food applications. It is available with 14 different pump head displacements based on seven different gearbox modules to handle flow rates up to 115 m3/h and differential pressures up to 15 bar.
A gear train in the pump gearbox drives and accurately synchronises rotors. The movement of the counter-rotating rotors creates a partial vacuum that allows atmospheric pressure or other external pressures to force fluid into the pump chamber. As the rotors revolve, and the blades disengage, an expanding cavity is formed that fills with fluid. When the blades reengage, the cavity diminishes and this fluid is displaced into the outlet port.
