Temperature range: -30 C to +0 C. Models Model PRT: Standard coolant pump for machine tools and systems. Model : Special model for aggravated conditions in the machinery and systems sector for a large number of industrial fluids (see also Mechanical Design ). The delivery rates of models PRT and are the same. Both models can be supplied in two variants: a) for 50 or 0 Hz operation: PRT..H and..h; b) for 50 and 0 Hz operation: PRT..K and..k (without impeller change).

PRT and, sealless Electrical design The drive motors have a sophisticated fail-safe winding that is baked instead of impregnated. They meet VDE regulations as well as European motor standards (DIN EN 0034-/.95) and the requirements underlying the CE mark. Designs in conformity with non-european regulations, e.g. Canadian Standards Association (CSA), Underwriters Laboratories INC. (UL) or special requirements, e.g. the USA or Japan, are possible. Moreover, we also produce models for special operating conditions (e.g. exposure to humidity or dust). The regular models have motor windings designed for continuous operation and connection to a mains voltage of 230/400 V ±0%, 50 Hz in accordance with IEC 38/5.87. On request the motors can be customized to all common mains values.

Used with converter on request Installation and operation The unit is installed in a vertical position. The maximum permissible level of fluid is 20 mm beneath the mounting flange (cf. following drawings). Dry running is not permitted. The pump may, however, run dry (no fluid) for a brief period of time to check the direction of rotation prior to startup. Operation against closed valve is possible. Direction of rotation: to the left (counterclockwise) as viewed from above looking down on the ventilation side of the motor. Options immersion depth extension tube Model with extension tube if immersion depth deviates from standard. immersion depth 20 mm max. permissible level of fluid 50 mm minimum level of fluid when pump switched on 20 mm max. permissible level of fluid Tested Safety (GS) regulations specify a motor circuit breaker conforming to the following tripping characteristic.
