UP10-16
The water-conduction part of the pump is
hermetically separated from the stator with a
stainless steel spherical separator. The motor can
be separated from the pump housing, enabling
easy maintenance and replacement.
UP10-16 is supplied with insulating shells.

Ambient and liquid temperatures
Liquid temperature: 36°F +(2°C) to 203°F +(95°C)
It is recommended to keep the operating
temperature as low as possible (e.g. 140F°(60°C))
to avoid calcium precipitation.
The ambient temperature should always be lower
than the liquid temperature, as otherwise
condensation may form in the stator housing.
Maximum system pressure
All Models: 145 PSI.
Inlet pressure
To avoid cavitation noise and damage to the pump
bearing, at high temperatures the following
minimum pressures are required at the pump
suction port.
Liquid temperature 203F° (95°C) 185°F (85°C)
Inlet pressure 9 ft. (2.8m) 1.6 ft. (0.5m)
4.0 psi 0.7 psi
Performance
Flow Range: 0-3 U.S. GPM
Head Range: 0-5.4 Feet
