The Wilo Stratos-D 50/1-8 is a single phase glandless premium high-efficiency pump with a 0.2kW motor. The Wilo Stratos-D range are twin-head glandless circulator pumps with flanged connections. They are useful in many kinds of heating and cooling systems, including industrial circulation systems. These pumps include a number of energy savings features including a built in flow limiter, which simply limits the amount of liquid the pump will move. The energy efficiency ratings easily exceed the 2015 ErP requirements for high efficiency circulator pumps. There are optional modules available for connection to commercial BMS systems.
