6.2 Design of product
• HELIX pumps are vertical high pressure non-self prim-
ing pumps with inline connection based on multistage
design.
• HELIX pumps combine use of both high efficiency
hydraulics and motors.
• All metallic parts in contact with water are made of
stainless steel.
• For models equipped with heaviest motor (>88 lbs),
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 facili-
tate pump installation (Fig. 7).
7. Installation and electrical connection
Installation and electrical work in compliance with any
local codes and by qualified personnel only.
