The non - self - priming single - stage volute centrifugal pump is designed in accordance with the ISO5199 standard, and its dimensions and rated performance comply with the ISO 2858 standard. The flanges are of the PN 16 type, and their dimensions conform to the EN 1092 - 1 standard. This water pump has an axial suction port, a radial discharge port, and a horizontal shaft. It adopts a back - pull - out design, enabling maintenance personnel to disassemble the coupling, bearing bracket, and impeller without loosening the motor, pump casing, and pipes. The unbalanced O - type shaft seal meets the DIN EN 12756 standard. An air - cooled, base - mounted permanent - magnet synchronous motor is installed on the water pump. The pump body and the motor are mounted on the same base frame. The motor's terminal box contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the water pump to be adjusted to the optimal operating state according to environmental conditions.
