Sistema’s Circulators Pumps for hot water are available 50 Hz and 60 Hz and are built following ERP Standard. The AHW(S) series is a high energy-efficient variable speed circulators, this series of pumps provides 8 different modes selection, such as Highest/Lowest proportional pressure, Highest/ Lowest constant pressure, Highest/ Medium/ Lowest constant speed, and Night version to replace existing fixed circulators in every system.

Sistema’s Hot WaterCirculator Pumps constitute a complete range of 3-speed circulator pumps, available bo th in 50 and 60 Hz. The pumps can be used in both open and closed systems. HH & HW pumps are of the canned-mo tor type, i.e. pump and mo tor form an integral unit without a shaf t seal and with only two ceramic bearing for sea ling. The bearings are lubricated by the pumped liquid.
