Pumps are designed for pumping and delivery of all common sorts of paper stocks, service water, impure liquids and sludge suspensions particularly in the paper industry.

 

• these NRA pumps consist of their hydraulic and mechanic parts, coupled to each other in one unit,

• they are designed for pumping and delivery of all common sorts of paper stocks with consistency up to 6 %,

• their operating performance (delivery head, delivery quantities) can be adapted to on-site technologi-cal requirements through changes of the electric motor speed (1 475 or 780 rpm) and of the impeller diameter,

• the pH value of the fluid to be pumped can range from 4,5 to 7,6,

• viscosity of the pumped fluid has essential influence on operating performance of the given pump; increased viscosity brings its reduced delivery head and steeper QH curve, i.e. reduced delivered volumes and considerably higher power input of the pump motor

 

We manufacture impellers for NRA stock pumps.
