BMQE PumpThe pumps used for The Grundfos EZ Boost system aremodified SQE submersible pumps. The EZ Boost BMQEpump is an SQE pumpwith anMSE 3motor. Pump andmotorarecenteredinthe4”stainlesssteelsleeve.

BMQEpumpsare suitable forbothcontinuousand inter-mittentoperationforavarietyofpressureboostingappli-cations.

BMQE MotorTheMSE3motorsarebasedonstate-of-the-arttechnologywithin permanent magnets (PMmotor), which accountsfor the high motor efficiencies. In addition, the motorshaveabuilt-inelectronicunitwitha frequencyconverterforvariablefrequencyandsoftstarting.

Product Guide EZ BoostTM System

TheMSE3motors featureshighefficiencywithinawideload range. The high and flat efficiency curve of the PMmotor enables the same motor to cover a wide powerrange as opposed to conventional ACmotors. For BMQEpumps,thismeansfewermotorvariants.

Operating conditionsFlow: Max.39USGPM(8.9m3/h)

Head: Max.300ft(91.4m)

Temperature: Max.95°F(35°C)

Operatingpressure: Max.347PSI(23bar)

Inletpressure: Min.8PSI(0.55bar)

Sound-pressurelevel: ThesoundpressureleveloftheBMQE is lower than 74 db[A] at a distance of 3 feet (1meter).

It is recommended by Grundfos that the pump be installed with sound and vibration dampening equipment such as flexible piping adapters and anti-vibration mounting. The pump should not be mounted in or adjacent to living quar-ters. The pump can also be wrapped with sound- proofing insulation to reduce noise (see page 16, EZ Boost System Diagram).

PRE-INSTALLATION

A guide to the EZ Boost SystemThe EZ Boost Constant Pressure System automaticallybalances water surges and equalizes flow and pressureaccording to consumption. In other words, the systemmaintains a constant water pressure in spite of varyingwater consumption. The pressure is registered bymeansof the pressure sensor and transmitted to the controller.ThecontrolleradjuststheEZBoostBMQEpumpperform-anceaccordingly.TheEZBoostConstantPressureSystemfeatures:

• Quickandeasyinstallation:ready-to-usesystem requiringminimumspace

• Highuserconvenience:constantpressureregardlessof waterconsumption

• Easilyadjustablepressurelevel:pushbuttoncontrol

• Continuouscontrolandmonitoringofpumpoperation

• Integrateddry-runningprotection

• Integratedoverloadprotection

• Integratedprotectionagainstovervoltageandunder voltage

• Softstartsystem

FunctionWhena tap isopened, thepressure in the tankwill starttodrop.Thesystemmaintainsaconstantpressurewithinthemaximumpumpperformanceinspiteofvaryingwaterconsumption.

Thepressureisregisteredbymeansofthepressuresensor,which transmits a signal to the controller. The controlleradjusts the pump performance accordingly to maintainconstantpressurebychangingthepumpspeed.

Atlowflowthepressurewilldropslowly.Whenthepres-sureinthetankis7PSIbelowthesetpoint,thepumpwillstart.When the pressure is 7 PSI above the setpoint, thepumpwillstop.

EventhoughtheEZBoostcontrolleriscontrollingthepres-surewithin±3PSI,largerpressurevariationsmayoccurinthe system. If the consumption is suddenly changed, e.g.if a tap is opened, the water must start flowing beforethe pressure can bemade constant again. Such dynamicvariations depend on the pipe work, but, typically, theywillliebetween7and14PSI.Ifthedesiredconsumptionishigherthanthequantitythepumpisabletodeliveratthedesiredpressure, thepressure follows thepumpcurveasillustratedinthefarrightoffig.1.

Pressure boosting made EZ

L-EZ-SL-001 3/06 (US)Subject to alterations

However, R. L. Feezer Construction Inc. solves this

problem with Grundfos EZ Boost. According to Gen-

eral Manager Rusty George, “Traditional tank sizes

are dictated because the pressure boosting pump

has to be mounted inside the tank, requiring a large

tank. With EZ Boost’s external installation, we have

many more options for tank selection, so now we

use a round tank that is easier to install, costs less,

and eliminates expensive rework of door jambs.” The

result was a savings to the homeowner in terms of

the cost of the tank and labor.

