12. Technical data
Supply voltage:
1x115V +/-10 %, 60Hz.
Motor protection:
The pump requires no external motor protection.
Enclosure class:
Indoor use only, IP42.
CSA Enclosure Type 2.
Insulation class:
F.
Relative air humidity:
Maximum 95 %.
Maximum discharge pressure:
150 psi (10.34 bar).
Inlet pressure:
Sound pressure level:
43 dB (A).
Ambient temperature:
+32 °F (0 °C) to +104 °F (+40 °C).
Liquid temperature:
+36 °F (+2 °C) to +230 °F (+110 °C).
To avoid condensation in the control box and stator,
the liquid temperature must always be higher than
the ambient temperature.
Maximum glycol concentrations:
50 % glycol @ 36 °F (2 °C).
Hydraulic performance change can be expected.
Watt readings:
Accuracy +/-1 Watt.
Flow indicator:
Provides a relative indication of flow — should not
be used in lieu of a flow meter.
Check valve:
Use of check valve may reduce pump hydraulic
performance (up to -10%).
Use check valve in parallel pumping applications.
Curve conditions:
Test liquid: Airless water.
Curves apply to a density of 983.2 kg/m
3
and a
liquid temperature of +140 °F (+60 °C).
All curves show average values and should not be
used as guarantee curves. If a specific minimum
performance is required, individual measurements
must be made.
Curves apply to a kinematic viscosity of 0.474 cSt.

In domestic hot-water system, it is
recommended to keep the liquid
temperature below +149 °F (+65 °C) to
eliminate the risk of lime precipitation.
