Pumps PSH has presented the only plastic injection impeller in one one piece and with helical blades existing in the world!
This new impeller has been awarded with the "Sustainability Award 2013"
This impeller is a world first, is the only impeller respecting the form of the original helical blades that provide optimum performance to the GIANT pump. Shape looks like the traditional casting impellers and provides the best possible performance.
The choice of a turbine with helical blades relative to a turbine with perpendicular blades to its plate, represents a performance improvement from 5% to 10%. As example for a 7.5 kW pump equivalent to having permanently open, 24/24, 365/365 days, 10 bulbs of 75W unnecessarily.
