High Pressure Air Operated Diaphragm Pump Resolve Numerous Problems
Air Operated Diaphragm Pump Introduction
Pneumatic Diaphragm Pump are machines for conveying or pressurizing
fluids. The pump is mainly used to transport water, oil, acid and
alkali liquid, emulsion, suspending emulsion and liquid metal, and
also can transport liquid, gas mixture and liquid containing
suspended solids. Pumps can generally be divided into three types
according to their working principles: volumetric pumps, power
pumps and other types of pumps. According to the driving method, it
can be divided into electric pump and water wheel pump,
single-stage pump and multi-stage pump according to the structure,
boiler feed pump and metering pump according to the use, and water
pump, oil pump and mud pump according to the nature of liquid
delivery. According to the shaft structure, it can be divided into
linear pump and traditional pump. Pumps can only transport fluid as
the medium of logistics, not solid.
Air Operated Diaphragm Pump Advantage
1. No irrigation water, suction up to 5 meters, head up to 70
meters, the outlet pressure > 7bar
2. Wide flow and good performance, which allows the maximum
particle diameter of 10 mm. Pumping mud, impurities, minimal wear
and tear on the pump
3. Head, flow through the valve open to realize the stepless
adjustment (pressure regulator between 1-7bar)
4. The pump has no moving parts, no seals, diaphragms exhausted
medium and pump running parts, working medium is completely
separated from the transmission medium does not leak out. So
pumping toxic, volatile or corrosive media, will not cause
environmental pollution and danger to personal safety.
5. Do not have electricity, flammable and explosive places safe and
reliable.
6. Can be immersed in the medium.
