2. Features and benefits
Features
The Medium UPM range offers a number of important
features and benefits for the customer:
• Suitable for heating, solar-thermal systems,
geothermal heat pumps and cooling
• Internally or externally speed-controlled, high-
efficiency pumps with electronically commutated
motor (ECM) with permanent-magnet rotor and
frequency converter
• Proven components based on the second UPM
generation
• Improved motor technology and hydraulics for high
pump efficiency
• Meets all Ecodesign requirements of the ErP
regulation EU/622/2012
• Functional design concentrating on the essentials,
fitting in the smallest space
• Easy operation and convenient setting via external
control signals or button
• Electronics separated from the motor for operation
in condensing environments
• Motor protected against condensed water by means
of drain holes and double-coated wiring
• Fits into the confined space inside boilers and heat
pumps
• Electrical compatibility with existing PWM
controllers
• Low ambient temperature constraints (EN 60335)
• Electrocoated cast-iron housing for the prevention
of inside and outside corrosion
• Low flow noise
• High starting torque for reliable starting
• Suitable for cold antifreeze media containing glycol
or ethanol
• Standard delivery with plug for easy electrical
connection and quick and safe installation
Benefits
• Use up to 80 % less electrical power than
conventional constant-speed pumps.
• Use up to 60 % less electrical power than
conventional speed-controlled pumps.
• Highly reliable, based on a range with more than 1
million units installed with success since 2006.
• Cost-optimised and highly available thanks to the
use of existing mass production facilities.
ErP, Ecodesign regulation in brief
The EU has addressed the climate challenge in a EuP/
ErP directive: Since August 2015, all stand-alone
pumps as well as pumps integrated in boiler systems,
solar systems and heat pump systems must fulfil
Ecodesign requirements, defined in regulation 641/
2009/EC on glandless pumps, which was amended by
622/2012/EC. The regulation has set radically new
standards for energy efficiency.
The essentials
• Glandless pumps integrated in products must have
an energy efficiency index (EEI) of not more than
0.23. The benchmark level is 0.20.
• Stand-alone pumps are measured according to EN
16297-2.
• Integrated pumps are measured according to EN
16297-3, due to their various functions integrated in
many customised hydraulic solutions on the market.
• All pumps integrated in products which generate
and/or transfer heat and all types of media are
included. This means that not only heating systems,
but also solar-thermal and heat pump systems are
affected by the Ecodesign regulation.
• Non-compliant spare pumps for integrated pumps
sold before August 2015 are allowed until January
1st, 2022.
• Pumps designed for recirculation of drinking water
are out of the scope of this regulation.
• Conformity with EU regulations is governed through
mandatory CE marking.
All Grundfos Medium UPM pumps meet the Ecodesign
requirements measured by EN 16297-2 and EN
16297-3:2012.
