Delivered on a common base plate, completely assembled and tested before it leaves the factory and ready for connection of water and electricity. All pumps are Grundfos CME pumps with integrated frequency drives connected in parallel and operated in cascade. The booster maintains a constant pressure through continuous adjustment of speed of the pumps and starting and stopping the pumps to meet the required flow. The system consists of: | 2 horizontal multistage pumps with integrated frequency converter, type CME5-4 A suction and a discharge manifold in EN/DIN 1.4571/ AISI 316 TI One non-return valve per pump placed on the discharge side as standard. Two isolating valves and a clamp ring per pump for easy service and inspection of the pumps. Pressure sensor and gauge. CU323 Pump controller for controlling parallel coupled pumps in cascade. | | --- | [![Request a Quote NOW ](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/4260356/8a1894ae-691c-4d95-9910-ab896e6efdd5.png)](https://hubspot-cta-redirect-na2-prod.s3.amazonaws.com/cta/redirect/4260356/8a1894ae-691c-4d95-9910-ab896e6efdd5) **SPECIFICATION INFORMATION                                                                      ** | Product name | HYDRO MULTI-B/E 2 CME5-4 | | --- | --- | | Product No. | 91149111 | | EAN | 5.71149E+12 | | Technical |   | | Rated flow | 49.3 US gpm | | Min flow system | 7.04 US gpm | | Rated head | 145 ft | | Head max | 174.9 ft | | Main pump name | CME5-4 | | Main pump Number | 99450843 | | Number of pumps | 2 | | Model | A | | Materials |   | | Pump | EN-GJL-200 | | Manifolds | EN/DIN 1.4571/ AISI 316 TI | | Installation |   | | Maximum operating pressure | 145 psi | | Pipe connection | 2NPT | | Liquid |   | | Pumped liquid | Water | | Liquid temperature range | 32 .. 140 °F | | Liquid temperature during operation | 68 °F | | Density | 62.29 lb/ft³ | | Electrical data |   | | Power (P2) main pump | 2 HP | | Main frequency | 60 Hz | | Rated voltage | 3 x 208-230 V | | Starting main | electronically | | Rated current of system | 11.2 A | | Controls |   | | Control type | E | | Operation unit | CU323-2 | | Tank |   | | Diaphragm tank | No | | Others |   | | Net weight | 255 lb | | Gross weight | 371 lb | | Product range | NAMREG | | Custom tariff no. | 8413.70.2040 | ![Blueprint](https://www.hurleyengineering.com/hs-fs/hubfs/Blueprint.jpg?width=640&name=Blueprint.jpg "Blueprint") ## Hurley Engineering Service Commitments **All Grundfos MPCE Booster Systems** - **HURLEY IS THE AUTHORIZED SERVICE PROVIDER FOR ALL MODELS OF GRUNDFOS CBS BOOSTER SYSTEMS** - **EXTENDED WARRANTY SERVICE.

We use Grundfos Booster systems for multiple applications on our campus including boiler feed, domestic water boosting, and irrigation supply. Grundfos systems are the most reliable and easy to operate in the industry. In 12 years of operation we have not had any failures or repairs. Our Grundfos representative, Hurley Engineering, provides exemplary service and provides complimentary checks on the systems  on a semi-annual basis. ###### Dave K - Central Washington University We have had tremendous success replacing aging booster systems in all types of buildings with Grundfos Booster Systems. Our projects have been as small as a single booster in small commercial spaces to the largest city high rises. Grundfos has a complete selection of booster systems and working with Hurley Engineering to size the right equipment for the correct application is always a professional a pleasurable experience. Hurley Engineering also always goes above and beyond helping with design assistance, energy rebates, and start up services. Fantastic Team!   ###### Kelly K.MacDonald Miller - [**](https://www.facebook.com/sharer/sharer.php?u=https://www.hurleyengineering.com/multi-b-91149111-2cme5-4-1x208-230&title=MULTI%20B%2091149111%202CME5-4%201X208-230&description=HYDRO%20MULTI-B%202%20CME5-4%20Pressure%20booster%20system%20designed%20and%20manufactured%20by%20Grundfos.%20Delivered%20on%20a%20common%20base%20plate,%20completely%20assembled%20and%20tested%20before%20it%20leaves%20the%20factory%20and%20ready%20for%20connection%20of%20water%20and%20electricity.) - [**](https://twitter.com/intent/tweet?source=https://www.hurleyengineering.com/multi-b-91149111-2cme5-4-1x208-230&text=MULTI%20B%2091149111%202CME5-4%201X208-230%20-%20https://www.hurleyengineering.com/multi-b-91149111-2cme5-4-1x208-230) - [**](http://www.linkedin.com/shareArticle?mini=true&url=https://www.hurleyengineering.com/multi-b-91149111-2cme5-4-1x208-230&title=MULTI%20B%2091149111%202CME5-4%201X208-230&summary=HYDRO%20MULTI-B%202%20CME5-4%20Pressure%20booster%20system%20designed%20and%20manufactured%20by%20Grundfos.%20Delivered%20on%20a%20common%20base%20plate,%20completely%20assembled%20and%20tested%20before%20it%20leaves%20the%20factory%20and%20ready%20for%20connection%20of%20water%20and%20electricity.) - [**](https://plus.google.com/share?url=https://www.hurleyengineering.com/multi-b-91149111-2cme5-4-1x208-230) Copyright © 2026 Companydomain.com.
