Pumped liquids
Depending on type, Grundfos circulator pumps are
designed for the following liquids:
• Potable water
• non-potable water
• water-glycol mixtures
• chilled water
• domestic hot water
• softened water.
If the circulator pump is used for a glycol mixture with a
higher viscosity than that of water, the hydraulic
performance of the pump will be reduced.
Example: 50 % glycol at 68 °F (20 °C) means a
viscosity of approx. 10 cSt and a reduction of pump
performance by approx. 15 %.
When selecting a pump, the viscosity of the pumped
liquid must be taken into consideration.
Ambient and liquid temperatures
The maximum allowable water temperature is
determined by the ambient air temperature as shown
in the table below.
Note: This table refers to all standard products without
timer, control options or other special features.
• If the UP pump is equipped with a timer, the
maximum liquid temperature is 150 °F (66 °C).
• Temperature requirements for pumps with timer,
control or other special features may be found on
their technical data page. See section 6. Technical
data, pages 38-79.
The ambient temperature for standard pumps with a
permissible liquid temperature from 36 °F (2 °C) to
230°F (110 °C) should always be lower than the liquid
temperature, as otherwise condensation may form in
the stator housing.
Maximum system pressure
145 psi (10 bar).
Minimum inlet pressure
The pressure required at the inlet of a pump is a
function of the temperature of the water as shown in
the table below.

Flow range 0-120 gpm (0 - 27.3 m

h)
Head range 0-46 ft (0-14 m)
In a pressure system, the required inlet pressure is the
allowable system pressure.
In a system open to the atmosphere, the required inlet
pressure is the minimum distance the pump must be
located below the lowest possible water level of the
water source (tank, pool, etc.).
