Corrosion resistant and wear resistant
Special materials with high corrosion resistance and wear resistance are used for the body and chamber of the pump.
Easy to maintain with low cost
No need to open the pump body in order to change diaphragm and valve.
High pressure & High efficiency
Motor efficiency could be as high as 85% and pressure could be 0~150kgf/cm².
Low nosy and low ripple
Smooth operation due to multi-plunger structure. Additionally, oil pressure drive diaphragm can control the pulse and maintain low noisy.
User-friendly
Defects related shaft sealing can be avoided due to o seals in this pump and no water exhaling due to effective self-suction. The bilateral rotation of the pump shaft makes it easy for operation.
To deliver slurry containing fine particles, such as dye slurry, paint slurry, etc. so as to match high pressure granulation equipment, etc.
Reverse osmosis membrane pressurized water delivery equipment and matching valve pressure test equipment of sea water desalinating unit, ultra pure water preparation equipment, etc.
To convey sludge to pressure filter, inhale sludge from or convey sludge to gas explosion groove.
High pressure cooling liquid of deep-hole drilling machine and machining centre for deep-hole processing or ceramic grinding.
The cleaning of precision machining components, printed circuit board and post processing of burr.
The swill of food factory conveyor belt or machine; high-pressure cleaning of ships or vehicles.
To convey high tricky liquid, such as glue, adhesive, jam, wheat paste, cream, etc.
Operation Principle
1. The following diagram is showing the structure of multi-plunger high pressure diaphragm pump. The pump body consists two parts: A oil room full of lubricating oil B pump room of pressurized liquid delivery. The oil room and pump room are separated by diaphragm ⑤ , and there is no drive device or seal device producing friction in the pump room.
2. Along with the rolling of the pump shaft ⑩ , ball transfer unit ⑨ on the eccentric shaft is driven by the gear and pushes four plungers ⑧ in turn, then the oil pressure in plunger barrel ⑦ is increased to make diaphragm heave towards pump room. Meanwhile, plunger springs ⑥ in other plungers push the plunger back, diaphragm is also pulled back towards the oil room.
3. The liquid is absorbed through the Suction Mouth on the end of pump cover ① and separated into four parts by the rooms formed by valve plate ② , valve ③ , valve seat ④ and four diaphragms. The capacity of the room is expanded or reduced with the reciprocating movement of the diaphragm, the two valves positively and negatively installed open and close in turn to make the liquid flow to certain direction and then confluent out from the outfall on the pump cover.
