Hygienic Sanitary PTFE Lined Electric Double Piston Diaphragm PUMP
Sanitary PTFE-lined electric dual-piston diaphragm pumps are available in single-pump and dual-pump types, with specifications covering various flow rates and pressures. They are made of stainless steel with a PTFE lining and feature corrosion resistance, high-precision delivery, hygiene and safety, high temperature resistance, and easy maintenance.
This sanitary PTFE-lined electric dual-piston diaphragm pump uses a motor to drive two pistons in alternating reciprocating motion, enabling continuous liquid delivery. When the pistons move outward, the pump chamber volume increases, allowing liquid to enter through the suction inlet; when the pistons move inward, the liquid is forced out through the pump outlet. An internal check valve ensures the medium flows in the designated direction, preventing backflow. The PTFE-lined diaphragm effectively isolates the liquid from the metal pump body, providing excellent corrosion resistance and high-temperature resistance while ensuring hygiene and safety. This pump is suitable for the precise delivery of corrosive, viscous, or high-value liquids in the chemical, pharmaceutical, and food industries.

Constructed with PTFE-lined chambers and stainless steel, providing excellent chemical resistance and high-temperature durability for aggressive liquids.
Dual piston design ensures continuous, smooth flow with minimal pulsation, suitable for precise metering and high-capacity pumping.
Electric-driven mechanism allows automated operation, reducing manual intervention and improving efficiency in production processes.
Hygienic design with smooth surfaces and PTFE lining ensures sanitary handling and prevents contamination of sensitive fluids.
Easy maintenance and quick disassembly enable efficient cleaning, inspection, and long-term reliable performance in industrial applications.
The SS316L stainless steel Aro diaphragm pump, a high-suction slurry pump for chemical applications, is widely used in the chemical industry for conveying acid and alkali solutions, corrosive slurries, and solvents; in the mining and slurry treatment industry for handling high-viscosity slurries; and in the environmental protection and water treatment fields for conveying sewage or liquids containing solid particles, ensuring safe and stable transport.