CASE STORYLuxury home application

Submitted by

Rusty George, General Manager

R.L. Feezer Construction Inc.

Sykesville, Maryland

Central Maryland illustrates a common problem

when it comes to water pressure for larger homes.

The water level in the area’s 6” rock wells is very deep,

and the yields are inadequate to pump from the well

direct to housing fixtures. Therefore a holding tank

becomes necessary. Often the only place to install a

holding tank is in the basement – particularly in the

North East where sub-zero temperatures are common

during winter.

Installing a 600 - 1000 gallon holding tank in a base-

ment presents another problem….how to get a large

32” wide X 62” long X 62” tall, rectangular holding

tank down a flight of stairs that, halfway, turns left at

a landing and through a 30” doorway. Since the tank

is larger than the door’s opening size, the door’s frame

must be widened to fit the unruly holding tank.

To choose the appropriate EZ-Boost system for your application is simple. 1. Determine how much pressure you need at a given flow.2. Find-out how much pressure you have available (inlet pressure).3. Select a pump from the chart that gives you the difference.

Example: Need 15 gpm with a total pressure of 60 psi. My line pressure is 20 psi, therefore Ineed a boost of 40 psi.The correct selection would be a Model 22 BMQE 05A-80.

EZ Boost Quick Sizing GuideChoosing the appropriate EZ Boost pump for your application is simple:

1. Determine how much pressure you need at your maximum flow.

2. Find out how much pressure you have available (minimum inlet pressure).

3. Select a pump from the chart that gives you the difference.

Example: I need maximum 15 gpm with a total pressure of 60 psi.

My minimum inlet pressure available is 20 psi, so I need a boost of 40 psi.

The correct selection would be a Model 15 BMQE 05A-110.

Wes recommended the Grundfos EZ Boost System

model 22BMQE10-190 which, fortunately, he had in

stock.

On Wednesday morning, Wes stopped by the res-

taurant and found it packed with customers. When

it was convenient he discussed the situation with

the owner who was delighted with the Grundfos EZ

Boost System.

This EZ Boost System

boosted water pressure

from the city’s main from

20 psi to the 60 psi needed

for this restaurant’s soda

fountains and toilets.

Ice cream restaurant application

Wes Blumenauer, CEO

The Blumenauer Corporation

Ocoee, Florida

Wes received a phone call late on a Monday after-

noon from a desperate plumber looking for a pump

to solve a water pressure problem at a Friendly’s Ice

Cream Restaurant in Clermont, Florida.

The first problem was the city’s water main could

only supply 20 PSI to the restaurant. The plumber

said at least 60 PSI was required to operate the soda

machines and flush the toilets.

The second problem was that the restaurant was

slated to open on Wednesday morning – meaning

a solution had to be found, installed and properly

operating in one day!

CASE STORY

Doctor’s offices

With an existing office space, flexible installation options are a welcome advantage. Small offices like this one may not have much mechanical space. The solution: The EZ Boost System was installed above the lay-in ceiling.

Most pumps would be too noisy for this type of installation but not the EZ Boost System. Its variable frequency drive operation is smooth and quiet.

The pressurized diaphragm tank can sit horizontally and the pump is installed inline with the piping system.

APPLICATIONS

Laundry

The EZ Boost System can make it possible to run multiple fixtures without loss in pressure. Compact, clean installation and quiet opera-tion make EZ Boost a perfect choice for laundry applications.

MRI facilities

An MRI facility might need extra pressure to cool the MRI machine. Even with space at a premium, the EZ Boost has been installed in a space as small as a janitor’s closet.

Condominiums

For multiple housing units, EZ Boost can be installed in parallel (each pump must be connected its own controller. Pumps can be installed either horizontally or vertically.

Luxury homes

Comfort and convenience for luxury homes...with an EZ Boost System in place, an upstairs bathroom or shower can have the same water pressure as downstairs. Filling the pool... while taking a bath...while running the dishwasher! is no longer a problem.
