Hydraulic diaphragm metering pump equipment sucks in immediately according to the repeated movement of plunger and discharged material (light yellow). When the plunger touches the sealing material, select appropriate materials and plunger sealing methods to ensure satisfactory operating characteristics. Hydraulic diaphragm metering pump is divided into valve pump and hydraulic mechanical pump. Diaphragm metering pump has the advantages of simple structure, high temperature and high working pressure. It is widely used in the field of petrochemical equipment.

Under the low viscosity working pressure of general piston pump, the accurate measurement of valveless rotary piston pump is more and more widely used in sugar paddle, chocolate and low viscosity grease additives. Because of the lack of protection between the tested substance and the gasoline pump, there are many restrictions when the hydraulic diaphragm metering pump is used to accurately measure the high resistance liquid, which will cause environmental pollution.

Hydraulic diaphragm metering pump is used to accurately transport liquid with solid particles in quantity, and is used for high-pressure vessels or class II pressure vessels. Different types of plunger dosing pumps can be used to install motor (4 ~ 20mA current data signal can be accepted) or explosion-proof motor piston rod head structure. The pump is simple, economic development, accurate, and needs selection and maintenance. Automatic and accurate maintenance between plunger and seal level.

Characteristics of hydraulic diaphragm metering pump equipment:

1. High pressure, suitable for high pressure water pump.

2. It is not recommended to transport corrosive mortar and hazardous chemicals when transporting low viscosity substances.

3. The water pump seal is a seal and a leakage seal. Be sure to adjust the filling material of preload on time. Filler and plunger are a pair of sensitive parts.

4. Simple structure, convenient maintenance and high cost performance.

5. The total flow is controlled according to the length of the travel arrangement, and the frequency conversion motor and frequency conversion governor are used to operate the total flow of the motor to complete the remote operation.

6. It can be used for various types of heat preservation pumps, long series, different liquid medicine, different data flow and working pressure.
