The electric pump uses O-type rubber sealing ring as static seal, compact structure, good sealing performance, and adopts rubber vulcanization curve control technology, to ensure the O-type ring oil resistance, moisture resistance and aging quality and sealing performance. The dynamic seal adopts two sets of mechanical seals, and the oil chamber isolation protection, which effectively provides lubrication for the rotating friction pair, forms fluid film lubrication protection, and releases the heat accumulated during operation, thus extending the service life of the mechanical seal and ensuring the sealing performance.

The fluid parts of the electric pump are made of wear-resistant alloy cast iron, and the water pump part is made of fluid mechanical design and dynamic balancing technology, which effectively extends the service life of the electric pump. The pump part adopts the section type multistage pump structure which is easy to disassemble. This structure balances the radial force of the pump shaft and reduces hydraulic impact. It has a balanced axial force structure such as auxiliary mouth ring and pressure relief hole, which greatly prolongs the service life of the bearing. In addition, the electric pumps are designed to implement shutdown flushing to avoid clogging the impeller structure.
