The Centrifugal Pump
In 1689 the physicist Denis Papin invented the centrifugal pump and today this kind of pump is the most used around the world. The centrifugal pump is built on a simple principle : liquid is led to the impeller hub and by means of the centrifugal force it is flung towards the periphery of the impellers.
The construction is fairly inexpensive, robust and simple and its high speed makes it possible to connect the pump directly to an asynchronous motor. The centrifugal pump provides a steady liquid flow, and it can easily be throttled without causing any damage to the pump.
If a pressure difference occurs in the system while the centrifugal pump is not running, liquid can still pass through it due to its open design.
The difference demands on the centrifugal pump’s performance, especially with regard to head, flow, and installation, together with the demands for economical operation, are only a few of the reasons why so many types of pump exist.

Grundfos end-suction pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation.
Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications requiring reliable and cost-efficient supply. End-suction pumps are used in five main areas of application: water supply, industrial pressure boosting, industrial liquid transfer, HVAC and irrigation by Grundfos end-suction pumps
The Grundfos NB/NBG pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. The NB/NBG range consists of close-coupled pumps with their main dimensions in accordance with either EN733 or ISO2858.

The Grundfos Pumps horizontal multistage pump CM (=Centrifugal Modular) has been created with compactness and modularity as two of its central features, making numerous configurations possible. The pump is basically composed of a series of interchangeable modules, all of which have been designed to work together seamlessly, no matter what the application.
The pumps are of the close-coupled type.
The difference between the CM and the CME pump ranges is the motor. CM pumps are fitted with mains-operated motors, whereas the motors for CME pumps have an integrated frequency converter.
Both CM and CME Grundfos Pumps have mechanical shaft seals.
The CM and CME Grundfos Pumps are available in cast iron or stainless steel (AISI 304/DIN 1.4301 stainless steel, which is for water and non-corrosive liquids, and AISI 316/DIN 1.4401 stainless steel, which offers a high degree of corrosion protection against aggressive liquids).
Applications of Grundfos Pumps
The CM or CME Grundfos Pumps is a multi purpose pump for both industry and water boosting in general.
It is compact, noiseless, reliable and flexible, and this make it an optimal solution for installation and interaction with other components in small and large systems or as a stand-alone pump.

Commissioning
- If pumps with 2900 rpm are installed inside residential buildings, then corresponding noise reducing measures are to be implemented.
- Pump curves and specific motor powers depend on the respective fluid being pumped. Pump curves and power vary considerably when fluids are conveyed that differ from water in thickness and/or viscosity. For this, please observe the table “Recommended limit values for dimensioning”.
The recommended limit values for dimensioning are calculated as follows:
Qoptimum (volume flow at which the pump reaches its best efficiency), to be read from the individual pump curve; factors Qmin and Qmax , to be taken from the table “Recommended limit values for dimensioning”.Qmin dimensioning = Qmin x Qoptimum
Qmax dimensioning = Qmax x Qoptimum
Example: Size NL 32-125
Qmin = 0.3 x 8 = 2.4 m3/h
Qmax = 1.2 x 8 = 9.6 m3/h - Load-sensitive pump output
All Wilo standard pumps are equipped with IEC standard motors. The Wilo control devices are suitable for automatic load-sensitive speed control of pumps that are driven by any standard motors of conventional manufacture. - Main/standby mode

General notes – ErP (ecological design-) directive
- The benchmark for most efficient water pumps is MEI ≥ 0.70
- The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.
- The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.

Grundfos’ new range of GHP (Grundfos Hygienic self-Priming) pumps takes efficiency and durability to new levels in sanitary processes.
The pumps are based on the well-known HILGE technology and are further optimised to offer reliable operation even under the tough conditions encountered in cleaning processes.
The single-stage self-priming GHP pumps combine the best of the F&B-HYGIA end-suction pumps with the reliable HILGE technology. The result is an optimised pump range that comes with increased efficiency compared to traditional side-channel pumps and can be counted on for long operational life.
One pump – More applications
Due to the robust construction of the new GHP pumps they are able to handle liquids with a high content of air as is the case in CIP return systems.
In effect, this means that the same pump can be used for product conveyance as well as for the cleaning processes. Compared to side-channel pumps, GHP pumps are also less sensitive to handling products containing particles.
Low noise operation
The GHP pumps feature a new, unique hydraulic technology that allows the impeller to be adjusted to accommodate exact duty-point requirements.
This translates into a noise level significantly lower than compared to traditional side-channel pumps.
Specially designed for sanitary applications
The all-stainless steel GHP pumps have been specially designed for trouble-free operation in sanitary processes such as:
- Cleaning processes (CIP return)
- Evacuation of tanks and pipes
- Pumping liquids with a high gas content
- Pumping liquids in Food and Beverage industries.
