DAB Single circulator pump with a 2-pole motor for circulating water in civil and industrial community heating and air-conditioning systems.
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 version, two pole motor for the BPH version. The Single- phase circulator has been designed to work at three speeds - 230V, while the Threephase 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.
Protection level: IP 44 Operating range: from 1.5 to 78 m3/h with head up to 15 metres. Liquid temperature range: for three-phase version: from -10°C to +120°C (for the models BPH 150/340.65 T and BPH 150/360.80 T; BPH 150-180/280.50 T; BPH 180/340.65 T; BPH 180/360.80 T: from -10°C to +110°C). For single-phase version: from -10°C to +110°C. Characteristics of pumped liquid: clean, free from solids and mineral oils, non viscous, chemically neutral, close to the characteristics of water (max. glycol 30%). Maximum operating pressure: 10 bar (1000 kPa).
