circulation pump dab DMH, DPH

Pump for circulating hot water in small closed (with increased pressure) or open private and industrial heating systems.

TECHNICAL CHARACTERISTICS

  • Protection degree: IP44 three-phase, IP42 single-phase.
  • Operating range: flow from 1.5 to 78 m3/h, pressure up to 18 m.
  • Liquid temperature range: for three-phase execution: from-10°С to +120°С (for models BPH-DPH 150/340.65 T and BPHDPH 150/360.80 T; BPH-DPH 150-180/280.50 T; BPH-DPH 180/340.65 T; BPH-DPH 180/360.80 T: from-10°C to +110°C).
    for single-phase version: from-10°C to +110°C.
  • Pumped liquid: clean, without solid inclusions and mineral oils, non-viscous, chemically neutral, with characteristics close to water (max. glycol content 30%).
  • Max. operating pressure: 10 bar (1000 kPa).
  • Standard flange connection: DN 40, DN 50, DN 65, DN 80 in PN version 6/PN 10 (4 holes).
  • Flange connection on request: DN 80 in version PN 10/PN 16 (8 holes).
  • Installation: motor shaft in horizontal position.
  • Cable entry: PG 11.

DESIGN FEATURES

Cast iron body and wet rotor motor. The electric motor housing is made of die-cast aluminum.
Flange connections of the pumps have threaded holes for connecting pressure gauges or control sensors.
Impeller – technopolymer, shaft – hardened stainless steel.
Rotor casing and stator sleeve made of stainless steel.
Four-pole asynchronous electric motor for BMH and DMH series pumps, two-pole asynchronous electric motor for BPH and DPH series pumps.
Single-phase circulation pump runs on three speeds at a voltage of 230 V, a three-phase circulation pump at two at a voltage of 230 V and three at a voltage of 400 V. The single-phase version has built-in overload protection. For three-phase design, the motor must be connected to the power source via an external contactor.
An integral check valve is installed in the hydraulic housing of the dual pumps to prevent fluid flow when one of the pumps is not running; A blank flange is also supplied as standard if servicing of one of the two pumps is required.
