Working Principle
In the two symmetrical working chambers of the pump, each is equipped with an elastic diaphragm, and the connecting rod integrates the two diaphragms. After the compressed air enters the center body from the inlet joint of the pump, it pushes the diaphragms in the two working chambers and drives the diaphragms connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged from the pump through the back of its diaphragm. When the piston reaches the end of its stroke, the valve automatically directs compressed air into the other chamber, pushing the pump in the opposite direction, thus creating a synchronous reciprocating motion between the two diaphragms. Each working chamber is provided with two one-way ball valves, the reciprocating movement of the diaphragms causes the volume of the working chamber to change, forcing two one-way ball valves alternately open and close, so that the liquid is continuously sucked in and discharged.
Features
1. The pump body is made of sanitary stainless steel to meet the requirements of high hygiene level operations;
2. The pump body has been polished, the whole pump has no dead point and the material is not easy to remain;
3. Adopt clamp quick connection, which is easy to disassemble and clean;
4. No need for irrigation water, suction height is up to 5.48 m, head isup to 84 m, outlet pressure ≤ 0.84 Mpa;
5. Low shear rate. Max. permitted grain diameter is 6.4 mm. There is little wear when pumping material containing particles;
6. Head and flow rate can be adjusted by air source pressure (air source pressure is between 0.1-0.84 Mpa);
7. Operating temperature range: 5-65ºC, liquid temperature range:(- 20ºC-150ºC);
8. Structural explosion-proof, safe and reliable in flammable and explosive places;
9. Easy to use, reliable operation, start and stop only need to simply open and close the gas valve, even idling or outlet blockage, the pump will not be damaged. Once overloading, the pump will stop automatically, with self-protection performance, and when the load is restored to normal, it can start the operation automatically;
10. Simple structure, less vulnerable parts, easy to install and maintain. The material transferred by pump will not touch the moving parts such as the air distribution valve and connecting rod, unlike other types of pump performance will gradually decline due to the wear of rotor, piston, gear, blade and other parts;
11. It can transfer viscous liquid (The viscosity is less than 10000 cps).
