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.   

Features:

• Maintenance-free operation
• Quiet operation
• Variable speed
• Electronic control and communication
• Parallel connection capability
• Dry-running protection
• High efficiency of pump and motor
• Soft starter
• Over voltage and under voltage protection

Grundfos BMQE Sizing Quick Guide

The BMQE pump can be selected by following 3 easy steps:

1. Determine the pressure needed at your maximum flow
2. Determine your current available pressure (inlet pressure)
3. 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)
