For domestic and commercial open or closed loop hot water systems, the Davey SB30-25 offers robust circulation performance in secondary hot water distribution and solar heating circuits. This wet rotor circulator pump is specifically suited for installations where bronze construction provides resistance to corrosion in hot water applications.
Three speed manual selector provides flexibility across operating conditions. Speed 1 at 1150 rpm consumes 70 W at 0.32 A, Speed 2 at 1650 rpm draws 102 W at 0.46 A, and Speed 3 at 2300 rpm consumes 114 W at 0.50 A on 240 V single-phase supply. Maximum head is approximately 5.5 m with flow capability reaching 91.7 L/Min.
Construction features a bronze pump casing with threaded ports and ceramic rotor-shaft assembly. Graphite bearings provide low friction operation, while the composite impeller ensures efficient hydraulic performance. The wet rotor design uses pumped liquid for bearing lubrication, contributing to reliable operation.
Installation is supported through barrel unions with threaded ports for direct pipe work connection. The pump accepts liquid temperatures from -10°C to +110°C and is rated IP44 protection class. A built-in capacitor provides high starting torque, while the integrated overload protection safeguards the motor against electrical faults.
