A type in a special structure of positive displacement pumps
An electric diaphragm pump, a type in a special structure of positive displacement pumps, is composed of mechanical drive and diaphragm pump head.
PTFE diaphragms through special compression moulding feature good mechanical performance and resistance to corrosion by strong acids, bases, acids and solvents.
Pump advantages
Check valve assembly resistive to bonding and precipitation allows fluid transport of high viscosity and with particles generating little vibration or noise.
Suction of high-temp liquids below 150℃;Enhanced-strength four-diaphragm assembly with highly sensitive and reliable pressure conduction or on-off.
Alarm function
Alarm can realize local display, signal output and pump safety running monitoring all the time.Over-pressure protection avoids pump stop in case of accidental pipeline blocking or fluid discharge under zero stroke length.

Complete Guide
Electric Diaphragm Pump DPD80-20-50-III
Working principle, The motor drives worm gear pair, changes rotary motion of the motor into reciprocating movement of the slide rod through the eccentric mechanism, the slide rod drives the mechanical diaphragm to perform periodical deformation, thus realizing fluid suction and discharge.
Max Discharge Pressure:95 MPa;Max Discharge Flow Rate per Pump Head: 12100 L/h;Flow rate can besteplessy adjusted in the range of 0-100%'Metering accouraoy reaches ±0.5%;
A pump head can be made of 304, 316, 316L, 904, Hastelloy C, PVC, PVDF, PP, PTFE, etc.
