5. Operating conditions
General recommendations
Liquid temperature
In cooling applications condensation may occur on the
surface of the pump. In certain cases it is necessary to
mount a drip tray.
Location
The pump is designed for indoor installation.
Always install the pump in an dry environment where it
will not be exposed to drops or splashes, for example
water, from surrounding equipment or structures.
As the pump contains stainless-steel parts, it is
important that it is not installed directly in
environments, such as:
• Indoor swimming pools where the pump would be
exposed to the ambient environment of the pool.
• Locations with direct and continuous exposure to a
marine atmosphere.
• In rooms where hydrochloric acid (HCl) can form
acidic aerosols escaping from, for example, open
tanks or frequently opened or vented containers.
The above applications do not disqualify for installation
of MAGNA3. However, it is important that the pump is
not installed directly in these environments.
Ambient conditions
Ambient temperatures below 0 °C require the following
conditions:
• The media temperature is +5 °C
• The media contains glycol
• The pump runs continuously and does not stop
• For twin-head pumps cascade operation every 24 h
is mandatory.
Maximum operating pressure
PN 6: 87 psi (6 bar / 0.6 MPa)
PN 10: 145 (10 bar / 1.0 MPa)
PN 12: 175 psi (12 bar / 1.2 MPa)
Note: Not all variants are available in all markets.
Test pressure
The pumps can withstand test pressures as indicated
in EN 60335-2-51. See below.
• PN 6: 104.4 psi (7.2 bar / 0.72 MPa)
• PN 10: 175 psi (12 bar / 1.2 MPa)
• PN 6/10: 175 psi (12 bar / 1.2 MPa)
• PN 12: 175 psi (12 bar / 1.2 MPa).
Not all variants are available in all markets.
During normal operation, do not use the pump at
higher pressures than those stated on the nameplate.
The pressure test has been made with water
containing anticorrosive additives at a temperature of
68 °F (20 °C).
