Diaphragm pump drive mode : motor drive and air drive

EODD Electric double diaphragm pump-PVDF-65
AODD-50-65-PP Air Operated Double Diaphragm Pump
AODD-50-65-PP Air Operated Double Diaphragm Pump


Air Operated Diaphragm Pump Characteristics:

1. Compressed air as power.

2.  Is a positive displacement pump caused by the reciprocating deformation of the diaphragm volume change, its working principle is similar to the plunger pump, because of the characteristics of the working principle of diaphragm pump, diaphragm pump has the following characteristics:

(1) pump will not overheat: compressed air for power, in the exhaust is an expansion of heat absorption process, pneumatic pump working temperature is reduced, no harmful gas discharge.

(2) no electric spark: Air Operated Diaphragm Pump does not use electricity for power, after grounding and prevent electrostatic spark

(3) Can be through the liquid containing particles: because the positive displacement work and the inlet is a ball valve, it is not easy to be blocked.

(4) Extremely low shear force on materials: how to suck in and how to spit out when working, so the minimum agitation of materials, suitable for the transport of unstable substances

(5) The flow can be adjusted. The throttle valve can be installed at the outlet of the material to adjust the flow.

(6) It has the function of self-priming.

(7) It can run empty without any danger.

(8) Can work under water.

(9) An extremely wide range of fluids can be transported, from low viscosity to high viscosity, and from corrosion to viscous.

(10) No complex control system, no cables, fuses, etc.

(11) Small volume, light weight, easy to move.

(12) No lubrication is needed, so it is easy to maintain, and the working environment will not be polluted by drip leakage.

(13) Pump can always maintain high efficiency, will not be reduced because of wear.

(14) 100% energy utilization. When the outlet is closed, the pump will automatically stop, and the equipment will be moved, worn, overloaded and heated

(15) No dynamic seal, easy maintenance to avoid leakage. No dead point at work


Electric Operated Diaphragm Pump Characteristics:

1. No irrigation and water diversion is required, and the self-absorption capacity is more than 7 meters.

2. through the performance is good, the diameter of less than 10 mm particles, mud, etc. can pass effortlessly.

3. Because the diaphragm will be delivered medium and drive mechanical parts separate, so the medium will never leak outward. And pump itself without shaft seal, the service life is greatly extended. According to different media, the diaphragm is divided into neoprene, tetrafluoroethylene, butadiene rubber, teflon, etc., which can completely meet the requirements of different users.

4. Small volume and light weight: due to the use of planetary cycloid transmission structure, so that the pump to obtain small size, if compared with the same type of pump, its volume and weight are reduced by half.

5. Pump body medium flowing through part, according to user requirements, divided into cast iron, stainless steel, PP,PVDF,PDFE, motor divided into ordinary type, explosion-proof type, speed regulating type.
