Scope and installation
Pumps of this series are recommended for chemically nonaggressive liquids. The constructive solution of the driving wheel of open type allows to pump over the polluted liquids without danger of obstruction of the driving wheel. Thanks to this design feature pumps of the NGA series find the application in the industry, water supply from canals, the rivers, capacities, pools, etc. Installation has to be made in the rooms or places protected from atmospheric action.
Pump housing: cast iron, branch pipes with ISO 228/1 carving.
Pump housing cover: AISI 304 stainless steel.
Driving wheel of open type: AISI 316 stainless steel.
Leading shaft: EN 10088 - 3 stainless steel - 1.4104.
Mechanical consolidation: ceramics - graphite - NBR.
Electric motor: pumps are connected to the PEDROLLO electric motor of the corresponding power. The engine is silent, the closed type with external ventilation, it is calculated on work in the constant mode. NGAm: single - phase 230 V - 50 Hz with the condenser and the thermal protection which is built in a winding. NGA: three - phase 230/400 B - 50 Hz.
Isolation: class F.
Degree of protection: IP 44
