OptiLobe Rotary Lobe Pump

Application
Opti1The OptiLobe range of rotary lobe pumps combines cost-effective simplicity with Alfa Laval quality and reliability. The OptiLobe range has been developed for general applications within the Dairy, Beverage and Food Industries.
The OptiLobe pump range has been certified by EHEDG (European Hygienic Equipment Design Group) as fully CIP cleanable to their protocol, and therefore is ideally suited to applications where cleanability is paramount.
Also the OptiLobe pump range conforms to USA 3-A Sanitary
Standard and all media contacting components are FDA compliant.
The pump features the "EasyFit" front loading seal which allows quick and easy inspection or replacement without the need for pipework disassembly.
The OptiLobe pump range is compact, efficient and capable of flow rates up to 48 m/h and pressures up to 8 bar.
 
Standard Design
 
Pump Gearbox
The OptiLobe pump range has a universal gearbox design which gives the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal plane by simply changing the foot position.
A stainless steel gear canister and electro-less nickel plated bearing housing provides a clean, paint free corrosion resistant external finish.
 
Pump head Construction
The OptiLobe pump range has sanitary design full bore inlet and outlet ports to International Standards, maximising inlet and outlet port efficiency and NPSH characteristics. Pumps are fitted with tri-lobe rotors rated to 130C facilitating use with CIP processes.
 
Materials of Construction
Gear canister - 304 stainless steel. Bearing housing - electroless nickel plated cast iron. Shafts - duplex stainless steel.
Pumphead - product wetted components in 316L .
Product wetted elastomers of EPDM, FPM all FDA conforming.

Shaft Seal Options
- EasyFit type single or single flush/quench mechanical seals.
All sealing options are fully front loading and fully interchangeable.
Specialised 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.

Materials for Mechanical Seals
Carbon/Stainless Steel, Carbon/Silicon Carbide or Silicon Carbide/Silicon Carbide.
 
Pump Sizing
In order to correctly size a rotary lobe pump some essential information is required. Provision of this information listed below enables our Customer Support personnel to obtain the optimum pump selection.
 
Product/Fluid Data
- Fluid to be pumped
- Viscosity
- SG/Density
- Pumping temperature, minimum, normal and maximum
- Cleaning in Place temperature(s), minimum, normal and maximum
 
Performance Data
- Flow rate, minimum, normal and maximum
- Discharge head/pressure (closest to pump outlet)
- Suction condition
 
Standard Specification Options
- Specification of inlet and outlet ports (Screwed male to DIN11851 to BS 4825, SMS, ISS/IDF, RJT and Tri-clamp).
- Complete pump unit comprising: Pump + Baseplate (mild or stainless steel) + 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)
 
Working Principle
The positive displacement of the OptiLobe pump is provided by non-contacting, contra rotating tri-lobe rotors within a fully swept pump chamber. All OptiLobe pumps are capable of bi-rotational flow without modification.
