what is double diaphragm pump?
The Double Diaphragm Pump is a high-performance pump that uses the alternating reciprocating motion of two flexible diaphragms to transport fluids. It integrates safety, durability, and precise control, and can be widely used in various liquid transport and dosing systems in industries such as chemical, electronics, electroplating, water treatment, pharmaceuticals, printing and dyeing, and new energy.
Developed independently by Asenhe, the Double Diaphragm Pump is designed with high precision, long lifespan, and corrosion resistance as its core design principles. The pump body is made of high-polymer corrosion-resistant materials, and the internal flow channels have been precisely optimized to easily handle acids, alkalis, solvents, sewage, and high-viscosity media. The diaphragm section uses high-strength composite materials, possessing excellent wear resistance and fatigue resistance, maintaining stable performance under high-frequency operating conditions, and significantly extending its service life.
Structurally, the Double Diaphragm Pump utilizes a symmetrical drive and balanced chamber design, which results in more stable flow output, less pulsation, and lower noise, while also featuring strong self-priming capability and the ability to run dry. The advanced valve structure avoids the downtime risks associated with traditional pumps due to air resistance and valve jamming, ensuring reliable operation even in harsh environments.
Leveraging Assen River's extensive experience in fluid control, we not only offer high-performance double diaphragm pumps but also provide customized dosing and delivery solutions. This enables our Double Diaphragm Pumps to deliver precise, efficient, and stable performance in industrial wastewater treatment, electrolyte delivery, and high-purity media transport, providing customers with safer and more economical fluid management.
Whether you are in the water treatment industry, electronics, electroplating, semiconductors, paper making, printing and dyeing, chemical industry, or even sludge dosing and treatment on plate and frame filter presses, our pumps can be used, as shown in the picture:
