Technical documentation

These pumps are used in cases where:
- the liquid being dosed contains a small amount of suspended solids;
- the liquid being dosed is toxic;
- liquid leakage is unacceptable

A built-in safety valve is installed in the hydraulic circuit to protect the diaphragm from excessive pressure.

A special feature of this pump is a special three-layer diaphragm and a reliable diaphragm rupture detection system.

Each pump is equipped with a standard gearbox system and a vertically positioned B14 electric motor, profiled according to UNEL-MEC specifications.

The motor power range is from 0.18 kW to 0.75 kW.

A selection of alternative options is available, including different voltages, insulation classes and special explosion-proof versions.

The gearbox has a standard endless screw and wheel worm type, equipped with bearings completely immersed in oil.

The stroke length change mechanism is a positive direct stroke, spring return type, which is actuated by an eccentric.
