TP 125-745/2 A-F-R-BQQE-VW1
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 an unbalanced rubber bellows seal, and the shaft seal complies with the DIN EN 12756 standard. Pipe connections are achieved through PN 16 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.
