SE Network pumps for Pumping hot water
Type: Centrifugal pumps, horizontal, spiral type with double-entry impellers.
Purpose: used in heating networks for pumping water with a temperature of up to 180 0 C, containing solid particles no larger than 0.2 mm at a concentration of no more than 5 mg/liter.
Design: SE network pumps are centrifugal, horizontal, spiral with a horizontally split casing, single- and two-stage with transfer pipes with double-entry impellers. The rotor supports are external rolling bearings with crankcase lubrication. The shaft seals are mechanical with gland packing with a supply of cooling and locking liquid (-C), interchangeable with mechanical end seals (-T).
Materials:
bodies, covers – grey cast iron castings;
impeller – casting from chrome steel 20X13L;
gap seal parts - non-seize corrosion-resistant alloys;
shaft – rolled products made of structural alloy steel 40X.
Single-stage network pumps: SE 500-70-16, SE 800-55-11, SE 1250-70-11, SE 2500-180-10.
Two-stage network pumps: SE 800-100-11, SE 1250-140-11
