The A/B/D Series, engineered by DAB, is a wet rotor electronic circulator pump that is powered by a two-pole asynchronous motor. This motor is intended for three-speed operation, single-phaseversion, and two speed operations. It is also equipped with a Technopolymer impeller and tempered stainless steeldriving shaft which is attached on graphite brushings, lubricated by the pumped liquid. In addition, they have flanged vents, supplied with threaded connectors for the controlling of gauges.
The wet rotor electronic circulator pumps are built with a pump body enclosed in cast iron, with its motor casing in a die-cast aluminum. Furthermore, they are available in a twin version, where an automated clapet type valve and blank flange are present.
