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.
ƒ
Special handling devices are integrated in order to facilitate pump installation (Fig.
7).
Installation and electrical work in compliance with any local codes and by qualified
personnel only.
WARNING
Bodily injury!
Existing regulations for the prevention of accidents must be observed.
