Submersible pumps with canned motor

The EC directive, which is reflected in the Federal Immission Protection Law and the TA-Luft, results in the fact that seal-less pumps, particularly the canned motor pumps in this case, are increasingly being used as “Best Available Technology” (BAT) to prevent and reduce volatile emissions. Canned motor pumps have no shaft sealing and are therefore completely leakage-free. The compact design of the canned pump, with integral motor sharing a common shaft results in a pump considerably shorter than either conventionally sealed or magnetic drive units. The length of the shaft is independent of immersion depth. Installation and removal of the pump can be effected more economically due to the individual design of the cable conduit and discharge pipe.

Hermetic offers a wide variety of mounting arrangements and two distinct pump models, the TCN and TCAM. The pumps are available with flow rates of up to 1800 m3/h, delivery heights of up to 1000 m, and canned motor powers are available with up to 448 kW. For hazardous area applications, Hermetic’s canned motor pumps are certified according to the EC Type Examination Certificate under directive 94/9/EG Atex.
