The Grundfos EZ Boost Controller is a control and communication unit especially developed for the BMQE booster pumps in constant pressure applications. It incorporates external signal input for the pressure sensor and a pump status relay for use with devices dependant on pump status. 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:
  • Full control of BMQE pumps
  • Two-way comunication with BMQE pumps
  • Adjustable pressure control
  • Alarm indication (LED) when service is needed
  • Push-button starting, stopping and resetting of BMQE pumps
  • UL Listed, CE
  • NEMA 3R (IP55) Enclosure class

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)



WARRANTY: Products manufactured by Grundfos Pumps Corporation are warranted to the original user only to be free of defects in material and workmanship for a period of 24 months from date of installation, but not more than 30 months from date of manufacture.
