Electromagnetic diaphragm metering pumps
Electromagnetic diaphragm metering pump is driven by an electromagnet, designed for the delivery of small flows of low-pressure pipeline liquids and a kind of simple structure, low energy consumption, accurate metering and easy to regulate and welcome in the industry. The design is simple and practical, the disadvantage is that the metering flow rate is small (generally below 90L/h), the pipeline pressure requirements are relatively low.

The hydraulic end of the pump forms the working chamber with the help of a plunger, and the volume of the working chamber is periodically changed by the reciprocating linear motion of the plunger.

Hydraulic diaphragm metering pumps
as a diaphragm pump in which the hydraulic end of the pump is composed of a working cavity with the help of a diaphragm and a diaphragm periodic elastic deformation that replaces the reciprocating motion of the piston (plunger). The pump that directly drives the diaphragm to deflect and deform periodically before and after the reciprocating motion is called a mechanical diaphragm pump.

Hydraulic diaphragm metering pumps
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.

Complete dosing unit (skid block)
The complete set of dosing device is a new concept of chemical water treatment dosing equipment, which has been widely used in the fields of electric power, chemical industry, municipal and other water treatment at home and abroad. It is to install all equipment and components such as metering pumps, dissolving boxes, control systems and pipeline valves on the same base platform to realize the overall combination of dissolving and dispensing liquid medicine and metering and dosing functional units, which has the characteristics of compact structure, small footprint and easy transportation and installation.

Metering pump selection and use of precautions
According to the GB/T7782-2008 "Metering Pump" standard, "the flow metering accuracy of the pump under rated conditions and the maximum relative stroke length shall not be less than 1% of the soil". The ideal travel range of the pump when conveying general media, the piston metering pump and the hydraulic diaphragm pump are 30%~100%; The mechanical diaphragm metering pump is 40%~100%. When the range required by the process is ≤ 10%, the AC inverter can be added to reduce the speed and expand the range of use. The flow curve on the certificate is measured by the factory according to the normal temperature clear water performance test when leaving the factory, and the user should retest according to the actual working conditions and recalibrate the relationship curve between the stroke and the flow rate, so as to accurately adjust the flow rate during operation.
