2 PRT and, sealless Main applications Machine tools Humidifiers Filtering installations Beverage cooling installations Air conditioning Lapping machines Optical industry Cleaning/degreasing facilities Grinding operations Fluids delivered Aqueous emulsions (with synthetic/mineral oil), also with chemical additives Oils Drinking water Salt water Distilled water Deionized water Bases and acids Photo developer fluids Please consult our endurance table for the large number of other fluids the pumps can deliver. 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). Design features sealless free-floating pump shaft, supported only by motor bearings open impellers - to -stage models installation and connecting dimensions to DIN EN 257 immersion depths of up to 350 mm Sectional view: PRT 7 (3-stage) Mechanical design Component Model PRT Model Motor housing aluminum aluminum Pump support PPU PPU Pump bottom PPU PPU (PRT 22, 27, 32: LCP) ( 22, 27, 32: LCP) Intermediate PPU PPU chamber (PRT 22, 27, 32: LCP) ( 22, 27, 32: LCP) Impeller PPU PPU Shaft ETG Stainless steel W.-No..422 (others on request) Antifriction Radial deep-groove ball Radial deep-groove ball bearings bearings with two side bearings with two seals plates (2 Z), with (2 RS), with permament permament lubrication lubrication Shaft packing FPM (Viton) (underneath lower ball bearing) Splash ring NBR (Perbunan) FPM (Viton) (underneath flange) Top splash ring FPM (Viton) FPM (Viton) (above pump chamber) V-Ring NBR (Perbunan); (between fan except for 5, and motor housing) unventilated. 2

3 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. Standard Options Degree of protection IP 54 IP 55 (DIN EN /4.88) Insulation class F.B Ambient temperature max. 40 C 50 C and higher (DIN EN 0034-/.95) Relative humidity max. 92% 95 % and higher (DIN 5005) Site altitude < 000 m on request (DIN EN 0034-/.95) above sea level Electrical parameters 230/400 V, 50 Hz on request 255/440 V, 0 Hz Mains operation three-phase single-phase AC Number of poles 2 poles 4 poles; multiple-speed Terminal box layout (DIN EN 257) layout layout 2, 3 or 4 material high-impact plastic light metal cable entry Mx.5 M25x.5 (DIN 40430/2.7) Protective surface synthetic-resin Special finish lacquer on request. color: RAL 9005 (deep-black, dull) Special protection Motor protection (thermistors in the winding/ptc); fan cowl with canopy. 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. Model with agitator blades for fluids with fast sedimentation characteristics. (Please note: higher power required) Order Example PRT 7 H K-220 Model Size H = 50 Hz 0 Hz (with impeller change) K = 50/0 Hz (without impeller change) Immersion depth t Please indicate electrical parameters, e.g. 230/400 V, 50 Hz. When ordering spare parts, always indicate the -place serial number (see motor rating plate). 3
