A diaphragm metering pump is a device used to accurately measure liquids. It uses a specially designed diaphragm to perform reciprocating motion to complete the liquid suction and discharge process. It is widely used in the chemical, pharmaceutical, food, environmental protection and other industries, and has become the main pump type in fluid metering applications.
A diaphragm metering pump is a device used to accurately measure liquids. It uses a specially designed diaphragm to perform reciprocating motion to complete the liquid suction and discharge process. It is widely used in the chemical, pharmaceutical, food, environmental protection and other industries, and has become the main pump type in fluid metering applications. Diaphragm metering pumps can achieve accurate metering of liquids, and according to different process requirements, they can also be customized to add additional functions such as pulse damping and magnetic drive, thereby improving production efficiency and product quality.
The main types of diaphragm metering pumps: Mechanical diaphragm metering pumps, Electromagnetic diaphragm metering pumps and Hydraulic diaphragm metering pumps.
The motor drives the worm through the coupling and the worm gear reduces speed to make the main shaft and eccentric wheel rotate. The eccentric wheel drives the tappet to reciprocate in the guide cylinder. Together with the diaphragm, the one-way valve gradually forms a vacuum in the pump chamber, the suction valve opens, and the liquid is sucked in; when the diaphragm moves to the forward dead point, the suction valve closes, the discharge valve opens, and the liquid is discharged under the push of the diaphragm. The pump works by adjusting a certain stroke to reciprocate and form a continuous pressure and quantitative discharge of liquid.
The mechanical diaphragm metering pump is mainly composed of three parts: motor, transmission box, and cylinder. Smooth pulsation design, small impact. Variable eccentric sliding shaft adjustment mechanism, crank connecting rod drive. Strong and durable, low maintenance cost, mechanically driven PTFE diaphragm (various diaphragm materials), various materials and pump structures are optional, stable accuracy ±2% (adjustment ratio 10%-1)
1.Wear-resistant ball bearings make the work more stable, and the enhanced structural design is suitable for harsh operating environments.
2.Mechanically driven PTFE diaphragm (various diaphragm materials), no diaphragm protection plate on the material side, which is convenient for the material to pass.
3. Variable eccentric mechanism adjustment ensures smooth flow pulsation and stable performance.
4.Flow can be adjusted in shutdown or running state.
5.Small installation space.
6.Oil bath lubrication, long service life of drive components.
7.PVC, PVDF, 316SS, high viscosity and other pump head materials are suitable for conveying various materials.
8.Self-cleaning one-way valve structure for easy maintenance.
This pump can be widely used in industrial and scientific departments such as petroleum, chemical, textile, food, papermaking, atomic energy technology, power plants, plastics, pharmaceuticals, water plants, environmental protection, etc. It is used to accurately and quantitatively deliver liquids without solid particles to pressurized or normal pressure containers and pipelines.
This type of pump can deliver corrosive or non-corrosive liquid media with a temperature of -30℃-80℃ and a viscosity of 0.3-1000mm2/s without solid particles.
