Grundfos Pressure Manager
General description
Introduction
Fig. 1 Grundfos PM 1 and PM 2
The Grundfos PM 1 and PM 2 pressure managers are
designed for automatic start/stop control of Grundfos
pumps and other water supply pumps.
PM 1
The PM 1 is suitable for applications where start/stop of
the pump according to consumption is needed. It is the
basic control solution offering start at 1.5 or 2.2 bar.
The PM 1 starts the pump when the start pressure is
reached, and the pump keeps running as long as there
is a flow.
The PM 1 offers dry-running protection and cycling
alarm for increased safety.
PM 2
The PM 2 is the all-round control solution offering
adjustable start at 1.5 to 5 bar. This enables
customisation to different types of installations and
desired comfort level.
The start pressure is set by means of DIP switches
located behind the control panel whereas the current
pressure is indicated on the LED display on the front of
the PM 2.
The PM 2 starts the pump when the start pressure is
reached, and the pump keeps running as long as there
is a flow.
The PM 2 can be optimised for operation with an
external pressure tank by enabling the 1 bar
differential-pressure function.Thisfunctionsignificantly
reduces the number of operating hours of the pump in
installations with pressure tank.
Features
The table below gives a brief comparison of the
features of the PM 1 and PM 2. The main features are
described beneath the table.
User-friendly interface
The PM 1 and PM 2 have a user-friendly interface with
LED indicators showing:
• power on
• pump running
• alarm indication
• pressure indication (only PM 2).
Free position in installation
The PM 1 and PM 2 can be freely positioned in the
installation – vertically, horizontally, or at an angle.
This makes it easier to install the units in confined
spaces and in extensive existing pipework.

General description Grundfos Pressure Manager
The control panel of the PM 2 can be turned 360 ° in
steps of 90 °. It is thus possible to change the
orientation of the control panel depending on the
mounting position. See fig. 3.
Fig. 3 Orientation of the control panel
Flexible power supply
Due to robust electronic components, the PM 1 and
PM 2 can be powered by a generator or other
alternative power supplies.
Rotary outlet connection
The outlet connection of the PM units can be rotated
360 °. See fig. 4.
The inlet connection is an integrated part of the unit
housing.
The units have a built-in non-return valve.
Fig. 4 Rotary outlet connections
Protective functions
The PM 1 and PM 2 incorporate a number of functions
which protect both the pump and the installation.
Protective functions:
• dry-running protection
• cycling alarm
• maximum continuous operating time (30 minutes)
(PM 2 only)
The PM 2 has an auto-reset function which can be used
to automatically restart the pump.
For further information, see section Functions on
page 9.
Adaptability
The PM 2 can be adapted to the individual installation.
Via a number of DIP switches located behind the
control panel, the start pressure can be adjusted from
1.5 to 5 bar. Furthermore, the PM 2 can be set to an
operating mode with 1 bar differential pressure
between start and stop of the pump. This operating
mode is intended for systems with an external pressure
tank.
For further information, see section Functions on
page 9.
Internal pressure tank (PM 2)
The PM 2 incorporates a small internal pressure tank
which minimises the number of starts and stops of the
pump in case of minor leakages.

Applications
Typical applications are water supply systems and
rainwater systems in
• single-family houses
• blocks of flats
• summer houses and holiday cottages
• horticulture and gardening
• agriculture.
Liquids
Clean, thin, non-aggressive and non-explosive liquids
without solid particles or fibres that may attack the unit
mechanically or chemically.
Examples:
• municipal water
• rainwater.
Examples of applications
PM 1 or PM 2 installed in connection with an
SQ pump
When the PM unit is installed downstream from the
pressure tank, the SQ pump is started immediately
when a tap is opened. This means that the pump is
started when there is a flow. In this way the pressure
tank compensates for the pressure drop to be expected
when the pump starts. The pump takes a few seconds
to reach full speed, i.e. pressure.
Fig. 5 Water supply from a borehole – typically at depths
exceeding 8 metres
PM 1 or PM 2 installed in connection with a JP pump
The PM unit and the JP pump constitute a small
waterworks. The pump will be started whenever water
is consumed, due to the pressure drop. If the water
level in the well drops from time to time, the pump may
run dry. In this case, the PM 2 can be used with the
auto-reset function enabled. Then the water supply will
automatically be re-established when the water level
rises again, and the pump is thus able to reprime the
suction line.
Note: The same function can be achieved if the pump
is drawing water from a break tank as long as the pump
is able to self-prime.

Applications Grundfos Pressure Manager
PM 1 or PM 2 installed in connection with a CH pump
If the pump inlet pressure exceeds the start pressure of
the PM unit, the pump will be started due to flow when
water is consumed, i.e. the PM units will still start the
pump when water is consumed even though the pump
inlet pressure is higher than the start pressure of the
unit.
Note that the pump will stop at pmax. = Hmax. + pinlet.
Hmax. is for the pump.
If this pressure causes problems, the PM 2 can be set
to stop at pstart + 1 bar, but only when installed together
with an external pressure tank.
In this case, the pump is operated like a pump with
a conventional pressure switch, but with additional
protection of the pump, i.e. dry-running protection,
cycling alarm, etc.

