Versatility

Different diaphragm sizes are available to suit different applications, starting from 4 until 574 l/h

Reliability

The high degree of accuracy and reproducibility with high quality materials selected make the mechanical diaphragm SR series to assure the maximum reliability.

Quality

The best performance for the applications is achieved by optimal selection of material and diaphragm design

1. 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/air tight application is required
• High pressure is not required

2. Each pump is fitted a standard gearbox reduction system and with a vertical mounted B14 shaped electric motor in accordance with UNEL-MEC specifications.

3.The motor power range is from 0.18Kw 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.

4.As motors conform to UNEL-MEC specifications, there are many alternative option available, including different voltages, insulation class and special explosion proof versions.

5.The gearbox is a standard wormwheel reduction system with all bearings supported within a fully lubricated gearbox.

6.The mechanism for variation of the stroke length a positive stroke spring return that is operated by an eccentric.

PUMPING HEADS

Pumping heads are made in standard executions: S.S. 316, PVC and PP. A wide range of other materials like HASTELLOY, ALLOY, PTFE, PVDF are according to the liquid to be dosed. Standard liquid handled maximum temperature

• 60° C with S.S. 316 pump head
• 40° C with PVC pump head

Jacketed pump head for either cooling or heating are available to suit requirements.

MULTIPLE HEADED PUMPS

Different multiple heads units are available on request. Each pumping element has independent adjustment while running or at standstill. “D” series Mechanical Diaphragm pumps are available in different sizes:

• D 50 N Stroke lengh 5 mm
• D 100 N Stroke lengh 10 mm
• D 101 N Stroke lengh 10 mm
• D 121 N Stroke lengh 12.50 mm

For these four types, different diaphragm sizes are available to suit different applications for capacity and pressure.
