Grundfos EZ Boost Controller and Pressure Transducer Sensor

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.

Grundfos EZ Boost Controller 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)
