UP 10 Comfort pump
Water flowing through 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.
Applications
• Domestic hot-water recirculation systems in single-
and two-family houses
• small heating systems.
Pumped liquids
• Domestic hot water
• non-potable water
• softened water.

Motor
• Insulation class: F
• power consumption: 25 W
• voltage: 115 V
• phase: 1.
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. 140 °F (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
145 psi (10 bar).
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.
Features and options:
• 24-hour timer (15 minute increments)
• continuous ON, OFF
• models with adustable aquastat
95 °F (35 °C) ↔ 150 °F (65 °C).
