Mechanical Diaphragm pumps are suitable for use when:
The dosed liquid contains small amounts of suspended solids
The dosed liquid contains a toxic solution
A drip proof/airtight application is required
High pressure is not required
Each pump is fitted a standard gearbox reduction system and with a vertical mounted B14 shaped electric motor in accordance with UNEL-MEC specifications
The motor power range is from 0.18 Kw up to 0.37 KW as the European standard: 3 phase voltages of 230/400V @ 50/60Hz, 4 pole and 1 phase voltages of 230/50/60 Hz or 110/60 Hz
As motors conform to UNEL-MEC specifications, there are many alternative option available, including different voltages, insulation class and special explosion proof versions
The gearbox is a standard worm wheel reduction system with all bearings supported within a fully lubricated gearbox
The mechanism for variation of the stroke length a positive stroke spring return that is operated by an eccentric
