3.1 Product description
3.1.1 UPML, UPMXL
UPML, UPMXL circulator pumps are of the canned-rotor type.
Pump and motor form an integral unit without shaft seal, with only
one gasket for sealing and four screws for fastening the stator
housing to the pump housing. The bearings are lubricated by the
pumped medium.
UPML, UPMXL - internally controlled
These circulator pumps are designed for systems with variable
flows, where the pump is internally controlled via an AUTO user
interface. Speed control can reduce the power consumption
considerably. In addition, speed control is required to control the
performance of a system.

UPML, UPMXL - externally controlled
These circulator pumps are remote-controlled via a low-voltage
PWM or 0-10 VDC signal by a system controller integrated in a
boiler or a geothermal heat pump.
