6.2 Design of product
ƒ
Helix pumps are vertical high pressure non-self priming pumps with inline connec-
tion based on multistage design.
ƒ
Helix pumps combine use of both high efficiency hydraulics and motors (if any).
ƒ
All metallic parts in contact with water are made of stainless steel or grey cast iron.
ƒ
For aggressive fluid, special versions exist with stainless steel only for all wetted
components.
ƒ
Helix pumps are equipped with a simple mechanical seal or with a cartridge seal to
facilitate maintenance.
ƒ
In addition, for heaviest motor, a specific coupling allows to change this seal
without removing the motor.
ƒ
Depending on the model, the pump casing is equipped with additional connections
for connecting accessories (Fig. 10).
ƒ
Helix lantern design integrates an additional ball bearing that withstand hydraulic
axial forces: this allows the pump to use a fully standard motor.
ƒ
Special handling devices are integrated in order to facilitate pump installation (Fig.
8).
