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.

Cambodian water plant enjoys 15% energy and water savings

In the Cambodian province of Takéo, the water supply company was doing what it could with the technology it had to supply drinking water to the small city of Doun Kaev and the surrounding 45 villages of about 44,000 people.

Dubai buildings unlock up to 80% energy savings with simple pump swaps

A Dubai building owner is saving 50-80% electricity from the pumps in its air-conditioning systems. With a retrofit, the customer got new, state-of-the-art pump equipment and is providing a better environment to residents. The project is in line with Dubai’s goal of saving 30% of its energy by retrofitting 30,000 buildings by 2030. It all starts with a Grundfos Energy Check.

Easy access to safe, affordable water changes lives in Ugandan villages

After decades of unsafe water access causing sickness and death, fishing villages by Lake Victoria are now getting safe and affordable water with Grundfos Lifelink systems. In one village, diarrhoea cases are on the way to total eradication.

How an old treatment plant became one of Poland's best

Tomaszów updated its wastewater plant with a full-line supply of Grundfos pumps, mixers, optimised tank design and project execution. The city saved 50% energy and improved its water output to be among the best in Poland.

Luxury hotel cuts energy in half and keeps comfort at 100%

In 2010, Midea renovated its headquarters in Shunde, China. The company used another brand of pumps. By 2011, high electricity costs, high noise and other problems from those pumps encouraged the owners to look for a better solution.

Ningbo doses safely and accurately for 1.5 million citizens

Raised on a hillside in the mountains near this urban area of about 4 million in Zhejiang province, the Ningbo Dongqian Lake water plant would supply water to about a third of the city's population.

84 - Adding value in HVAC applications

In this course, you can learn about how you add value in HVAC systems for commercial buildings. We will look at how hydronic systems reduce energy consumption, how integrated solutions and modularised systems improve building performance, and how distributed pumping optimises HVAC system installation.

Solutions for buildings

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.

Solutions for industries

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

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.

Cavitation is the main reason for pump system breakdowns – and the high temperatures in steam boiler systems increase the risk of it occurring. Avoiding cavitation requires considerations of the pressure available at the inlet of the pump in order to make sure that NPSHA > NPSHR.
