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).

nection
