6.2 Design of product

• HELIX pumps are vertical high pressure non-self
priming pumps with inline connection based on
multistage design.

• HELIX pumps combine use of both high efficien­cy hydraulics and motors (if any).

• All metallic parts in contact with water are made
of stainless steel or grey cast iron.

• For aggressive fluid, special versions exist with
stainless steel only for all wetted components.

• Helix pumps are equipped with a simple mecha­nical seal or with a cartridge seal to facilitate
maintenance.

• In addition, for heaviest motor, a specific cou­pling allows to change this seal without remo­ving the motor.

• HELIX lantern design integrates an additional ball
bearing that withstand hydraulic axial forces: this
allows the pump to use a fully standard motor.

• Special handling devices are integrated in order
to facilitate pump installation (Fig. 8).

- Place the pump where it will be easy to reach, to
facilitate inspection and removal work. The pump
must always be installed perfectly upright on a
sufficiently heavy concrete base.

CAUTION! Risk of parts inside the pump!

Take care to remove closure members of the
pump housing before installation.

NOTE: Each pumps could be tested regarding
hydraulic features in factory, some water may
remain in them. It is recommended for hygienic
purposes, to carry out a rinsing of the pump
before any using with potable water supply.

- The installation and connection dimensions are
given § 5.2.

- Lift the pump carefully by using the integrated
hooks rings, if necessary with a hoist and suitable
slings according to the current hoist guidelines.

WARNING! Risk of fall!

Take care to pump fixations especially for the
highest pumps whose centre of gravity may lead
to risk during pump handling.

WARNING! Risk of fall!

Use integrated rings only if they are not damaged
(no corrosion ...). Replace them if needed.

WARNING! Risk of fall!

The pump must be never carried by using motor
hooks: these are only designed to lift the motor
alone.

7.3 Pipe connection

- Connect the pump to the pipes by using approp­riate counterflanges, bolts, nuts and gaskets.

CAUTION!

Tightening of bolts must not exceed 80 Nm
Use of impact wrench is prohibited.

- The circulation sense of the fluid is indicated on
the identification label of the pump.

- Pump must be installed in such a way that it is
not stressed by the pipework. The pipes must be
attached so that the pump does not bear their
weight.

- It is recommended that isolation valves be ins­talled on the suction and discharge side of the
pump.

- Use of expansion joints may mitigate noise and
vibration of the pump.

- As regards the nominal cross-section of the suc­tion pipe, we recommend a cross-section at least
as large as that of the pump connection.

- A check valve could be placed on the discharge
pipe in order to protect the pump against ham­mer shock.

- For direct connection to a public drinking water
system, the suction pipe must also have a check
valve and a guard valve.

- For indirect connection via a tank, the suction
pipe must have a strainer to keep any impurities
out of the pump and a check valve.

- In case of half flanges pump design, it is recom­mended to connect the hydraulic network and

then keep out the plastic fixation links to pre­vent any leakage risk.

7.4 Motor connection for bare-shaft pump
(without motor)

- Remove coupling guards.

NOTE: Helix pumps are equipped with captive
screws as required in the Machinery Directive.

- Install the motor on the pump by using screws
(FT lantern size – see product designation) or
bolts, nuts and handling devices (FF lantern
size – see product designation) provided with
the pump : check motor power and dimension in
WILO catalogue.

NOTE: Depending on fluid characteristics,
motor power could be modified. Contact WILO
Customer Services if needed.

- Close the coupling guards by screwing all screws
provided with the pump.

7.5 Electrical connection
WARNING! Electrical shock hazard!

Dangers caused by electrical energy must be
excluded.

• Electrical work by a qualified electrician only!

• All electrical connections must be performed

after the electrical supply has been switched off
and secured against unauthorized switching.

• For safe installation and operation a proper
grounding of the pump to the power supply’s
grounding terminals is required.

- Check that operating current, voltage and fre­quency used comply with motor plating data.

- The pump must be connected to the power sup­ply by a solid cable equipped with a grounded
plug-connection or a main power switch.

- Three-Phase motors must be connected to an
approved motor starter. The set nominal current
must correspond to the electrical data on the
pump motor name plate

- The supply cable must be laid so that it never touches
the pipework and/or the pump and motor casing.

- The pump/installation should be grounded in
compliance with local regulations. A ground fault
interrupter can be used as extra protection.

- The connection to the network must be in
accordance with the connection plan (Fig. 5).

7.6 Operation with frequency converter

- Motors used can be connected to a frequency
converter in order to adapt pump performance to
duty point.

- The converter must not generate voltage peaks
at motor terminals higher than 850V and dU/dt
slope higher than 2500 V/µs.

- In case of higher value, an appropriate filter must
be used : contact converter manufacturer for this
filter definition and selection.

- Strictly follow instructions provided by the
converter manufacturer data sheet for installation.

- Minimum variable speed should not be set below
40% of pump nominal speed.

First, allow pump to cool down.

- These pumps are maintenance free. Nevertheless
a regular check is recommended every 15 000
hours.

- Optionally, the mechanical seal for certain
models can be replaced easily thanks to its car­tridge design.

- In case of pump with half flanges design and ins­tallation again after maintenance operation, it is
suggested to add plastic link to maintain in easy
way the half flanges together.

- For pumps equipped with one grease feeder (Fig.
7, pos. 1), respect lubrication frequences menti­oned on sticker glued on lantern part (2).
