Company Introduction
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 field. 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. Thanks to our reliable quality, we have received consistent positive feedback from our clients over the years.
The air-operated diaphragm pumps produced by RUDI use compressed air as their power source and represent the most advanced type of diaphragm pump currently available on the market. They feature a three-way air pilot valve that ensures real no dead stop and faster reversing. Compared to other traditional domestic pumps, these models offer a larger flow rate, more stable performance, and reduced pulsation. They are widely used in wastewater treatment, chemical industry, petrochemical industry, painting, ceramics, environmental protection, printing, and dyeing, among others, to handle various corrosive, volatile, flammable, and toxic fluids with particles and high viscosity.
We provide a range of materials for the wetted parts, and our engineers will select the most suitable and cost-effective option based on your specific working conditions. Available wetted part materials include PP, PVDF, Acetal, Aluminum Alloy, Ductile Iron, Stainless Steel, etc. Diaphragm materials include Teflon, Santoprene, Viton, Hytrel, Buna-N, etc. Inlet and outlet sizes can be customized, ranging from 1/4", 3/8", 1/2", 3/4", 1", 1-1/2", 2", up to 3". Connection types include threaded and fanged connections, depending on the pump material.
