Description
Grundfos 30 BMQE 05B-90 Ez Boost Pump 1/2 hp (230V) – 91128531
The Grundfos BMQE Booster Pump is the heart of the EZ Boost System. A complete system requires a pressure relief tank, pressure sensor and controller. The BMQE pump’s state-of-the-art motor provides high efficiency, variable speed, quiet operation and soft starting. The EZ Boost has built-in safeties and the small footprint allows for either horizontal or vertical installations.
The EZ Boost Controller governs the BMQE pump’s variable speed. Consequently the pump can be set to any duty point from minimum to maximum.
NOTE: Pump must be placed in area that will not freeze, as this will cause damage to the pump. Placing a pump in an area that is susceptible to freezing, WILL void the Grundfos warranty.

Grundfos BMQE Sizing Quick Guide
The BMQE pump can be selected by following 3 easy steps:
- Determine the pressure needed at your maximum flow
- Determine your current available pressure (inlet pressure)
- Select a pump from the chart that gives you the difference (desired pressure – available pressure = difference)
Example: I need maximum 15 gpm with a total pressure of 60 psi. My current pressure available is 20 psi, therefore, I need a boost of 40 psi. The correct selection would be a Model 15 BMQE 05A – 110. (See highlighted selection in chart below)
