Electromagnetic diaphragm metering pump

2023-05-04 20:09 9745 views

‌The electromagnetic diaphragm metering pump is a metering pump driven by electromagnet and designed to deliver small flow and low pressure liquid. It is popular in the industry for its simple structure, easy control, low energy consumption, accurate metering, convenient adjustment and low price. Sunrise petro can provide high-quality electromagnetic diaphragm metering pump to meet the demand of small metering flow.


The electromagnetic diaphragm metering pump is a kind of metering pump. The metering metering pump is a special positive displacement metering pump that can measure the delivered fluid. It is generally composed of control part, drive part, drive part and overflow part. The main difference between the electromagnetic diaphragm metering pump and other metering pumps is the drive part.

The composition of electromagnetic metering pump can be simply divided into three parts: driving power supply, electromagnetic driving mechanism and hydraulic end. The electromagnetic driving device is the core of the electromagnetic metering pump. It generates variable electromagnetic attraction according to the change of input power signal, and maintains the linear reciprocating motion of the plunger of the driving mechanism.



Flow range: 1-20L/H

Maximum pressure: 0.1Mpa

Diaphragm material: PTFE (flow passage end face)

Pump head material: PVC, PVDF (PTFE), 304, 316

Motor: 110/220V, single-phase, 50/60HZ



The Electromagnetic diaphragm metering pump of Sunrise petro has the following advantages.

  1. Electromagnetic drive design, simple structure, stable performance.
  2. The flow can be adjusted by manually adjusting the stroke to change the flow and adjusting the stroke frequency.
  3. The pump head and flow passage parts made of corresponding materials shall be configured according to the corrosion performance requirements.
  4. It is easy to install and equipped with filter bottom valve, injection valve and inlet and outlet hoses.
  5. Modular design, optional 4-20mA current signal or pulse signal control.
  • Gear metering pump
    Gear metering pump is a kind of gear pump. Only specific gear pump can be called gear metering pump. At the same time, the gear metering pump is one kind of metering pump, so gear metering pump has metering characteristics. In order to meet the market dem
  • Bellows metering pump
    The Standard Bellows Metering Pumps operate on a positive displacement principle. The rotation of the motor shaft is transmitted into an up and down motion through a lever pivot crank mechanism. This motion provides a continuous compression and expansion
  • Pneumatic diaphragm metering pump
    Pneumatic diaphragm pump is a new type of conveying machinery, which is the most novel pump in China at present. Compressed air is used as the power source to pump out all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flamm
  • Hydraulic diaphragm metering pump
    ‌Hydraulic diaphragm metering pump, one kind of plunger diaphragm metering pump, is a metering pump designed by combining the characteristics of plunger metering pump and diaphragm metering pump. The contact part between the metering pump and the metered
  • Mechanical diaphragm metering pump
    The mechanical diaphragm metering pump is a special positive displacement pump that can meet the needs of various strict technological processes. The flow can be adjusted steplessly within 0-100%, and is used to transport liquids (especially corrosive liq
  • Plunger metering pump
    ‌The plunger metering pump directly sucks and discharges the working medium through the reciprocating motion of the plunger. Since both the plunger and the seal are in contact with the medium, selecting the appropriate plunger material and seal form can e
