6.2 Design of product
ƒ
The Helix pumps are vertical high pressure non self-priming pumps with in-line
connection based on multistage design.
ƒ
The Helix pumps combine use of both high efficiency hydraulics and motors.
ƒ
All metallic parts in contact with water are made of stainless steel.
ƒ
For models equipped with heaviest motor (>40 kgs), a specific coupling allows to
change the seal without removing the motor. A cartridge seal is then used in order
to ease maintenance.

Special handling devices are integrated in order to facilitate pump installation (Fig.
7).
