4. Features and benefits
Features
• Speed-controlled, high-efficiency pump fitted with
electronically commutated motor (ECM) with
permanent-magnet rotor and frequency converter.
• Either externally controlled by digital pulse-width
modulation (PWM) low-voltage signal, LIN bus signal
or internally controlled in constant pressure,
proportional pressure or constant speed mode
defined by the means of a smart operating panel or
factory presetting.
• Smart Hydro Block (SHB): An integrated diverter
valve making the pump able to switch between
central heating and domestic hot water circuits. The
SHB is controlled by the pump.
• Hydronic balancing with Grundfos GO Balance.
• Third generation of the first boiler-integrated,
variable-speed ECM pumps which combines both
validated and newly developed components and
concepts.
• Highly reliable as more than 20,000,000 UPM units
have been installed with success since 2006.
• Fits into existing boiler ranges.
• Cost-optimised and reliably available due to new
established mass production facilities.
• Energy-optimised due to improved hydraulic and
motor efficiency.
Benefits
• Use up to 87% less electrical power than
conventional constant-speed pumps.
• Use up to 68% less electrical power than
conventional speed-controlled pumps.
• Use up to 25% less electrical power than the first
generation of ECM pumps.
UPM3 and UPM3 HYBRID variants
• UPM3 is the first Grundfos high efficiency pump with
the terminal box in front and access to a mechanical
deblocking device.
• UPM3 is the first Grundfos high efficiency pump for
high ambient and media temperature of up to 70 °C /
110 °C.
• UPM3 is the first Grundfos high efficiency, PWM
controlled pump with an EEI below benchmark level
of EEI ≤ 0.20.
• UPM3 is the first Grundfos OEM pump with TE
Superseal connectors for power and signal supply.
• UPM3 AUTO is the first Grundfos self-controlled
pump with constant pressure AUTO
ADAPT
mode,
which can be used in underfloor heating systems.
• UPM3 HYBRID is the first hybrid version of externally
and internally controlled, high efficiency Grundfos
pumps.
• UPM3 LIN is the first Grundfos LIN bus pump for
appliance-integrated communication.
UPM3K
• The UPM3K pump range is designed for condensing
applications with media below ambient temperature.
• The stator housing is CED electrocoated with one
drain hole in two possible positions, as IPX4D.
• The minimum admissible media temperature can be
down to -10 °C.
UPM3S
• The UPM3S pump range is designed for integration
in boilers and other heating appliances with limited
performance up to 6 m / 42 W.
• Its rotor is injection-moulded with PPS bonded hard
ferrite magnetic particles.
UPM3L(K)
• The UPM3L pump range is designed for integration in
boilers and other heating appliances with extended
performance up to 7.5 m / 75 W.
• The ambient temperature is limited to 55 °C.
• The media temperature is limited to 95 °C (TF95).
UPMO
• UPMO pumps are designed for replacement in
systems that use old hydraulic interfaces with UP/
UPO, UPS/UPSO, UPR/UPRO, UPER/UPERO pump
heads.
• The UPMO pump head fits most of the existing small
UP15 housings that are used in IWC or hydro blocks,
as well as customised or standard housings made of
composite, cast iron, bronze or stainless steel.
• UPMO can be used as ErP conform replacement for
asynchronous integrated or stand-alone pumps in
existing heating systems.
• UPMO can be used with internal control mode
constant pressure.
• UPMO is equipped also with PWM interface using
PWM profile A.
• The performance of UPMO pumps might be different
from the performance of the pumps that should be
replaced. The power consumption is significantly
lower, the PWM signal is not compatible. Grundfos
HVAC OEM together with the OEM customer have to
check in a validation process, if successful
replacement is possible.
• UPMO is fulfilling all CE requirements, such as LVD,
EMC & ErP. Space and temperature features suit
most OEM requirements. Therefore it can be used in
most heating appliances without constraints.
