1 Volute Casing Centrifugal Pumps of Inline Design Series NI Application For pumping pure water, industrial water, sea water, condensates, oils, brines, lyes and hot water. The fluids to be pumped must not contain any abrassive particles nor chemically attack the pump materials. Main fields of application In cooling and heating systems, in circulating, water supply, water treatment, seawater desalination, dedusting and spray painting plants as well as in airconditioning, cooling, swimming pool and industrial engineering. Design and series construction Volute casing centrifugal pump, single entry, single or twostage, of inline design. Pump according to DIN EN 733. Stub and motor shaft are rigidly coupled together. bearing in the motor by means of greaselubricated groove ball bearings. The mating dimensions of the twostage s 2/25 200/01, 2/32 200/01, 2/40 250/01, 2/50 250/01, except for dimensions f and l depending upon the driving motors, correspond to the singlestage designs. Horizontal or vertical installation, motor arrangement downwards is not admissible. Performance data Delivery Q up to 380 m 3 /h Delivery head H up to 145 m Temperature of the fluid pumped t up to 140 C Inlet pressure p s Pump outlet pressure as a function of the shaft diameter and the with diameter 16, 24, 30 p d up to 16 bar with diameter 40 p d up to 10 bar Drive power P 0,25 up to 37 kw Nominal diameter, delivery flange DN d 25 up to 150 Branch position/flanges Suction and outlet branch opposite in one line. Flanges: up to DN 150 acc. to EN PN 16 up to DN 200 acc. to EN PN 10 Explosion protection The pump fulfils the requirements according to EC Explosion Protection Directive 94/9EG (ATEX 100a) for equipment and equipment group II, category 2 G. Categorisation into temperature classes according to EN depends on the temperature of the pumped medium. The max. permissible temperature of the pumped medium for the respective temperature classes are shown in the specific order data sheet. Note: In case of the operation of a category 2 pump, the unacceptable heating of the pump surfaces caused by a possible operational fault must be prevented by a control mechanism. In case of an operation with constant parameters (pressure, temperature, speed = const.), a pump performance controller can be supplied with the pump to detect any operational faults. Drive Surfacecooled threephase squirrelcage induction motors, with locatingtype bearing, IM V1 type of construction, enclosure IP55 according to IEC Standard, class F insulation, performances and main dimensions according to DIN , up to 2.2 kw 230/400V, from 3 kw 400/690 V. Attention: Motors provided by customers must also have a locatingtype bearing! Dismantling the driving unit When dismantling the driving unit, the volute casing may remain in the piping.
