Circulator & Hot Water Pumps

Description Specification Downloads Description Characterised by the use of multi-impeller vertical axis electric pumps, these sets are acclaimed for their high efficiency, application versatility, and very low noise operation. Utilised in large scale civil and industrial installations, selection of these sets must be performed by skilled engineers capable of assessing the effective requirements of the systems on which they are to be installed. Construction features SETS WITH 2-3 PUMPS. Features HYDRAULIC SECTION 2-3 Multistage vertical electric pumps NKV 10 - NKV 15 NKV 20; Skid in galvanized steel; Flanged suction and discharge manifolds in galvanized steel complete with blank flange; Isolator valves on suction and discharge ports; Check valve for each pump; Radial pressure gauge with isolator valve; Galvanized steel column for mounting of the control panel; Membrane pressure tanks. ELECTRICAL SECTION The pump sets are supplied in a strong carton on a wooden pallet complete with instruction leaflet and wiring diagram.
