Wet rotor circulators. They are designed for the circulation of water in civil and commercial conditioning and heating systems. The BPH/DPH (two pole motor) e BMH/DMH (four pole motor) circulator motor shaft can be manually deblock. BPH and BMH are the version with the single motor while BMH e DMH corresponds to the circulators in the twin configuration. Flanged suction and delivery ports. All the models have an air vent plug. The twin version is supplied as standard with an automatic suction type valve incorporated in the delivery port to avoid water recirculating through the unit when it is not running; and a blank flange for servicing either of the two motors. The single phase version works at three speeds, the two phase version works at three speeds.

Cast iron body and wet rotor motor. Die-cast aluminium motor casing.Flanged inlet and delivery mouths, fitted with threaded unions for pressure gauges.Technopolymer impeller, tempered stainless steel driving shaft.Stainless steel protective rotor sleeve and stator sleeve. Four pole asynchronous motor for the BMH and DMH versions, two pole motor for the BPH and DPH versions.The single-phase circulator has been designed to work at three speeds - 230 V, while the Three-phase circulator has been designed to work at two speeds - 230 V and at three speeds - 400 V. Thermal overload protection incorporated in the single phase version.For the three-phase version the motor must be connected to the power supply through an external contactor. An automatic clapet type valve is incorporated into the delivery mouth of the twin version in order to prevent water from recirculating while the unit is not working; a blank flange is also supplied standard if one of the two motors must be serviced.
