Self-Priming Technology of Yida YD Acid-Alkali Pump Solves Low Liquid Level Transmission Difficulties for Global Chemical and Sewage Treatment Facilities

Traditional anti-corrosion centrifugal pumps rely on pre-filled liquid and external bottom valve accessories to complete liquid suction work, which increases project construction investment and potential leakage risks for overseas chemical projects equipped with underground liquid storage pools. The structural innovation of YD coaxial self-priming acid and alkali resistant pump effectively resolves this long-standing universal pain point in the industry.

The pump body adopts integrated thickened fiber reinforced polypropylene molding with strong tolerance to corrosive liquids such as waste acid, alkaline wastewater and oxidizing media, applicable to waste acid recovery, industrial wastewater treatment and electroplating tank liquid circulation. After initial liquid injection during startup, the built-in self-priming chamber can quickly form negative pressure to complete liquid extraction, maintaining stable operation under intermittent production and liquid level fluctuation conditions. The horizontal coaxial layout shortens the transmission distance between the motor and pump body, reduces internal energy loss and the overall height of the equipment, which is more suitable for compact workshop layout and containerized integrated sewage treatment equipment supporting installation. Equipped with fully enclosed industrial full-copper motors, the product has low operating noise and high operational efficiency, complying with EU unified energy-saving design directives for industrial power equipment.

For working scenarios with high requirements for medium sealing and volatile substance isolation, customers can select CQF-Z self-priming magnetic pumps as alternative solutions. The two self-priming product lines undertake different application scenarios respectively, covering most self-suction demands in the global corrosive fluid industry. The global anti-corrosion pump market maintains steady growth, among which self-priming pump products obtain the fastest growth rate driven by the renovation and expansion projects of small and medium chemical factories in multiple emerging markets. Relying on stable self-priming performance and lower total ownership cost compared with European and Japanese competing products, YD series has gained repeated bulk procurement intentions from chemical engineering contractors in Southeast Asia and the Middle East market.
