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

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

Hydraulic diaphragm metering pumps are used to accurately transport liquids with solid particles in quantities for high pressure vessels or secondary pressure vessels. Different types of plunger dosing pumps can be used to install motor (can accept 4~20ma electrical flow data signal) or explosion-proof motor piston rod head construction. The pump is simple, economical and accurate, requiring selection and maintenance. Fully automatic and accurate maintenance between plunger and seal level.

Hydraulic diaphragm metering pump equipment characteristics:

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

2, transport of low-viscosity substances, do not recommend the transport of corrosive sand and dangerous chemicals.

3, the pump seal is sealed and leak seal. Be sure to adjust the pre-load filler on time. The filler and the plunger are a pair of sensitive parts.

4, simple structure, convenient maintenance, high cost performance.

5, according to the adjustment of the length of the travel arrangement to control the total flow, the use of variable frequency motor and variable frequency governor to control the total flow of the motor, complete remote operation.

6, can be used for a variety of types of insulation pump, can be used for long series, can be used to add different liquid medicine and different data flow and working pressure.
