TP 400-760/4 A-F-A-DBUE-YW3 A tightly coupled single-stage vortex pump with coaxial suction and discharge ports of the same diameter. The water pump is designed to be pulled up. For example, the power head (motor, pump head, and impeller) can be disassembled for maintenance while maintaining the connection between the pump casing and the pipeline. A balanced O-ring seal is installed on the water pump. The shaft seal complies with DIN EN 12756 standard. The connection of the pipeline is achieved through PN 40 DIN flanges (EN 1092-2 and ISO 7005-2 standards). An asynchronous motor with a cooling fan is installed on the water pump.
