Plastic Air-Operated Double Diaphragm Pumps

Find a huge selection of Plastic Air-Operated Double Diaphragm Pumps from China at Dongkai. The Plastic Air-Operated Double Diaphragm Pumps is a new type of pumps. In recent years break-through progress has been made in the diaphragm material, so more and more industrialized countries in the world have adopted such a pump type to replace some centrifugal or screw pumps to be applied in such industries as petrochemicals, ceramics and metallurgy. Plastics Electric diaphragm pump are applicable for low pressure applications, namely the outlet pressure ≥3kgf/cm2.

Product Description

Dongkai is a leading China Plastic Air-Operated Double Diaphragm Pumps manufacturers.

1. Product Introduction of Plastic Air-Operated Double Diaphragm Pumps

Our plastic modular design Because they are made of PE, PTFE, PP, or PVDF, electric diaphragm pump housings are resistant to practically all chemicals. Particularly delicate material distribution is made possible by the pump technology because of the smooth diaphragm surface. As a result, these double diaphragm pumps are particularly robust and can be operated at temperatures from -40°C to +120°C. In addition, delivery pressures of up to 6.0 bar are possible. Viscous media up to max. 20,000 mPas are easy for our electromechanical double diaphragm pumps.

2.Product Parameter (Specification) of Plastic Air-Operated Double Diaphragm Pumps

DBY is new developed series of Dongkai pump which is also the third generation, it has the virtue of long service life and nonstop operation, not only it can convey some uneasy flowed medium, with the merits of self pumping pump, diving pump, shield pump, slurry pump and impurity pump etc.
Features
1. it is unnecessary to pour the drawing water, the suction lift reaches 6m height, the delivery lift reaches 70m length.
2.wide flow and good performance. the diameter allowed to pass the max grain reaches 10mm, the damage is very less to the pump while exhausting the slurry and impurity.
3.the delivery lift and flow can pass the pneumatic valve open to realize the step less adjustment( the pneumatic pressure adjust ment is between 1-8 bar)
4. the diaphragm separates the working medium from the pump is moving parts compeletely, so the medium will not leak outside. it will not result in environmental pollution or endanger personal safety when transportng toxic, volatile or corrosive media.
5. no electricity. it is safe and reliable while using in the flammable and explore places.
6. it can be soaked in medium
7.it is convenient to use and reliable to work. only open or close the gas valve body while starting or stopping. even if no medium operation or pausing suddenly for long time because of accident matters. the pump will not be damaged caused by this once over lading . the pump will automatically stop and possesses the self protection function. when the load recovers normallly. it also can start automatically
8.simple structure and less wearing parts. this pump is simple in structure, installation and maintenance. the medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever etc. not like other kinds pumps, the performace will drop gradually because of the damages of rotor., gear and vane etc.
9. it can transmit the adhesive liquid( the viscosity is below 10000 centipoises)
10. This pump doesn't require an oil lubrication, nor does it affect the pump in any way. This is a feature of the pump.
