Smartcirc (N) BUPA

Domestic Circulators with Stainless Steel Housing

Description

Wet rotor circulators designed for use in drinking water systems with constant or weakly variable flow rates. They feature a corrosion-resistant pump housing in stainless steel and are thus suitable for use in drinking water circulation systems.

Only for drinking water up to a temperature of 65 °C and a max. degree of

hardness of 14 °dH (temporary hardness)

The respective speed is set via a rotary switch integrated in the space saving axially integrated terminal box. 3-step switch with manual start-up feature.

The sound pressure level is < 45 dB (A).

Pump housing Stainless steel 1.4308

Impeller PSU - GF 20

Shaft Ceramic

Bearing Ceramic

Bearing plate Stainless steel 1.4301

Can Stainless steel 1.4301
