3 EZ BOOST SYSTEM Introduction There are many applications within water supply where it is necessary to increase the system pressure. The Grundfos EZ Boost system is the optimum solution for applications requiring: Sealless pumps Quiet operation and/or Maintenance-free operation. The EZ Boost system offers the following features: Dry-running protection igh efficiency of pump and motor Excellent wear resistance Soft starter Over voltage and under voltage protection Overload protection Over temperature protection. Variable speed Electronic control and communication. Applications Pressure boosting. Water treatment. Pumped liquids Thin, non-explosive liquids not containing abrasive particles or fibers. The liquid must not be able to attack the pump materials chemically or mechanically. Should the density and/or viscosity of the pumped liquid exceed the density and/or viscosity of water, please contact Grundfos. BMQE Pump The pumps used for The Grundfos EZ Boost system are modified SQE submersible pumps. The EZ Boost BMQE pump is an SQE pump with an MSE 3 motor. Pump and motor are centered in the 4 stainless steel sleeve. BMQE pumps are suitable for both continuous and intermittent operation for a variety of pressure boosting applications. BMQE Motor The MSE 3 motors are based on state-of-the-art technology within permanent magnets (PM motor), which accounts for the high motor efficiencies. In addition, the motors have a built-in electronic unit with a frequency converter for variable frequency and soft starting The MSE 3 motors features high efficiency within a wide load range. The high and flat efficiency curve of the PM motor enables the same motor to cover a wide power range as opposed to conventional AC motors. For BMQE pumps, this means fewer motor variants. EZ Boost Controller The BMQE pump features variable speed which is offered through frequency control via the EZ Boost controller. As a consequence, the pump can be set to operate in any duty point in the range between the minimum and maximum performance curves of the pump. Each BMQE pump must be connected to its own EZ Boost controller. It is also possible to operate the BMQE without an EZ Boost controller, though the features offered will be fewer.

14 PRE-INSTALLATION A guide to the EZ Boost System The EZ Boost Constant Pressure System automatically balances water surges and equalizes flow and pressure according to consumption. In other words, the system maintains a constant water pressure in spite of varying water consumption. The pressure is registered by means of the pressure sensor and transmitted to the controller. The controller adjusts the EZ Boost BMQE pump performance accordingly. The EZ Boost Constant Pressure System features: Quick and easy installation: ready-to-use system requiring minimum space igh user convenience: constant pressure regardless of water consumption Easily adjustable pressure level: push button control Continuous control and monitoring of pump operation Integrated dry-running protection Integrated overload protection Integrated protection against over voltage and under voltage Soft start system Fig. 1 A Pressure Stop +7 PSI Start -7 PSI.8 A = Pressure setting Controlling ±3 PSI Dynamic variations ±7 PSI Flow GPM At large flow rates, the pressure will drop quickly and the pump will start immediately and maintain constant pressure. When the system is running, the EZ Boost controller makes small adjustments to the pressure to detect whether there is consumption. If there is none, the pump will simply refill the tank and stop after a few seconds. Function When a tap is opened, the pressure in the tank will start to drop. The system maintains a constant pressure within the maximum pump performance in spite of varying water consumption. The pressure is registered by means of the pressure sensor, which transmits a signal to the controller. The controller adjusts the pump performance accordingly to maintain constant pressure by changing the pump speed. At low flow the pressure will drop slowly. When the pressure in the tank is 7 PSI below the setpoint, the pump will start. When the pressure is 7 PSI above the setpoint, the pump will stop. Even though the EZ Boost controller is controlling the pressure within ±3 PSI, larger pressure variations may occur in the system. If the consumption is suddenly changed, e.g. if a tap is opened, the water must start flowing before the pressure can be made constant again. Such dynamic variations depend on the pipe work, but, typically, they will lie between 7 and 14 PSI. If the desired consumption is higher than the quantity the pump is able to deliver at the desired pressure, the pressure follows the pump curve as illustrated in the far right of fig

15 BMQE pumps connected in parallel When connecting BMQE pumps in parallel as shown in fig. 5, a separate EZ Boost controller must be used on each BMQE. Set the pressure on one BMQE 1 PSI lower than the other. For BMQE pumps connected in parallel, mounted above each other, it is recommended to connect the pipes as shown in fig. 5. This layout ensures that the BMQE pumps are filled with water before starting. Fig. 5 Booster unit with two BMQE pumps connected in parallel, mounted above each other. 2 1 Air escape valve Diaphragm tank EZ Boost controller Isolation valve Pressure gauge Pressure sensor Notes: All BMQE modules are supplied with a non-return valve. BMQE modules connected in parallel may also be installed vertically. As venting problems may arise in such installations, it is advisable to install suitable air vent devices. The BMQE should be positioned with the discharge and air vent at the top when installed vertically. When the maximum flow for BMQE pumps in parallel will exceed 35 GPM, a 4-gallon or two 2-gallon diaphragm tank(s) should be used. 25

16 CASE STORY Being responsible is our foundation Thinking ahead makes it possible Innovation is the essence GRUNDFOS EZ BOOST SYSTEM Luxury 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 6-1 gallon holding tank in a basement 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 3 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. With EZ Boost there are more tank options Typical EZ Boost residential installation owever, R. L. Feezer Construction Inc. solves this problem with Grundfos EZ Boost. According to General 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. Grundfos a world-wide supplier Grundfos offers an efficient world-wide service network.

This EZ Boost System boosted water pressure from the city s main from 2 psi to the 6 psi needed for this restaurant s soda fountains and toilets. 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 BMQE 5A BMQE 1C BMQE 5B-12 3 BMQE 1C-13 The first problem was the city s water main could only supply 2 PSI to the restaurant. The plumber said at least 6 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! Wes recommended the Grundfos EZ Boost System model 22BMQE1-19 which, fortunately, he had in stock. On Wednesday morning, Wes stopped by the restaurant 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.
