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

10
HYDRAULICS Best combination design technology

• High Efficiency via 3D impeller/diffuser Design
• Helix 3D designs require very accurate stamping
  and laser welding technology
• Laser welding technology
• competition use spot welding

Easy maintenance Cartridge Spacer Coupling
Maintenance time reduced by 70

• Spacer coupling from 7 ½ Hp
• No motor removal required

• Cartridge pre set
• No additional tools necessary

14
X-Seal - Wilo Cartridge for each pump
In case of maintenance on the Helix pump we
offer 2 alternatives
1) Changing the complete cartridge (like Grundfos)
2) Changing only the Mechanical seal (Grundfos
cant do it)
