A250

Technical features:

Plunger metering pumps are suitable in case that:
- The dosed liquid is a non abrasive solution
- A drip proof system is not essential
- High pressure is required
Each pump is fitted with 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 0.75 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 available alternative options, including different voltages, insulation classes and special explosion proof versions.
The reduction gearbox is of a standard endless screw plus worm-wheel type, supported by bearings, fully lubricated in an oil-bath.
The mechanism for variation of the stroke length is a positive fore-stroke, spring return type, that is operated by an eccentric

Spring Return Mechanical Diaphragm Pump - type D

Mechanical Diaphragm pumps are suitable in case that:

The dosed liquid contains small amounts of suspended solids
The dosed liquid is a toxic solution
A drip proof/air tight application is required
High pressure is not required

Pump Type	Capacity (max)	Pressure (max)	Motor kWt	Weight net kg (max)
D-050U	49 l/h	10 bar	0,18	12
D-100U	374 l/h	5 bar	0,18	14
