BPH - BMH - DPH - DMH Serisi
Description
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.
