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 achieved over 30 patents, as well as CE, ISO9001, and SGS certifications. Thanks to our reliable quality, we have earned great appreciation from our clients over the years.
The air-operated diaphragm pumps produced by RUDI use compressed air as the power source and are among the most advanced in the market. They utilize a three-way air pilot valve for real no-dead-stop operation and faster reversing. Compared to other traditional domestic pumps, they offer a larger flow rate, more stable performance, and smaller pulsation. These pumps are widely used in wastewater treatment, chemical industry, petrochemical industry, painting, ceramics, environmental protection, printing and dyeing, etc., to handle various corrosive, volatile, flammable, and toxic fluids with particles and high viscosity.
We offer a variety of materials, and our engineers will select the most suitable and cost-effective option based on your specific working conditions.
Wetted parts materials: PP, PVDF, Acetal, Aluminum Alloy, Ductile Iron, Stainless Steel, etc.
Diaphragm materials: Teflon, Santoprene, Viton, Hytrel, Buna-N, etc.
Available inlet/outlet sizes: 1/4", 3/8", 1/2", 3/4", 1", 1-1/2", 2", 3"
Connection types:
- Threaded connection: Plastic pumps from 1/4" to 1-1/2", and all metal pumps.
- Flanged connection: Plastic pumps from 1/2" to 3".
