1, Product introduction
The mechanical diaphragm metering pump uses the motor to rotate the transmission gear，Reduce gear speed，The gears turn the eccentric turntable，The protruding part of the rotary eccentric turntable pushes the piston out，Then the diaphragm at the front of the piston pressurizes the liquid in the pump head cavity，And push the liquid medicine out;When you get to the bottom of the dial，The spring pushes the piston and diaphragm back，The vacuum state is formed in the pump head of the mechanical diaphragm metering pump，At the same time, the liquid medicine is sucked into the pump head cavity，The solution will be pushed out at the next push。
2Scope of application
Mechanical diaphragm metering pump is suitable for municipal, industrial water and wastewater, swimming pool and other water treatment projects。
3, product features
Measurement range: 0-1000L/H
Pressure range: 0-1.0MPA
Drive mode: motor drive
Control mode: manual adjustment
Cast aluminum shell, high heat dissipation, light weight, suitable for all kinds of acid and alkali liquids and corrosive liquids and hazardous chemicals;
Adopt CAM mechanism, no leakage on the whole, can be placed on the tank or pipeline, assembly and maintenance is simple and convenient;
The contact liquid part is PVC, PTFE and stainless steel are optional;
The flow rate can be adjusted by adjusting the stroke length and electrode frequency;
The diaphragm is made of multi-layer composite structure, the first layer of ultra-ductile TEFLON acid-resistant film, the second layer of EPDM elastic rubber, the third layer of supporting iron core, the fourth layer is reinforced by reinforced nylon fiber, and the fifth layer is completely wrapped by EPDM elastic rubber, which can effectively improve the service life of the diaphragm。
