Circulation Pump for Premium, Premium Plus Boiler Series, Tenko TM

The UPS 25/60 is a Grundfos wet rotor circulation pump for heating and hot water applications. Includes a set of union nuts for mounting. 
 
Functional features: 
 
UPS 25/60 is a small-sized circulation pump with virtually silent operation and economical power consumption.
Pump with stator isolated rotor and motor forms a single unit without shaft seals. The impeller, made of heat-resistant composite material, gives the unit anti-corrosion resistance. The motor windings are resistant to blocking current, so it does not need additional protection. For ease of maintenance, the electric motor can be removed without removing the pump from the system. 
 
Features: 
 

• Wide range of parameters 
• High efficiency low noise 
• easy electrical connection 
• high quality materials 
• long service life 

Benefits: 
 
By convenient switch the pump terminal box can be used to set the required motor speed (3 fixed speeds). 
 
Ceramic bearing system ensures long life and quiet pump due to the high hardness and low coefficient of linear expansion of the ceramic. 
Depending on the level of automation, the circulation pump can run continuously, on a timer or adjust to the current needs of the system. 
 
Application: 
 
The circulation pump UPS 25/60 is used for water circulation in heating and hot water supply systems, as well as in floor heating systems 
 
Fluids handled: 
 
The pump handles clean, non-viscous and non-aggressive fluids that do not contain solids or fibers. 
Operating limitations maximum kinematic viscosity of pumped water - 1 mm2 / s (1 cSt) at 20 ° С 
temperature range of pumped liquid - from -25 up to +110°C.
