    The Salmson SB 04-15 is the newer model of hot water circulating pump, replacing the Salmson NSB 04-15 and the WILO Star ZA-15 circulator pumps which are no longer manufactured. Cartridges are still available for all three models but in the majority of cases replacing the entire pump is the best option.

    Salmson SB 04-15 single domestic circulator pumps:

    SPECIFICATIONS  
    Flow up to : 0,7 m3/h  Max. service pressure: 10 bar
    Min. pressure suction : 0,2 bar
    Water hardness (TH) : 35 F

    APPLICATIONS
    Heat pump hot water units
    Solar circuits             
    Domestic hot water
     
    When choosing a solar hot water circulating pump based on the pumps head:
               
    The head rating on a pump is a static rating, and applies to the maximum head in an open loop system - such as pumping up to a roof tank. In the case of circulation through a roof panel and back down a return line, once the system is primed the weight of water falling down the return line is equal to the weight of water in the feed line, and essentially the pump only needs to overcome the total pipe friction in the system. When you take this into account the limitation is more to do with pipe length than the height.
     

    When replacing the pump, it is also a good idea to replace the non return valve with an AVG solar rated non return valve . Most manufacturers require the non return valve to protect the circulating pump for several reasons.
