6.2 Design of product
• Helix pumps are vertical high pressure non-self
priming pumps with inline connection based on
multistage design.
• Helix pumps combine use of both high efficiency
hydraulics and motors (if any).
• All metallic parts in contact with water are made
of stainless steel.
• For aggressive fluid, special versions exist with
stainless steel only for all wetted components.
• A cartridge seal is used as standard for all Helix
range in order to ease maintenance.
• In addition, for heaviest motor > 90lbs (40Kg), a
specific coupling allows to change this seal with-
out removing the motor.
• Helix lantern design integrates an additional ball
bearing that withstand hydraulic axial forces: this
allows the pump to use a fully standard motor.
• Special handling devices are integrated in order to
facilitate pump installation.
