Proven pumps from a company you can depend on
Designed to dependably and efficiently deliver high flow rates at low to medium pressures, Grundfos end-suction pumps are suitable for a variety of applications including:
- water supply
- industrial pressure boosting
- industrial liquid transfer
- heating / district heating
Grundfos recognise end suction pumps underpin many critical processes and services, and for this reason we have invested in local stock to provide a Fast Track Delivery scheme so you can now get a replacment pump as soon as next day.
Unsurpassed performance in any application
All are non-self priming single stage, centrifugal pumps with axial suction port, radial discharge port and horizontal shaft.
Each has a back pull out design to facilitate removal of the motor, coupling, bearing bracket (NK / NKG) and impeller without disturbing the pump housing or pipework. This simplifies maintenance and enables servicing of even the largest pumps by a single person with a crane.
Long-coupled NK family
Close-coupled NB family
Connect to the future of intelligent pump systems
Grundfos iSOLUTIONS brings a new era of intelligence to pump systems and water technology with solutions that look beyond individual components and optimise the entire system.
End suction in action
Another chilling example of success
As part of their on going commitment to reduce energy costs, an ice cream factory belonging to one of the world’s largest FMCG companies accepted an invitation from Grundfos to conduct a Pump Audit. This revealed that some pumps were 20 years old and had been installed to run at a constant fixed speed, with flow controlled using a 40% closed discharge valve.
Originally sized at 37kW, a review of requirements showed that although site capacity had doubled since it was first established, modern replacement close coupled Grundfos end-suction pumps of only 15kW could in fact be used. This would have delivered energy savings of around £7k per year.
However, by opting to instead select variable speed Grundfos NBE pumps, the client was able to reduce running speed to 45Hz, saving a further 20% in energy costs and reducing payback to just 12 months.
Radiating confidence and reducing energy
Faced with the increasing challenge of sourcing spares for an obsolete competitor’s pump, the UK’s leading steel radiator manufacturer turned to Grundfos and their approved MRO partner to propose a solution for their paint line pumps. A new Grundfos NKG long-coupled ISO 2858 pump with double seals was proposed and supplied, along with associated pipework and cabling modifications.
As part of the package an invertor that would ensure the 22kW pump ran at 40Hz rather than 50Hz was also provided, reducing electrical energy consumption by 50%. This resulted in a payback time for the new installation of just over 18 months, energy savings of around £17k per year and greatly improved confidence in paint line availability.
The customer is very satisfied and now discussing new end suction projects with Grundfos.
