The electromechanical diaphragm pump uses a mechanical linear drive powered by an electric motor. This drive moves the diaphragm back and forth in a smooth, linear motion, which enables precise and controlled pumping. During the suction stroke of the diaphragm, a vacuum is created which opens the inlet valve and draws the medium into the chamber. During the pressure stroke, the medium is pressurized, the inlet valve closes and the outlet valve opens, pumping the medium out of the chamber. The inlet and outlet valves control the flow of the medium and ensure an efficient pumping process. The fact that only the diaphragms, valve balls and valve seats are in contact with the pumped medium minimizes wear. The pumps are also safe to run dry.
Electromechanical Diaphragm Pump in Metal:
The metal version is particularly robust and durable, ideal for applications with high mechanical loads. It offers high resistance to abrasion and corrosion, making it suitable for demanding environments. It is also versatile and can pump a wide range of media, including abrasive and viscous liquids.
Electromechanical Diaphragm Pump in Plastic:
The plastic version is specially designed for handling aggressive media. High-quality plastics such as polypropylene (PP) ensure high chemical resistance. This version is ideal for applications in the chemical industry and other areas of process technology where aggressive chemicals need to be pumped.
Electromechanical Diaphragm Pumps (EM) are extremely energy-efficient as they do not require compressed air or hydraulic fluid and can reduce energy consumption by up to 80% compared to compressed air pumps. They are safe to run dry, which increases operational safety and minimizes wear. These pumps ensure gentle pumping, ideal for sensitive media. They are versatile, as they can pump abrasive, corrosive, viscous and granular media.
EM pumps are available in different materials such as metal and plastic, making them suitable for a wide range of applications. By dispensing with compressed air, the operating costs are considerably lower compared to pneumatic pumps. The metal versions in particular are characterized by their robustness and durability, which makes them ideal for demanding applications. Electromechanical diaphragm pumps also offer a stable delivery characteristic. The flow rate is therefore independent of the back pressure, which distinguishes them from other pump types.
- Waste water treatment: Used in municipal and industrial waste water treatment plants for conveying sludge with fibrous components.
