Streisal - Model TSRM -Submersible Motors

The submersible motors in index of protection IP 68 are frequently used as drives for pumps, agitators, clearers and other units – for example for transporting sewage, polluted and waste water or sludges in municipal, industrial and private applications. Special applications such as lock drives, etc. are possible.

For use in potentially explosive areas, the motor series can be selected with the "pressure-tight encapsulation" explosion protection type II 2G Ex d ib IIB T3 according to ATEX. The maximum coolant/medium temperature is 60 °C.

The new series of highly efficient submersible motors is available with efficiency classes IE2 (high efficiency) and IE3 (premium efficiency). This reduces electricity consumption and saves energy costs.

The motor connection and the control connections are made by a shared, water-tight connecting cable which is configured to resist aggressive media.
Depending on the power rating and application, the motors can be operated with a direct connection, star-delta starting, soft starting or also with frequency inverters.

Robust, sturdy attachment options are provided on the rear of the housing and on the side at the cable outlet, meaning that the add-ons (such as pumps, gear units, etc.) generally do not need to be used for suspension. The attachment axis on the solid cable outlet provides the opportunity of a swivelling option directly for the housing.

The shaft seal for the inside of the motor is always a silicon carbide mechanical seal, which is thus resistant to pressurised water (IP 68). The standard equipment of our new series with ratings from 1.5 to 18.5 kW also includes temperature monitoring in the motor winding and a leakage probe for monitoring the leak tightness in the output end bearing plate.
