DYISHENG now has CE(by SGS,2025), and ISO9001 quality certifications(by QA INTERNATIONAL,2023). We take high-quality, swift service, innovative technology, honesty, and trustworthiness as our guiding principles. High-quality diaphragm and air valve TDS DYISHENG - Air-Operated Double Diaphragm pump has the best abrasive resistance in air valve design. We also have a Non-stall patent of pumps in the world. This design can save 15~20% air consumption at the same flow rate compared with other Air-Operated Double Diaphragm pumps. Silencer The muffler effectively reduces the noise generated when the air-operated duplex diaphragm Pump is working. Professional Air-Operated Design TDS-DYISHENG’s Air operated double diaphragm pumps are 100% Taiwan-made products with the best air valve design in the world. In normal working conditions, it can ensure 100% no-stall quality. The Pneumatic drive only needs 1.0 bar minimum to operate, without sophisticated controls, and has the advantages of high efficiency, low maintenance cost, etc. All-Bolted construction The Air Operated Double Membrane Pump is all-bolted construction, with good sealing, it can handle fluid without leakage. The diaphragm design of the pump prevents leakage to the outside of the pump or to the internal parts of the pump, ensuring the safety of the environment and operators. Please use the component produced by DYISHENG to service. Or it will damage other parts or reduce the efficiency. Wide Applications Pumps can be widely used in the automation industry, sewage treatment, mining, electroplating, chemical industry, electronics, construction, and other industries. From the electronics, petrochemical, and even food industries, air-operated diaphragm pumps occupy a leading position in the field of application.