Installation
Mechanical installation
The PM 1 and PM 2 must be installed on the discharge
side of the pump. The PM units can be fitted directly to
the pump discharge port or between the pump and the
first tapping point.
It is recommended to connect the unit to the piping
system using unions.
Note: No taps must be installed between the pump and
the unit.
If pumping from a well, borehole or similar, always fit
a non-return valve on the suction pipe of the pump.
Location
The installation location must be clean and well
ventilated.
The units must be positioned so that they are protected
from rain and direct sunlight.
Height between PM unit and highest tapping point
The height (H) between the PM unit and the highest
tapping point must not exceed the values in the table
below.
Fig. 8 Installation example
Electrical installation
The electrical installation must be carried out in
accordance with local regulations and standards.
• The electrical installation of the PM 1 and PM 2
must be carried out so that the enclosure class is
maintained.
• Make sure that the PM unit is suitable for the power
supply to which it will be connected.

Grundfos Pressure Manager
Functions
PM 1
The functions of the PM 1 are described below:
Anti-cycling
If there is a minor leakage in the system, or a tap has
not been entirely closed, the PM 1 will start and stop the
pump periodically. In order to avoid cycling, the anti-
cycling function of the PM 1 will stop the pump and
indicate an alarm.
Dry-running protection
The PM 1 incorporates dry-running protection that
automatically stops the pump in case of dry running.
The dry-running protection functions differently during
priming and operation.
Note: If a dry-running alarm has been activated, the
cause should be found before the pump is restarted in
order to prevent damage to the pump.
Dry running during priming
If the PM 1 detects no pressure and no flow within
5 minutesafter ithasbeen connected toa power supply
and the pump has started, the dry-running alarm is
activated. This allows the pump to self-prime.
Dry running during operation
If the PM 1 detects no pressure and no flow within
40 seconds during normal operation, the dry-running
alarm is activated.
PM 2
The PM 2 has the same functions as the PM 1, but
the PM 2 has some additional functions which can be
enabled and disabled with DIP switches located behind
the control panel.
Auto-reset
When the auto-reset function is enabled, cycling and
dry-running alarms will be automatically reset.
Note: The auto-reset function should NOT be enabled
on pumps which cannot self-prime when water returns
after dry-running.
Anti-cycling
To avoid inadvertent starts and stops of the pump in
case of a failure in the installation, the anti-cycling
function can be enabled.
The function will detect cycling if it occurs and stop the
pump with an alarm.
When the PM 2 has been set to start/stop according to
water consumption (default), cycling may occur in the
following situations:
• In case of a minor leakage.
• If a tap has not been entirely closed.
When the PM 2 has been set to start/stop with 1 bar
differential pressure, cycling may occur in the following
situations:
• If the pressure tank has lost its precharge pressure.
• If the size of the pressure tank is insufficient.
If the cycling alarm has been activated, the pump can
be restarted manually by pressing [Reset].
When the auto-reset function is enabled, the pump will
be restarted automatically after 12 hours in alarm
condition.
Note: In case of a very small consumption, the anti-
cycling function may register this as a minor leakage
and stop the pump inadvertently. If this occurs, the
function can be disabled.
Maximum continuous operating time (30 minutes)
When this function is enabled, the pump will be stopped
when the pump has been running continuously for
30 minutes.
The purpose of this function is to avoid unnecessary
water and current consumption, e.g. in case of pipe
fracture or considerable leakages.
Note: When the function is enabled, any consumption
exceeding 30 minutes will cause an alarm, and the
pump will be stopped. If enabled, the auto-reset
function will not restart the pump.

Selection
Selection of Pressure Manager
Thefollowinghelps determinewhich PressureManager
type to select for a given application.
Functions
The PM 1 and PM 2 share some of the same functions,
but the PM 2 offers some additional functions. Among
other things, the start pressure for the PM 2 is
adjustable.
For further information about Functions, see page 9.
Features
A comparison of the features of the PM 1 and PM 2 can
be found in section Features on page 3 where the main
features are also described.
Technical data
The Technical data for the PM 1 and PM 2 can be found
on page 13. The maximum contact loads must be
observed when selecting a PM 1 or PM 2. Furthermore,
the height (H) between the PM unit and the highest
tapping point must not exceed the values in the table
below. See also fig. 8 on page 8.
Selection of pressure tank
Be aware that in systems where small leakages may
occur, a small pressure tank might be required in order
to minimise the number of starts and stops of the pump.
Recommended pressure tank:
PM 1
In systems with a very small consumption, the above-
mentioned pressure tank can be fitted to reduce the
number of starts/stops of the pump.
PM 2
The PM 2 has an internal pressure tank with a capacity
of 0.1 litre which reduces the number of starts/stops of
the pump when there is a very small consumption in the
system. To further reduce the number of start/stops of
the pump, an external pressure tank can be installed.
Tank sizing for PM 2
The PM 2 can be set up for operation with 1 bar
differential pressure, which reduces the pump
operating time. When this operating mode is used,
a pressure tank must be installed.
To find the correct size of the pressure tank, follow the
guidelines below:
The size of the tank can be determined on the basis of
the selection curves in fig. 9.
The selection curves are based on these values:
• Differential pressure Δp = 1 bar
• Number of starts/stops per hour = 20
• Precharge pressure = start pressure x 0.9 bar.
Sizing example
See fig. 9.
• Estimated consumption = 4 l/min.
(point A on the x-axis)
• Start pressure = 3 bar
(point B on the y-axis)
• An 18-litre pressure tank is suitable
(point C).
