While pump developing and manufacturing the original constructive solutions have been used. It makes possible to increase the quality, reliability and operating life of the pumps. In order to increase the coefficient of efficiency the pumps are manufactured with I and II rotors and а, б, в, г working wheel grooving.

Grooving material is available as:

  • «С» (carbonic steel 25Л) 
  • «Х» (chromic steel 20Х5МЛ, 20Х13)
  • «Н» (chromium-nickel steel 12Х18Н9ТЛ)

In order to transmit torsional moment from electric engine to pump spindle it can be used both toothed and digital as well as plate-type muffs.

The front spindle or stuffing compaction is set at the spindle exit out of pump body; pump gear is explosion-proof electro-engines.

Oil fuel pumps НПС type

oil-fuel-pumps-nps-type

Purpose

Oil fuel pumps НПС type can be assigned for transferring and piping oil, oil products, dry hydrocarbon gases and other liquids, which have similar physicochemical features and the same corrosive impact to the pump component material; temperature from minus 80°C to plus 400°C. The allowed level of nonabrasive solid particles in the pumped fluid is not more than 0,2% w/w; the allowed particle size is not more than 0,2 mm.

Oil fuel pumps НПС type can be used in technological installations petrochemical, petro- and the gasprocessing enterprises, delivery system of fuel (Termal Power Station), large boiler and inflate stations.

Construction

Pumps НПС type – oil fuel centrifugal interbasic section eight-step cell type with a flat horizontal case. Details of a running part of pumps – carbon steel. Pump impeller – one-way: are located on a shaft in two groups by four wheels between portable ball-bearing support. For unloading of a rotor from axial forces entrance apertures of driving impellers of both groups are turned into the opposite sides. Greasing of bearings – liquid, circulating.
