High efficiency glandless pumps from KSB

High efficiency glandless pumps from KSB

High-efficiency circulators from the Calio-Therm S NC series are maintenance-free glandless pumps for pumping drinking water in closed circuits, commonly found in large building projects.

Like the other Calio pumps from KSB, the circulators feature a high-efficiency permanent magnet motor. With one-touch operation the flow rate can be adjusted via three speed levels. In the event of a blocked rotor the motor stops automatically, and a fault is indicated. Three LEDs display the operating status.

The screwed connections are available in dimension Rp ½ internal thread (EN 10266) or G 1 ¼ external thread (DIN ISO 228). The maximum flow rate equals 0.7 m3/h. The pump’s maximum head is 1.0 m. The drinking water temperature should measure between +5 °C and +65 °C.

The pump sets are available in four designs and can be supplied with either a plug or a cable. This enables electrical connection without any tools. Apart from its simple standard design, the pump set is also available as a variant with integrated non-return valve and shut-off valve.
