DYI SHENG (TDS-DYISHENG) was founded in 1986 and has specialized in the R&D, design, and manufacturing of Air-Operated Double Diaphragm (AODD) Pumps since 1988. With nearly 40 years of global sales experience, we hold CE, ATEX, and ISO9001 certifications and are recognized worldwide for quality, innovation, and reliability. All pumps are 100% made in Taiwan with strict process control and 100% testing before shipment, ensuring long-term trust from international buyers.

Superior Reliability & Safety
Our patented air valve design enables pumps to operate with ultra-low air pressure (as low as 1.0 bar) and achieve 100% anti-stall performance. Built with explosion-proof safety, they deliver long service life with minimal downtime.

Wide Fluid Compatibility & Cost Efficiency
With multiple materials (Aluminum, Stainless Steel 316, Polypropylene) and diaphragm options (Teflon-PTFE/TFM, UPE, Santoprene), our pumps handle corrosive, viscous, and particle-laden fluids with ease. Buyers benefit from lower maintenance costs and versatile applications across industries.

Which industries are AODD pumps suitable for?
A: Our pumps are widely used in wastewater treatment, mining, chemical, coatings, oil & gas, food, pharmaceutical, and electronic industries, thanks to their ability to transfer almost all types of fluids safely and efficiently.

What certifications ensure pump safety and quality?
A: All our pumps are certified with CE, ATEX (explosion-proof), and ISO9001. Additionally, every unit is tested before shipment, ensuring consistent performance and compliance with international standards.

How do I choose the right pump model?
A: We provide pumps in 7 sizes (1/4” to 2”) and 3 material options. Selection depends on fluid type, chemical compatibility, and required flow rate. Our team offers professional guidance to recommend the best fit for your application.
