Standard Circulating PumpsProduct review

Range: Wilo-TOP-S

>Single-head pumps:

• Single stage wet rotor pump with flanged

connection. Preselectable speed stages for

capacity adjustment.

>Applications:

• Pumps with cast iron body for hot water

heating systems of all kinds, air conditio-

ning, closed cooling circuits, industrial cir-

culation systems.

>Special features/product advantages:

• Pre-selectable speed stages for manual ca-

pacity adjustment

• Automatically vented

• Simple installation

• Quiet, maintenance free
