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 field. The company has two production bases, three branch offices, and approximately 120 employees, including more than 30 engineers. Our products have achieved over 30 patents, as well as CE, ISO9001, and SGS certifications. We are known for our reliable quality and have received consistent praise from our global clients.
The air-operated diaphragm pumps produced by RUDI use compressed air as the power source, making them one of the most advanced types on the market. They feature a three-way air pilot valve that ensures smooth operation and faster reversing. Compared to traditional domestic pumps, they offer a higher flow rate, more stable performance, and less pulsation. These pumps are widely used in industries such as wastewater treatment, chemical processing, petrochemicals, painting, ceramics, environmental protection, and printing to handle corrosive, volatile, flammable, and high-viscosity fluids with particles.
We offer a variety of materials for wetted parts and diaphragms, ensuring the best fit for your specific application. Our engineers will help you select the most suitable and cost-effective option based on your working conditions.
