Alfa Laval SX Series Pumps

Built from the ground up for hygienic applications, the SX is Alfa Laval’s premium rotary lobe pump. Designed for gentle transportation of process fluids, it's perfect for hygienic and ultra-clean applications in the biotechnology and pharmaceutical industries, health and beauty, and demanding food applications.

With the SX's multi-lobe rotor geometry, it offers low pulsation and gentle pumping. This makes it the best choice for transporting sensitive products that require gentle handling to minimize shearing.

This EHEDG-approved pump is designed for both Clean-in-Place (CIP) and Sterilization-in-Place (SIP).

Applications

The SX range of rotary lobe pumps has been designed for use on a wide variety of applications within the pharmaceutical, biotechnology, fine chemical, and speciality food industries. Being certified by EHEDG (European Hygienic Equipment Design Group) as fully CIP'able to their protocol, the SX range is ideally suited to applications where cleanability and corrosion resistance is paramount.

In addition, the SX pump range also conforms to USA 3-A sanitary standards and all media contacting components are FDA compliant. The SX pump operates with a high efficiency, low shear pumping action for assured gentle handling of delicate and sensitive media.

The SX pump range is also classified for use in potentially explosive atmospheres under the ATEX Directive 94/9/EC Group II, Categories 2 & 3, with temperature classification T1 to T4.

The SX range is compact in size, and can handle flow rates up to 506 gpm and pressures up to 218 psi.

Pump Gearbox

The SX pump, with its conventional lobe pump design concept has a robust cast iron gearbox, which provides maximum shaft rigidity and easy oil seal replacement. The SX range in series 1 – 4 has a universal gearbox design. This gives the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal plane, by changing the foot and its position.

The SX range in series 5 & 6 has dedicated gearbox castings, which also allow the inlet and outlet ports to be in either the vertical or horizontal plane. The SX series 7 has a dedicated gearbox casting allowing inlet and outlet ports in a vertical plane only.

Pumphead Construction

The SX pump has sanitary design full bore inlet and outlet ports to International Standards, maximizing inlet and outlet port efficiency and NPSH characteristics. Vertical porting and unique rotorcase internal profile enhances self-draining and self-venting while maintaining optimum volumetric efficiency.

The SX pump has four lobe rotors, designed using CFD (Computational Fluid Dynamics) to develop the optimum rotor geometry - possibly the first rotary lobe pump to be developed using this technology. All rotors are rated to 302°F facilitating use with CIP/SIP processes.

Pump Sizing

To correctly size a rotary lobe pump some essential information is required. Provision of the information listed below enables our customer support personnel to determine the optimum pump selection:

  • Fluid to be pumped
  • Viscosity
  • SG/Density
  • Pumping temperature — minimum, normal, and maximum
  • CIP temperature(s) — minimum, normal, and maximum

MATERIALS
Pump GearboxHigh quality grey cast iron
PumpheadProduct wetted components in 316L
Product Wetted Elastomers*EPDM, MVQ, FPM
Mechanical Seals**Carbon/Stainless Steel

*Product wetted elastomers are FDA conforming. All media contacting elastomers are controlled compression joints, the latest technology where static and dynamic elastomer seals are used to prevent pumped media leaking to atmosphere.

**Variations of these materials are available to suit fluid being pumped and/or application requirements. The seal seat and face material combinations are all EHEDG compliant.

Shaft Seal Options
  • Single or single flush/quench (steam barrier for aseptic application) R00 type mechanical seals
  • Double R00 type mechanical seal for flush.

All sealing options are fully front loading and fully interchangeable without the need for additional housings or pump component changes. Specialized seal setting of the mechanical seal is not required as the seal is dimensionally set on assembly. This feature further enhances fast and efficient on-site seal interchangeability.

Standard Specification Options
  • Tri-Clamp® inlet and outlet ports standard
  • Screwed male inlet and outlet ports to DIN11851, SMS, ISS/IDF or RJT or Tri-Clamp
  • Heating/cooling jacket for Rotorcase cover
  • Electropolished product wetted components
  • Complete pump unit comprising: Pump + stainless steel baseplate + coupling with guard + geared electric motor, suitable for (or supplied with) frequency speed control or manual variable speed drive (advise motor enclosure and electrical supply)
  • Full material traceability on request to EN 10204 3.1
