These pumps are used when:
- the liquid being dosed contains a small amount of suspended solids;
- the liquid being dosed is toxic;
- a drip-proof/tight design is required.
Each pump is equipped with a standard gearbox system and a vertically positioned B14 electric motor profiled in accordance with the specifications.
The motor power range is from 0.18 kW to 0.75 kW in accordance with the European standard: 3 phases 230/400 V 50/60 Hz, 4 poles and 1 phase 230/50-60 Hz or 110/60 Hz.
As the motors meet the technical requirements of UNEL-MEC, there are many alternative options available, including different voltages, insulation classes and special explosion-proof designs.
The gearbox has a standard endless screw and worm wheel, with bearings completely immersed in oil.
The stroke length change mechanism is a positive direct stroke, spring return type, which is driven by an eccentric.
