Sound pressure level 43 dB (A)
Approvals
ETL, NSF/ANSI 61, NSF/ANSI 372, FCC,
Canadian ICES-003.
Complies to limits for class B digital device,
pursuant to Part 15 of the FCC Rules.
Flange-to-flange length 6.5 in (165 mm)
Pump housing Cast iron or stainless steel.
Connection type Flanged.
Systems Closed (F, FR) and open (SF).
Glycol
Maximum glycol concentrations with clean water:
50 % glycol @ 36 °F (2 °C). Hydraulic
performance change can be expected.
Flow indicator
Provides a relative indication of flow – should not
be used in lieu of a flow meter.
Check valve
Use of a check valve may reduce pump hydraulic
performance (up to - 10 %). Use a check valve in
parallel pumping applications.
Curve conditions Test liquid: Airless water.**
* See operating temperatures table. In domestic hot water
systems, keep the liquid temperature below 149 °F (65 °C)
to eliminate the risk of lime precipitation. To avoid
condensation in the control box and stator, the liquid
temperature must always be higher than the ambient
temperature.
** Curves apply to a density of 983.2 kg/m3 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.
