High-efficiency NBE end-suction power for demanding applications

Grundfos NBE end-suction close-coupled pumps are non-self-priming, single-stage, centrifugal volute pumps with axial-suction port, radial-discharge port and horizontal shaft. If you require a pump for demanding applications where flow requirements vary, the NBE is available with a permanent magnet MGE motor up to 11 kW with built-in variable frequency drive and IE5 efficiency to keep efficiency high at all times.

The compact close-coupled pump design means that installation in confined areas is easy. The NBE pump’s main dimensions are designed to the EN733 standard and all our end-suction pumps are tested to ISO909906:2012 Acceptance Grade standards before leaving the factory.

High efficiency

High-efficiency permanent magnet MGE motor with built-in variable frequency drive, available up to 11 kW with IE5 efficiency rating.

Unequalled flow

Optimised hydraulics in housing and impeller for unimpeded liquid flow through the pump.

Sealed operation

O-ring seal between pump housing and cover means no risk of leakage.

Improved corrosion resistance

Housing, impeller and wear ring in different materials for improved corrosion resistance and no sticking elements.

Solutions for industries | Grundfos

Despite rising demands for water and energy, we’re continuing to contaminate or waste our available resources. The availability of the world’s scarce water resources is increasingly limited due to the pollution of freshwater resources caused by the disposal of large quantities of insufficiently treated, or untreated, wastewater into rivers, lakes, aquifers and coastal waters. A total of 80% of all wastewater returns to nature without being properly treated.

Solutions for cities | Grundfos

Worldwide, cities are rapidly expanding — by 2030, 60% of the population is expected to live in urban environments — and the demand for safe and clean water is only growing.

Solutions for buildings | Grundfos

The world’s increasing urbanisation is contributing to significant amounts of energy being used. The global cooling demand alone has doubled in less than 20 years. And water and energy go hand in hand. In general water pumps currently account for a huge amount of the world’s electricity consumption — but with more energy efficient pump solutions, this amount can be heavily reduced.
