• This reduces the risk of process contamination, whilst improving product quality.

• Front cover o-ring not profiled on cusps or rotor bore, which is unhygienic.

• O-ring groove is square-cut into front cover. Apparent poor finish will create bug trap.

• Exchangeable position 02 rotor and easy to replace new rotors.

• Rotors marked “0” and “1”, corresponding to marks on shaft spline for positional assembly. Difficult to see when maintaining pump in site.

• 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.

• Gearbox is not universal. Vertical porting option is only possible if using a different gear case.

• allow for 20,000 hours minimum pump operation before replacement
• optimised axial load transmission
• reduce pump maintenance cost
• increase process up-time
• increase pump life-time

• Shafts were held in a “cartridge assembly”
• Timing gears located between front & rear bearings. Front bearing (not visible) is single ball bearing on all models – very weak design, suitability on arduous duties questionable!!

• One piece bearing housing gives stable shaft retention within rigid construction providing for greater pump durability under operation, extending pump life-time

• pump build repeatability
• consistent pump performance, leading to simplified pump servicing, reduced process down-time and less process variance

• Component interchange-ability questionable.
• Requirement for either new rotor, shaft or sleeve will mean pump clearances must be reset.
• Rotor nuts come off easily.
