Delta Solenoid-Driven Diaphragm Metering Pumps Get latest price

A range of different pump types and material combinations are available for virtually all metering applications. The optional 1-month process timer offers a variety of installation options.

The pump achieves maximum precision even with fluctuating back pressure thanks to the regulated solenoid drive. This guarantees an exceptionally long service life even under maximum load. The integrated monitoring function opto Guard^® reports faulty hydraulic conditions, such as overpressure or ruptured metering line.

The large illuminated LC display guarantees excellent legibility of all displayed values. The capacity is shown directly in l/h.

• They can be used in all industries and integrated into automated processes. Maximum process reliability through the regulated solenoid drive and opto-Guard^® monitoring function.
• The pump can work as a control unit with the process timer, for example in cooling water treatment

• Adjustment of the capacity directly in l/h
• Adaptation to existing signal transducers by external control via potential-free contacts with pulse step-up and step-down

• Capacity range 7.5 – 75 l/h, 25 – 2 bar
• External control via 0/4 – 20 mA standard signal with adjustable assignment of signal value to stroke rate
• External control via potential-free contacts with pulse step-up and step-down to adapt to existing signal transducers of 99:1 to 1:99
• Batch operation with max. 65,536 strokes/start pulse
• Stroke rate adjustment in 1 stroke/hour steps of 0 to 12,000 strokes/h and/or 200 strokes/min
• Stroke length continuously adjustable between 0 – 100% (recommended 30 – 100%)
• Connector for 2-stage level switch
• Dosing monitor input with adjustable number of tolerated defective strokes
• Optional optical diaphragm rupture indicator detects droplets behind the diaphragms
