BPH-DPH

Wet rotor circulators

Manufacturer Dab Pumps

Pump for circulating hot water in small closed and pressurised or open tank civil and industrial community heating 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 and DMH versions, two pole motor for the BPH and DPH versions. The Single-phase circulator has been designed to work at three speeds - 230V, 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.

TECHNICAL DATA 
Operating range: from 1,5 a 78 m3/h with head of up to 18 metres.
Liquid temperature range: for three-phase version: from -10°C to +120°C (for the models BPH-DPH 150/340.65 T and BPH-DPH 150/360.80 T; BPHDPH 150-180/280.50 T; BPH-DPH 180/340.65 T; BPH-DPH 180/360.80 T: from -10°C to +110°C).
Pumped liquid: clean, free of solids and mineral oils, non viscous, chemically neutral, with properties similar to water. (glycol max 30%).
Maximum operating pressure: 10 bar (1000 kPa).
Standard flanges: DN 80 in PN 6 / PN 10 (4 holes).
Minimum suction pressure: the values are shown in the corresponding tables.
Installation: with HORIZONTAL MOTOR AXIS, on the delivery or return piping, with the suction port as close as possible to the expansion vessel, above the level of the boiler and as far as possible from bends, elbows, branches, to avoid water turbulence, and the consequent noise. Special executions on requests: alternative voltages and frequencies.
DN 80 in PN 10 / PN 16 (8 holes) flange.
Accessories: DN 40, DN 50, DN 65, DN 80 in PN 6 / PN 10 (4 slots).
