Head Increased by 33% and Flow by 10%

Higher Pressure per Stage

• The patent-pending 3-D design allows a higher pressure per

stage for the same high efficient level

Hygienic Care

• No dead spaces in which the fluid might be able to stagnate

• Smooth material surfaces and corrosion-resistant stainless

steel prevent adhesion


HYDRAULICS – Best combination design & technology

High Efficiency via 3D impeller/diffuser Design

Helix 3D designs require very accurate

stamping and laser welding technology

reduced

by 70%


X-Seal - Wilo Cartridge for each pump

In case of maintenance on the Helix pump we offer2 alternatives:

2) Changing only the Mechanical seal(Grundfos can’t do it)

1) Changing the complete cartridge(like Grundfos)
