Available for varying requirements
The Grundfos UP and UPS Series 100 range of canned rotor circulator pumps is specifically designed for heating systems. The pumps are also suitable for circulation of domestic hot water and for circulation of liquid in cooling and air-conditioning systems. They are available in stainless steel (N), bronze (B) and twin-head (D) versions, as well as the high-efficiency USP2 with advanced control modes.
Does a distributed pumping solution require hydraulic balancing?
No. Because we use small circulators as coil pumps to supply chilled water to each terminal unit (ie. Air handling unit), your entire building will be perfectly balanced at any load.
This also simplifies the design phase, as it is no longer necessary to determine the critical pressure point / index loop when doing the HVAC design. With distributed pumping, your whole system becomes decoupled and each pump is sized to deliver just the right flow.
How is the Capital investment compared to a conventional system with valves?
Because a Grundfos Distributed Pumping system is replacing the valves with coil pumps and reduces the kW size of primary pumps, the Capital Investment will either be the same as a conventional system or around 20% more expensive, depending on the choice of valves in the conventional design.
But the commissioning efforts needed for a distributed pumping solution, will be much less, since there is no need for hydraulic balancing or determination of Set Points (ei. Constant ...
How reliant is a distributed pumping system compared to a conventional system?
Canned-rotor type of circulates have been manufactured by Grundfos since 1959 and integrated speed drives was introduced in 1991, so the design is incredibly reliable and well tested. The current version of MAGNA3 was realeased in 2012 and more than 1 millions units have been sold worldwide for mixed applications.
The expected lifetime of a MAGNA3 is 10 years, but the pump can easily operate longer than this, and is more than able to match the reliance of any type of control valve....
What is Grundfos Distributed Pumping?
Grundfos Distributed Pumping solution is the new revolutionary offering for distribution of chilled water in HVAC applications without the need for pressure regulating valves.
With a distributed pumping solution, you will gain:
- Up to 50% energy savings on your annual pumping power use by using the worlds’ most energy efficient pumps.
- Flow-driven pumping solution that gives you just the right flow to meet your heat load demand.
- Valve-less design, ...
Which Pumps are used for Grundfos Distributed Pumping
Grundfos Distributed Pumping is made possible with our connected pumps that gives optimal and intelligent distribution of chilled water to all terminal units.
For supplying each terminal unit, we utilised our MAGNA3 range as coils pumps. The MAGNA3 is a canned-rotor type, i.e. pump and motor form an integral unit without shaft seal and integrated variable speed drive and IE5 motor giving you the most efficient pump within its' class and it doesn't require maintenance. The MAGNA3 ...
