Product Overview
Specified for commercial building services, process water loops, and district cooling infrastructure, the NB 80-200/188 end-suction centrifugal pump incorporates DN 100 suction and DN 80 discharge flanged ports. The end-suction volute design connects directly to suction line headers and concrete foundation bases.
At nominal operational speed, hydraulic output provides 3038 L/Min flow throughput alongside a maximum head limit of 40.66 m. Structural construction incorporates an EN-GJL-250 cast iron body with cataphoresis surface finish. Internal components feature a stainless steel impeller and BQQE seal. Total net weight stands at 290 kg.
The NB 80-200/188 electric motor operates on a 415 V three-phase supply drawing 56.0 Amps rated current at 30 kW output power. Fluid handling parameters accommodate liquid temperatures between -25°C to 120°C up to 16 bar system pressure. Line connection uses opposite DN 100 inlet and DN 80 outlet flanged ports.
Enclosure protection on the NB 80-200/188 model meets IP55 standards while motor windings feature Class F insulation and PTC thermistor protection relays. Maintenance technicians can extract the drive unit using back-pull-out access without removing the cast iron volute casing from connected plant room piping manifolds.
Features
- Housing, impeller and wear ring use dissimilar material pairings to prevent galling and ensure no sticking elements during extended standby periods.
- 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.
