1.4.2 Impellers

Open and closed multi vane impellers for clean to slightly soiled pumped media and operationally safe pumping are used.

1.4.3 Installation

The pumps can be delivered in various installations:

Horizontal installation of the pump

General information

Caution!

Dry running the pump will destroy the mechanical seal!

Ensure there is adequate cooling and lubrication for the sliding surfaces.

Danger!

Air bubbles or accumulations of gas around the mechanical seal create a dangerous explosive atmosphere.

Provide a constant supply of pumped media to the feed and pressure pipe as well as the interior of the pump.

Provide appropriate monitoring measures to ensure this.

Vertical installation of the pump

It is not permitted to install the pump with the "motor facing downwards" for operational safety reasons.

1.4.4 Shaft sealing

The shaft sealing on the pump side is effected in all models via a wear-resistant, maintenance-free mechanical seal that is adapted to the respective operating conditions.

All motors are equipped with a special seal for splash-proofing on the pump side.

An existing ETS X4 permits monitoring of the mechanical seal to protect it from dry running.

1.4.5 Drive

A three-phase motor with squirrel-cage drives the pump. The motor is cooled by the dissipation of heat from the cooling fins to the ambient air.

The motor in UNIBAD-GFC pumps is also equipped with a jacket. The pumped medium cools this and absorbs the motor heat.

In the case of pumps of the type UNIBAD-GF-PM, a synchronous motor with permanent excitation for operating the frequency converter drives the pump. Observe the operating instructions included in delivery!

Important!

Observe the limit temperatures specified in section 1.4.7 'General data'.

Page 12

General information

The exact motor data can be found on the name plate.

Caution!

Incorrect warming will damage the three-phase motor.

Maintain the voltage tolerance of ± 10% according to DIN EN 60034-1.

5.1 Installation

Prepare the construction in accordance with the pump dimensions.

Important!

Provide sufficient room for maintenance and repair procedures!

Plan for sufficient room for opening the terminal box, for the electrical connection, and for any existing frequency converters.

The concrete foundation must

- have hardened,

- exhibit satisfactory rigidity (at least class X0 according to DIN EN 206),

- have a horizontal and flat surface and

- be able to absorb vibrations, effects of force and impacts, etc.

Only then should the pump be installed.

Caution!

Injuries may be caused when installing the pump.

Observe the safety regulations and the generally recognised "codes of practice".

Caution!

A hot pump casing and hot suction cover can burn hands and arms.

Do not touch pumps that deliver hot water. Take precautionary measures to prevent burning.

The connection flanges must be perfectly aligned and screwed in such a way that prevents leakage. The seals must be resistant to the pumped medium.

Caution!

Incorrect warming will damage the three-phase motor.

Ensure there is an adequate supply of cooling air during operation (except for type UNIBAD-GFC).

In order to prevent transferring vibrations to the building and the pipeline system it is recommended to install pipe compensators and vibration dampers.

5.4 Electrical connection

The electrical connection should only be established by an electrician.

Important!

In the case of PM motors, observe the operating instructions included in delivery!

Warning!

An incorrectly established electrical connection can result in death.

Connect according to DIN VDE 0100; also comply with DIN VDE 0165 in potentially explosive atmospheres.

The earth, neutral connection, fault current protection circuit, etc. must

- correspond to the directives of the local public utility company (PUC) and

- function flawlessly according to the electrician's inspection.

The cross-section and voltage drop of the feed line must comply with the respective regulations.

Installation / fitting

Warning!

Electric current can result in death.

Provide equipotential bonding between the pump casing and building earth.

5.5 Motor protection

Use a motor circuit breaker or adequate motor protection with a tripping characteristic according to DIN VDE 0660.

Accommodate the integrated temperature monitors (e.g. PTC thermistor) in the motor control circuits in such a way that if the temperature monitor responds it results in switching off the motor.

Important!

The motor protection switch should be

- regulated for nominal motor current during direct starting,

- introduced into the delta link for star-delta starting and set to maximum 0.58-times the nominal current.

The standard versions of the motors from 5.5 kW at 1500/1800 min-1 and motors of the UNIBLOCK-GFC and UNIBLOCK-GF-PM type pumps ex works have a PTC thermistor (see Section 5.7.1, PTC Thermistor Connection).

Caution!

Incorrect warming will damage the three-phase motor.

Maintain the voltage tolerance of ± 10% according to DIN EN 60034-1.

Warning!

If the winding protection is triggered, it can result in a potentially fatal explosive atmosphere.

Do not reactivate the system without previously checking it and eliminating the cause of the disturbance.

Page 38

Installation / fitting

5.6 Direction of rotation check

Make sure you check the direction of rotation during the initial commissioning procedure and also at each new installation location of three-phase pumps. An incorrect direction of rotation results in decreased pump power output and can damage the pump.

Caution!

Dry running the pump will destroy the mechanical seal!

After starting up the pump switch it off again immediately.

Danger!

The rotating impeller can cut or crush hands and arms.

Safeguard the pump when checking the direction of rotation.

Do not reach into the pressure flanges or the intake port of the pump casing.

Danger!

Risk of potentially fatal explosion during the installation phase.

Provide a constant supply of pumped media to the feed and pressure pipe as well as the interior of the pump.

Provide appropriate monitoring measures to ensure this.

Only then should you check the direction of rotation.

It is possible to activate the pump temporarily (no explosion protection) for max. 3 seconds without the risk of dry running.

Each pump is to be inspected individually in the case of a control system with multiple pumps.

The direction of rotation corresponds to the rotation indicator arrow!

Important!

This must rotate clockwise when looking at the motor fan.

In pumps of the UNIBAD-GFC series, the motor shaft has to rotate clockwise from the direction of the motor cover.

Openings in the intermediate casing allow a glimpse of the motor shaft.

5.6.1 Change of direction of rotation

The direction of rotation can be changed by swapping two phases of the motor cable.

Pumps of the UNIBAD-GF-PM type only for operating frequency converters.

Up to 30/36 kW, frequency converters can also be connected in a direct mounting configuration (UNIBAD-GFC models are only wall-mounted).

Possible frequency regulation of the pumps in a range of 30 to 50 Hz (30 to 60 Hz) is dependent on the operating conditions.

Frequency regulation of pumps of the UNIBLOCK-GF-PM type depending on the operating conditions

Important!

Frequency converters must comply with the EU's low voltage and EMC directives.

Ensure measures are in place for complete ventilation during the laying procedure.

Pressure pipes

lay in a frost-free configuration,

secure and

connect so they are stress-free.

Pipe forces and moments should not affect the pump.

Install a ...

- gate valve immediately in front of the pump to close off the pipes. This enables the pump to be removed when the pipes are full.

- non-return valve between the pressure flange and gate valve. This prevents the pumped medium from flowing back after shutting off the pump and also it avoids liquid slugging.

5.11 Frost protection

Use AC / DC sensitive residual current circuit breakers if necessary.

5.9 ETS X4

For the mounting and electrical connection of the ETS X4, see the included operating instructions.

5.10 Laying the pipes

Lay the pressure pipes in accordance with the applicable regulations and the relevant accident prevention regulations.

Warning!

Escaping hot pumped media is potentially fatal.

Do not exceed the pipe forces.

Notice!

The effects of frost can damage the filled pump.

Empty pumps during prolonged periods of inactivity.

Caution!

Escaping pumped media can burn hands and arms.

Ensure the pump casing is free from pressure.

Only then should you empty the pump.
