JONENG
The 304 stainless steel food-grade inline electric Wilden diaphragm pump is available in single-acting and double-acting types, with specifications covering a variety of flow rates and pressures. Made of 304 food-grade stainless steel, it features hygiene and safety, corrosion resistance, stable delivery, and easy cleaning and maintenance.
The 304 stainless steel food-grade inline electric Wilden diaphragm pump uses an electric drive mechanism to move the diaphragm in a reciprocating motion, thus achieving liquid transfer. The diaphragm movement causes a change in the pump chamber volume; when the diaphragm moves outward, the pump chamber volume increases, and liquid enters through the suction inlet; when the diaphragm moves inward, the liquid is forced out of the pump outlet. A check valve ensures that the liquid flows in only one direction, preventing backflow and leakage. The diaphragm completely isolates the medium from the drive components, ensuring food-grade safety and hygiene. This pump is suitable for the continuous and stable transfer of slurries, beverages, dairy products, and other food liquids.

Constructed from 304 food-grade stainless steel, ensuring corrosion resistance, hygiene compliance, and safe handling of consumable liquids.
Inline electric design provides continuous, stable fluid transfer with precise pressure control, minimizing flow fluctuations in processing systems.
Diaphragm-driven mechanism isolates the fluid from moving parts, preventing contamination and maintaining sanitary conditions during operation.
Single or double-acting options allow flexible flow rates and capacities, adapting to diverse production requirements in food and beverage industries.
Easy-to-clean and maintain structure supports quick disassembly, CIP/SIP cleaning, and long-term reliable performance in hygienic applications.
Stainless Steel 0.55kW–22kW pneumatic diaphragm pumps are widely used in the chemical industry for conveying acidic and alkaline liquids and solvents, in the food and beverage industry for conveying slurries, syrups and juices, in the pharmaceutical industry for transferring liquid raw materials and intermediates, and in environmental protection and water treatment systems for conveying sewage or suspensions.
