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

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)
