Approvals
cULus Listed; cULus Classified, Water Quality,
Drinking water system component; NSF/ANSI 61/
MH26400/NSF/ANSI 372.

Pump housing Cast iron or stainless steel.
Connection type Flanged.
Glycol
Maximum glycol concentrations with clean water:
50 % glycol @ 36 °F (2 °C). Hydraulic
performance change can be expected.
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.**
Inrush current
Measured on a flicker network according to IEC
61000-3-3:1994 + A1, + A2, Annex B. 115 V: 25.2
A.
Leakage current < 3.5 mA
* 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.
