High-flow stainless steel electromagnetic control diaphragm pumps are available in single-acting and double-acting types, with specifications covering a variety of flow rates and pressures. They are commonly made of 304 or 316L stainless steel and feature high flow rate delivery, corrosion resistance, precise control, stable and efficient operation, and easy maintenance.
The high-flow stainless steel electromagnetically controlled diaphragm pump uses an electromagnetic valve to control the reciprocating motion of the diaphragm within the pump chamber, achieving liquid transfer. When the electromagnetic valve is energized, it pushes the diaphragm inward to pressurize the liquid, causing it to be discharged from the pump outlet. When de-energized, the diaphragm rebounds, increasing the pump chamber volume and drawing liquid in through the suction inlet. A check valve within the pump body ensures the medium flows in the designated direction, preventing backflow. The diaphragm completely isolates the liquid from the drive system, ensuring corrosion resistance, hygiene, and leak-proof performance. It is suitable for high-flow, high-precision liquid transfer in industries such as chemical, food, pharmaceutical, and water treatment.

● The stainless steel sanitary double diaphragm pump adopts a dual-chamber structure, which automatically adjusts the internal pressure during the conveying process, reduces pulse fluctuations, and ensures flow stability.
● The stainless steel sanitary double diaphragm pump optimizes the flow channel through computational fluid dynamics (CFD), so that the fluid flows in the pump chamber with minimum resistance, reduces shear force, and ensures the integrity of sensitive materials.
● The micro-gap design between the valve ball and the valve seat of the stainless steel sanitary double diaphragm pump enables the valve ball to automatically adjust the sealing angle during operation, improve sealing performance, and reduce leakage.
● The stainless steel sanitary double diaphragm pump adopts a PTFE and EPDM composite diaphragm, the outer layer is corrosion-resistant, and the inner layer has enhanced elasticity. It can withstand high-frequency reciprocating motion, extend the life of the diaphragm, reduce the replacement frequency, and improve the long-term stability of the pump.
● The stainless steel sanitary double diaphragm pump adds a noise reduction buffer device in the pneumatic drive cavity, so that the compressed air forms a dispersed airflow when entering the pump body, reducing the airflow impact noise.
● When the internal pressure of the stainless steel sanitary double diaphragm pump increases abnormally, the built-in elastic pressure relief element will automatically release the excess pressure to prevent the pipeline or pump body from being damaged by overpressure.
Stainless steel high-power welded electric pneumatic diaphragm pumps are widely used in the chemical industry for conveying corrosive liquids and chemical raw materials, and also in the food and pharmaceutical industries for conveying slurries, additives, and cleaning solutions. Furthermore, in the environmental protection, water treatment, and electroplating industries, they can be used for the stable transport of wastewater, solid-containing media, or high-viscosity fluids, adapting to complex working conditions.
