Floor Standing Water Pressurisation Systems


The equipment is suitable for systems operating at pressures up to 10 bar(g), the individual pressurisation set should be selected for the required cold fill pressure.

The onscreen information is configured to be clear, using the dot matrix display, and messages are self explanatory.

All SI Pumps pressurisation equipment is suitable for connection to systems with glycol concentrations up to 50%.

The Range

125       Single pump, 2.5 bar(g) maximum delivery pressure
150       Single pump, 5.0 bar(g) maximum delivery pressure
225       Twin pump, 2.5 bar(g) maximum delivery pressure
250       Twin pump, 5.0 bar(g) maximum delivery pressure
