NGA

Centrifugal pumps with open impeller

Description

Suitable for use with liquids that are not chemically aggressive towards the materials from which the pump is made.
The open impeller design allows liquids containing relatively high levels of impurities to be pumped without the risk of the impeller clogging. As a result of these characteristics the NGA series pumps are used specifically in industry and for transferring water from canals, rivers, reservoirs, tanks, etc.
The pump should be installed in an enclosed environment, or at least sheltered from inclement weather.
