Standard Design

Pump Gearbox

The OptiLobe pump range has a universal gearbox design with the flexibility of mounting 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

TheOptiLobepumprangehashygienic 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 130°C facilitating use with CIP processes.

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.
