DOP-SB02912-PY Series Horizantal Multistage Centrifugal Pumps

Short Description:

Multi stage pumps with radial suction and discharge ports, suitable for use in heating systems conforming to VDI 2035, hot and cold domestic water systems, cooling/condense water systems, water/gylcol mixtures.
Pump shaft is sealed by soft packing (mechanical seals as an option), pumps require very low maintenance and they posses good cavitation free operation. 
Stage, suction and discharge bodies are assembled together by bolts outside pump body.     
Produced in PN40 nominal pressure class, they may be used in ambient temperatures up to 40°C and fluid temperatures between -10°C and 110°C. (140°C as optional)    
Pump stage, suction and discharge bodies and impellers are manufactured from GG25, pump shaft from X20Cr13, shaft packing sleeves from stainless steel. 
Pump and motor shafts are coupled by a coupling. Coupling protection provides complete protection and conforms to equipment operational safety standart EN294 and DIN 31001 norm. Drive motor is a standart motor with insulation class of F and protection class of IP55.
