TP 200-400/4 A-F-A-BQQE-UW3

Single-stage, close-coupled, volute (centrifugal) pump unit with in-line suction and discharge ports of identical diameter. The pump is of the top-pull-out design, i.e. the power head (motor, pump head and impeller) can be removed for maintenance or service while the pump housing remains in the pipework. The pump is equipped with an unbalanced rubber bellows seal. The shaft seal is according to EN 12756. All pipework connection is via PN 16 DIN flanges (EN 1092-2 and ISO 7005-2). The pump is equipped with a fan-cooled asynchronous motor.

Suitable for: Commercial air conditioning

NB 125-400/368 AASF2AESBQQETW3

Non-self-priming, single-stage, centrifugal volute pump unit designed according to ISO 5199 with dimensions and rated performance according to EN 733 (10 bar). Flanges are PN 16 with dimensions according to EN 1092-2. The pump has an axial suction port, radial discharge port, horizontal shaft and a back pull-out design enabling removal of the motor, motor stool, cover and impeller without disturbing the pump housing or pipework. The unbalanced rubber bellows seal is according to DIN EN 12756. The pump is close-coupled to a fan-cooled asynchronous motor.

Suitable for: Commercial air conditioning, Industrial heating, Irrigation

NBE 125-250/236 AASF2AESBQQEOWA

Non-self-priming, single-stage, centrifugal volute pump unit designed according to ISO 5199 with dimensions and rated performance according to EN 733 (10 bar). Flanges are PN 16 with dimensions according to EN 1092-2. The pump has an axial suction port, radial discharge port, horizontal shaft and a back pull-out design enabling removal of the motor, motor stool, cover and impeller without disturbing the pump housing or pipework. The unbalanced rubber bellows seal is according to DIN EN 12756. The pump is close-coupled to a fan-cooled, permanent-magnet synchronous motor. The motor includes a frequency converter and PI controller in the motor terminal box. This enables continuously variable control of the motor speed, which again enables adaptation of the performance to a given requirement.
