Function of the product

• Helix pumps are vertical multistage high-pressure
non-self-priming pumps for in-line connection.
• Helix pumps combine highly efficient hydraulic
systems and motors.
• All metal components in contact with the fluid are
made of stainless steel.
• For models equipped with the heaviest motor
(> 40 kg), a specific coupling allows the seal to be
replaced without removing the motor. A cartridge
seal is then used in order to facilitate maintenance.
• Special handling devices are integrated to facili-
tate pump
30
installation.

Installation and electrical connection

All installation and electrical work may only be
carried out by qualified personnel and in compli-
ance with local codes and regulations!
WARNING! Risk of severe injury!
Ensure that all existing regulations concerning the
prevention of accidents are observed.
WARNING! Risk of electrical shock!
Ensure that any electrical hazard is avoided.
7.1 Commissioning
Unpack the pump and dispose of the packaging
in accordance with all regulations concerning the
protection of the environment.
7.2 Installation
The pump must only be installed in a dry,
well-ventilated and frost-free location.
CAUTION! Risk of damage to the pump!
Contamination and solder residue in to the pump
body may affect pump operation.
• It is recommended to perform any welding and
soldering work before installing the pump.
• Flush the system thoroughly before installing
the pump.
- Install the pump in an easily accessible position to
facilitate inspection or replacement.
- For heavy pumps, install a lifting hook (Fig. 2, Pos.
10) above the pump to facilitate its disassembly.
WARNING! Hot surface! Risk of burns!
Position the pump in such a way that any con-
tact with hot pump surfaces is prevented during
operation.
- Install the pump in a dry and frost-free place on
a flat concrete block using appropriate accesso-
ries. If possible, use an insulating material under
the concrete block (cork or reinforced rubber) to
avoid any noise and vibration transmission into
the installation.
WARNING! Risk of tipping!
Ensure that the pump is correctly secured to the
ground.
- The pump must be installed in an easily accessible
location to facilitate inspection and removal work.
The pump must always be installed perfectly
upright on a sufficiently heavy concrete base.
CAUTION! Hazard caused by foreign parts
inside the pump!
Ensure that all blanking plugs are removed from
the pump housing before installation.
NOTE: All pumps are factory-tested for their
hydraulic properties and may therefore contain
small amount of residual water. For hygienic pur-
poses, it is recommended to rinse the pump before
any installing it in any potable water supply.
- For installation and connection dimensions see
section 5.2.
