Our Company
RUDI Pump (Shanghai Rudi Fluid Conveyor Co., Ltd.) is a professional manufacturer of air-operated diaphragm pumps, with over 20 years of experience in this industry. The company has two production bases, three branch offices, and approximately 120 employees, including more than 30 engineers.
Our pumps have obtained over 30 patents, as well as CE, ISO9001, and SGS certifications. Due to our consistent quality, we have received great recognition from our customers over the years.
The air-operated diaphragm pumps produced by RUDI use compressed air as a power source and are currently among the most advanced types of diaphragm pumps on the market. They utilize a three-way air pilot valve to achieve real no-dead-stop operation and faster reversing. Compared to traditional domestic pumps, they offer higher flow rates, more stable operation, and less pulsation. These pumps are widely used in wastewater treatment, chemical, petrochemical, painting, ceramics, environmental protection, printing, and dyeing industries to handle various corrosive, volatile, flammable, and toxic fluids with particles and high viscosity.
We offer a range of materials, and our engineers will help you choose the most suitable and cost-effective option based on your specific working conditions.
Wetted parts material: PP, PVDF, Acetal, Aluminum Alloy, Ductile Iron, Stainless Steel, etc.
Diaphragm material: Teflon, Santoprene, Viton, Hytrel, Buna-N, etc.
