End-suction long-coupled single-stage pump
NK 32-205.1/207 AA1F1S3ESBQQEMW1
Number: 93330740

Applications:

Commercial heating

Compliance: Standard pump in accordance with EN 733

NK 32-205.1/207 AA1F1S3ESBQQEMW1
The non-self-priming single-stage volute centrifugal pump is designed in accordance with ISO 5199, and its dimensions and rated performance comply with EN 733. The flanges are of PN 10 type, with dimensions conforming to EN 1092-2. The pump is equipped with an axial suction port, a radial discharge port, and a horizontal shaft. It adopts a back-pull-out design, allowing maintenance personnel to disassemble the coupling, bearing bracket, and impeller without loosening the motor, pump casing, and pipelines. The unbalanced O-type shaft seal meets the requirements of DIN EN 12756. An air-cooled base-mounted asynchronous motor is installed on the pump, with both the pump body and the motor mounted on the same base frame.
