TP 350-780/4 A3-F-O-DQQE-YW3
Close-coupled single-stage volute pump with coaxial suction and discharge ports of the same diameter. The pump features a top-pull design. For example, the power head (motor, pump head, and impeller) can be disassembled for maintenance while the pump casing remains connected to the pipeline. It is equipped with a balanced O-ring seal, and the shaft seal complies with the DIN EN 12756 standard. Pipe connections are made via PN 25 DIN flanges (in accordance with EN 1092-2 and ISO 7005-2 standards). An asynchronous motor with a cooling fan is installed on the pump.
