SAFETY

  • The TSRM motor series is available in the "pressure-tight encapsulation" ignition protection type (Ex db) according to ATEX and IECEx for use in potentially explosive atmospheres (zones 1 and 2).
  • PTC thermistor as overheating protection
  • Temperature monitoring in the motor winding
  • Monitoring of the sealing system by "streisal Toplimiter" leakage probe in the output end bearing plate

PRESSURISED WATER-TIGHT DRIVES

The submersible motors with IP 68 index of protection are frequently used as drives for pumps, agitators, scrapers and other units – for example, for pumping clear, dirty and waste water or slurries in municipal, industrial and private areas. Special applications such as lock drives, etc. are possible.

EXTREME OPERATING CONDITIONS

The motor series is available in the "pressure-tight encapsulation" ignition protection type (Ex db) according to ATEX and IECEx for use in potentially explosive atmospheres (zones 1 and 2).

The maximum medium temperature is 60 °C.

ENERGY EFFICIENCY

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.

ELECTRICAL CONFIGURATION AND CONTROL

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.

MOTOR SUSPENSION

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, gearboxes, 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.

RELIABILITY

The shaft seal to the inside of the motor is always provided by a silicon carbide mechanical seal, and is therefore pressurised water-tight (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.
