70M-MS Multi-Stage Pressure Booster
What is it?
It is a constant speed booster pump package utilizing Goulds Water Technology’s multistage, stainless steel pumps.
Stainless steel headers and branch piping are available as an option.
Up to six constant speed pumps can be operated and controlled through the Technologic constant speed pump controller.
How does it work?
The system can be enabled to run automatically from the keypad, or remotely via “dry contact”, or serial communication. Depending upon the water demand, the pumps stage on and off to maintain constant pressure in the building. PRVs (pressure regulating valves) are installed at discharge of each pump to regulate the pressure.
Why use it?
Ideal for high rise buildings requiring high pressure boosts.
Typical application
Suitable for high rise residential and commercial buildings.
Selection Process
Selection of pumps is done through the Intellitronic II pump selector or through applicable pump curves.
Selection of headers and pressure reducing valves may be done through ESP- PLUS or by using appropriate tables. Make sure that the PRV size is not smaller than the pump discharge size. Quotes are generated using the pricing tool ESP-REP.
