The sealless self-control self-priming pump adopts a dynamic sealing device, so there is no worry about “running, popping, dripping or leaking”. On the basis of absorbing the advanced experience of related self-priming pump products at home and abroad, the improved and innovative products are replacements for traditional domestic similar products. This product has the advantages of temperature resistance, pressure resistance, wear resistance, “first drainage, permanent self-priming”, etc. After the product was put on the market, it was welcomed and praised by the majority of users for its unique design and reliable quality, and was selected by many units to replace imported products.

Since there is no friction or wear of the sealing device during operation, the service life is several times longer than that of similar products.
The pump has multiple functions such as temperature resistance, pressure resistance, wear resistance, “one-time drainage, lifelong self-priming”, etc. The self-priming performance is reliable, especially the “electric air control valve” which has the characteristics of reliable operation, convenient disassembly and easy installation.
