Hydraulic diaphragm metering pumps

Release Time:

Jan 23,2024

the hydraulic end of the pump with the help of a diaphragm to form a working cavity and replaces the reciprocating motion of the piston (plunger) with the periodic deformation of the diaphragm is called a diaphragm pump. For example, the periodic deformation of the diaphragm is a hydraulically driven pump that reciprocates in the hydraulic working cavity with the help of a piston, which is called a hydraulic diaphragm pump.

A pump that defines
the hydraulic end of the pump with the help of a diaphragm to form a working cavity and replaces the reciprocating motion of the piston (plunger) with the periodic deformation of the diaphragm is called a diaphragm pump. For example, the periodic deformation of the diaphragm is a hydraulically driven pump that reciprocates in the hydraulic working cavity with the help of a piston, which is called a hydraulic diaphragm pump.
Features
1. No dynamic seal, no leakage, easy maintenance;
2. The working pressure can reach 69MPa, and the measurement accuracy can reach ±1%; Flow range of single cylinder pump: 0.2Lh- 12000L/h
3. The metering accuracy is better than that of the mechanical diaphragm pump, and the sealing performance is better than that of the piston pump;
4. The flow control is realized by adjusting the stroke length and frequency conversion speed regulation, and remote automatic control can be realized with stroke regulator or frequency conversion;
5. The use temperature of the medium should not exceed 100% C, and should not be lower than 30C, otherwise the life of the diaphragm will be affected;
6. The application of the new three-valve structure and the limit oil replenishment mechanism not only ensures the fullness of the hydraulic oil in the hydraulic cavity, but also avoids excessive oil replenishment and prevents hydraulic impact, so that the force on both sides of the diaphragm is balanced, and the service life of the diaphragm can be increased to more than 8000h;
7. When conveying special media, double diaphragm with diaphragm rupture alarm device can be used to prevent accidents caused by mixing medium and hydraulic oil when the diaphragm is ruptured.
The application
is suitable for general normal temperature water until it has strong corrosion, volatile, easy crystallization, flammable, explosive, highly toxic, foul smell, strong corrosiveness, heavy weight, medium viscosity, radioactive or other precious liquids. At the same time, it can also transport suspended liquid, for some in order to prevent the diaphragm from rupturing, the medium and hydraulic oil are mixed to cause accidents, and when flammable and explosive, highly toxic and valuable liquids, a double diaphragm metering pump can be selected with a diaphragm rupture alarm device.
