Pump Application
The Model NRF/NBF/SSF Booster Pump may be used for water circulating appli‐
cations in hydronic and solar systems. This pump is nonsubmersible, for indoor
use only.
It has not been investigated, nor is it intended for use in swimming pool and ma‐
rine areas.
Glycol mixture statement
• PL pumps can be used to circulate water and glycol mixtures up to a recom‐
mended 30% concentration and 40% for snow melt applications.
• Pump performance is based on 77℉ (25℃). Therefore pumping of glycol
mixtures will affect max performance, depending on mixture concentration
and temperature.
Recommended accessories
• Pump is recommended to be used with clean water systems.
• Dirt or magnetic separators are recommended if the water is high in particu‐
late matter such as iron oxide and/or mineral deposits. Clean water promotes
long pump life.
Operational limits
These pumps are designed to pump liquids compatible with their iron, bronze or
stainless steel body constructions.

Electrical Rating:
If your NBF pump is equipped with a sweat connected pump body, the maximum
operating pressure is limited to 150 PSI (10 bars) or a lower value determined by
the type of solder used and pressure/temperature limitations listed below:
Do not exceed these values.
