By­pass kit 25 bar
Bypass kit (with air pressure gauge 25 bar)
Chassis with damping pads for pumps up to 5.5 kW
• IF module PLR for connecting to PLR/interface
converter
• IF module LON for connection to LONWORKS
network. These modules plug directly into
the connection interfaces of the converter
(see Fig. below).
• Non-return valves (with tab or spring ring for
operation at constant pressure)
• Protection kit against dry­running
• Pressure sensor kit for control (accuracy: ≤ 1 %;
use between 30 % and 100 % of the measure-
ment range).
Use only accessories that are new.

6.2 Product characteristics
• Helix pumps are vertical non­self­priming
high-pressure multistage centrifugal pumps for
in-line connection.
• Helix pumps combine hydraulics and high­
performance motors.
• All metal components in contact with the water
are made of stainless steel.
• For models equipped with the heaviest motor
(> 40 kg), a specific coupling allows the seal
to be replaced without dismantling the motor.
A cartridge mechanical seal is then used in order
to facilitate maintenance and repair.
• Special handling devices are integrated to
facilitate pump installation (Fig. 8).
