Grundfos UPML – XL GEO OEM circulator pump is made as an extension of the basic UPM GEO up to variable flows to 180W. This circulator pump is particularly suitable for coldwater applications. The pump is designed to be integrated in geothermal heating pumps as well as in heating and air-conditioning systems with remote control of the speed, corresponding to low-voltage PWM (pulse-width modulation) signal input.

Characteristic Features
Glandless circulator pumps integrated in products shall have an energy efficiency index (EEI) of not more than 0.23, the benchmark level being 0.20
Controlled via a digital low-voltage pulse-width modulation (PWM) signal which means that the speed of rotation depends on the input signal. The speed changes as a function of the input profile
A PWM feedback signal provides information about the current performance of the pump, such as current power consumption or various alarm or warning modes
Motor protected against condensed water by means of drain holes and double-coated wiring
Fit for operation in condensing environments thanks to the electronics being separated from the motor
Benefits
Ready for Conversion according to Ecodesign Requirements for 2015
Low Energy Consumption
Great Flexibility for System Configuration due to different control mode options as internally or externally controlled
System and Pump Protection due to various alarm functions
