Product Overview
Featuring an end-suction structural layout with DN 50 axial suction and DN 32 radial discharge ports, the NB 32-200.1/172 pump processes clean liquid media across active HVAC circuits. Powered by a 3 kW electric motor, the system operates across continuous commercial pumping cycles.
The hydraulic wet-end achieves a rated flow capacity of 302 L/Min with a maximum head rating of 27.85 m. Cast iron housing materials provide solid pressure containment up to 16 bar. The internal assembly houses a stainless steel impeller fitted with bronze wear rings. Net equipment weight is 64 kg.
Power specifications for the NB 32-200.1/172 end-suction pump call for a 415 V three-phase electrical supply rated at 3 kW motor power. Current draw under load measures 9.86 Amps. Operating fluid temperatures span -25°C to 120°C with a maximum working pressure rating of 16 bar. The housing features DN 50 axial suction and DN 32 radial discharge ports.
The NB 32-200.1/172 electric motor carries an IP55 ingress protection rating alongside Class F thermal insulation and integrated PTC thermistors. System maintenance relies on back-pull-out architecture, enabling drive head disassembly while the pump volute stays secured to concrete foundation bases and pipe runs.
Features
- High-efficiency motor selection is configured to match the specific power supply characteristics, pumping environment and liquid properties of each installation.
- Back pull-out design allows complete rotating assembly removal including motor, coupling and impeller without disturbing pump housing or connected pipework.
- EN733 and ISO2858 dimensional compliance ensures interchangeability with other standard end-suction pumps across commercial and industrial installations.
- ATEX Zone 1, 2, 21 or 22 certification available for operation in potentially explosive atmospheres (except E-model variants).
- Integrally cast suction and discharge ports with dedicated vent and drain ports provide direct connection points without additional fittings.
- No baseplate or grouting required to maintain correct shaft alignment and vibration levels within Hydraulic Institute standards.
- Cataphoretic electrocoating on cast iron internal surfaces provides barrier protection against oxidative corrosion in hydronic circulation loops.
