Pump Data
Minimum required suction height in 40°C
ambient temperature at the suction side
of the pump to prevent cavitation noise.
(mWc)
HCPO-Al 6/13
When there is cavitation in a circulation pump, the following problems arise:
Low performance: Since the required flow conditions are not met, pump
cannot create the necessary flow rate and pressure. Upper floors cannot be
heated.
Vibration: Turbulent flow caused by air bubbles causes vibration.
Pump life is reduced: Air bubbles in the system or in the pump corrode the
pump material causes erosion.
Noise: Air bubbles, turbulence and striking of water on surfaces create noise.
HCPO 5/10
When the pressure at the suction end of
the circulation pump is not enough, water
changes phase to turn into gas. Gas bubbles
are carried to high pressure areas by the
flow. Vapour turns into water again and
gas bubbles causes turbulence in the flow
and water strikes the surfaces. This process
is called cavitation.

Do not operate the pump without water.
NEVER LUBRICATE THE PUMP
Rods and bearings of ALARKO circulation pumps are water lubricated and they do not need
maintenance. New or idle pump rods may be throttled due to the pollutants and particles in
the water. In such cases, close the main electric switch. Remove the rotor end cap and rotate
the shaft a few rounds via screwdriver. Put the rotor end cap in place and operate the pump.
Single speed pumps can be modified into three speed pumps by way of an adaptor. Notify this
in your orders.
PUMP SELECTION
It is essential to know the flow rate (Q) and necessary pressure (Hm) value for the
selection of circulation pump. These values are given in the heating project of the
building and circulation pump selection is made according to these values. If no
heating project is available, the following evaluation methods can be applied for
pump selection.
• Full conformity with Regulation for Energy-Performance
Buildings clause 12/6
• Thermal protection
• Counter rotation warning and protection
• Locked rotor detection and fault signal
• Missing phase and phase sequence control
• IP44 protection class

Pump Data
Minimum required suction height in 40°C
ambient temperature at the suction side
of the pump to prevent cavitation noise.
(mWc)
HCPO-Al 6/13
When there is cavitation in a circulation pump, the following problems arise:
Low performance: Since the required flow conditions are not met, pump
cannot create the necessary flow rate and pressure. Upper floors cannot be
heated.
Vibration: Turbulent flow caused by air bubbles causes vibration.
Pump life is reduced: Air bubbles in the system or in the pump corrode the
pump material causes erosion.
Noise: Air bubbles, turbulence and striking of water on surfaces create noise.
HCPO 5/10
When the pressure at the suction end of
the circulation pump is not enough, water
changes phase to turn into gas. Gas bubbles
are carried to high pressure areas by the
flow. Vapour turns into water again and
gas bubbles causes turbulence in the flow
and water strikes the surfaces. This process
is called cavitation.

Do not operate the pump without water.
NEVER LUBRICATE THE PUMP
Rods and bearings of ALARKO circulation pumps are water lubricated and they do not need
maintenance. New or idle pump rods may be throttled due to the pollutants and particles in
the water. In such cases, close the main electric switch. Remove the rotor end cap and rotate
the shaft a few rounds via screwdriver. Put the rotor end cap in place and operate the pump.
Single speed pumps can be modified into three speed pumps by way of an adaptor. Notify this
in your orders.
PIPE CONNECTIONS AND DIMENSIONS
INSTALLATION POSITIONS
NOT PERMITTED
PERMITTED
Automatic Speed Controlled
Pump shaft must not be vertical position.
Pump shaft must be parallel position.
Circulation Pumps
Connect the pump to the installation as shown in the figure by making it parallel to the ground.
Use isolating valves in the inlet and outlet in order to facilitate the removal of pump during repair or
maintenance.
Use a thermic relay when connecting the pump to electric supply.

Pump Data
Minimum required suction height in 40°C
ambient temperature at the suction side
of the pump to prevent cavitation noise.
(mWc)
HCPO-Al 6/13
When there is cavitation in a circulation pump, the following problems arise:
Low performance: Since the required flow conditions are not met, pump
cannot create the necessary flow rate and pressure. Upper floors cannot be
heated.
Vibration: Turbulent flow caused by air bubbles causes vibration.
Pump life is reduced: Air bubbles in the system or in the pump corrode the
pump material causes erosion.
Noise: Air bubbles, turbulence and striking of water on surfaces create noise.
HCPO 5/10
When the pressure at the suction end of
the circulation pump is not enough, water
changes phase to turn into gas. Gas bubbles
are carried to high pressure areas by the
flow. Vapour turns into water again and
gas bubbles causes turbulence in the flow
and water strikes the surfaces. This process
is called cavitation.
