Each pump is built with a standard gearbox reduction system and a vertically mounted B14 shaped electric motor in compliance with UNEL-MEC specifications.

Motor power is usually 0,09 Kw with single and three phase voltages available.

There are many available options including different voltages, insulation classes and special explosion proof versions.

The reduction gearbox is a standard endless screw plus worm-wheel type, supported by bearings, fully lubricated in an oil-bath.

The mechanism for the variation of the stroke length is a positive fore-stroke, spring return type, that is operated by an eccentric; this makes the diaphragm move forward (discharging phase) for all the stroke length, while the spring in continuous tension causes the comeback of the diaphragm (suction phase).
