1.2 Introduction
8 8
The Grundfos BMQE Constant Pressure System is a complete
9
pressure boosting system that includes pump, controller, tank,
9
mounting brackets, and pressure sensor. High-quality construction and rugged design ensure low-maintenance and trouble free operation. The system is simple to install and simple to operate as it 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; it provides constant water pressure even while multiple taps are on. The pressure is registered by means of the pressure sensor and transmitted to the controller. The controller adjusts the BMQE pump performance accordingly.
1.3 Delivery and handling
The shipping carton your pump came in is specially designed around your pump during production to prevent damage. As a precaution, the pump should remain in the carton until you are ready to install it. The components are ready for installation. Examine the pump for any damage that may have occurred during shipping. Examine any other parts of the shipment as well for any visible damage.
1.4 Applications
The Grundfos BMQE Constant Pressure System is intended for large residential & light commercial pressure boosting applications such as:
• medical offices
• restaurants
•homes
• condos
• irrigation
• grocery
• other boosting applications.
1.4.1 Pumped liquids
The BMQE must not be used for the transfer of flammable liquids such as diesel oil, petrol or similar liquids. The BMQE is suitable for pumping thin, clean, non-aggressive, non-explosive liquids, not containing solid particles or fibers. The BMQE is suitable for pressure boosting clean, cool, potable water. The liquid must not attack the pump materials chemically or mechanically.
The temperature of the pumped liquid must not exceed + 95 °F (+ 35 °C).

1.6 How the system functions
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 BMQE 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 pipework, 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 (illustrated at the far right of fig. 1).
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 BMQE 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.

1.9 Overview of built-in protections
1.9.1 Run-dry protection
The BMQE pumps are protected against dry-running. In case of dry-run, the BMQE will stop after an accumulated time of 5 seconds thus preventing a burnout of the motor. After a dry-running alarm, the pump restarts automatically after 5 minutes.
1.9.2 Overload p ro tect io n
Exposure of the BMQE pump to heavy load causes the current consumption to rise. The motor will automatically compensate for this by reducing the speed. If the speed drops to 30 % of the rated speed, the motor will be cut out. If the rotor is being prevented from rotating this will automatically be detected and the power supply cutout. Consequently, no extra motor protection is required.
1.9.3 Over-voltage and under-voltage protection
Over voltage and under voltage may occur if the voltage su pply is unstable. The integrated protection of the BMQE motor protects the motor if the voltage falls outside the permissible voltage range.
• With a rated voltage of 200 - 240 V, 60 Hz, the pump will be cut out if voltage falls below 150 V or rises above 280 V.
• With a rated voltage of 110 - 1 15 V, 60 Hz, the pump will b e cut out if voltage falls below 75 V or rises above 150 V.
The motor is automatically cut in when the voltage is again within the permissible voltage range. Therefore, no extra voltage protection relay is required.

3.2 Mechanical installation
Note
3.2.1 Pre-installation checks
Before installation, the following checks should be made:
1. Confirm pump type
Check that the pump type stated on the nameplate fitted to the module sleeve corresponds to your order.
2. Check electricity supply
The motor voltage and frequency details stated on the nameplate should be compared with the actual electricity supply available.
3.2.2 Location of installation
The sound pressure level of the BMQE is <74 db[A] at a distance of 3 feet (1 meter). 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.
Like most mechanical equipment, this system can create noises and vibrations. Grundfos recommends that the BMQE pump should not be mounted in or adjacent to living quarters.
The pump should not be mounted in or adjacent to living quarters. The pump can also be wrapped with sound proofing insulation to reduce noise.
3.2.3 Positioning the pump
The GRUNDFOS BMQE pump is supplied with a built-in non-return valve. An arrow on the BMQE sleeve shows the direction of liquid flow through the pump (fig. 3).
The BMQE is suitable for both vertical and horizontal installation; however, the discharg e port should never fall below the horizont al plane. See fig. 4.
The BMQE must be installed with the air relief vent in the 12 o’clock position when installed horizontally and when installed in the vertical position, the air vent must be at the top of the unit.
Fig. 3 Arrow showing direction of liqu id flo w throug h pump
In situations where multiple BMQE pump power cables are run parallel in wiring trays or conduit and less than 12 inches apart, the possibility for undesired communication between units exists. When this occurs, intermittent or continuous NO CONTACT is typically seen. Other unexpected errors may also be seen.
There are two ways to eliminate the possibility of cross communication:
1. Physical separation of the cables – maintain a minimum of 12 inches between pump power cables, and never place more than one cable in a conduit.
2. Use shielded cable – the use of shielded cable prevents cross communication between parallel cables and allows sharing of conduit and cable trays. Tie the cable shield to ground only at the BMQE controller panel.

3.3 Electrical installation
Warnin g The electrical connection should be carried out
by an authorized electrician in accordance with local regulations.
Warnin g Before starting work on the BMQE controller or
BMQE pump, make sure that the electricity supply has been switched OFF and that it cannot be accidentally switched on.
The BMQE must be grounded. The BMQE controller must be connected in accordance with the local rules and regulations.

Warnin g IMPORTANT: The ON/OFF button on the BMQE
controller must not
be used as a safety switch
when installing and servicing the pump.
Fig. 4 Installation positions
3.2.4 Power line communication
The communication between the BMQE controller and the BMQE pump is via the power supply cable. This communication principle is known as power line communication.
Using this principle means that no additional cables to the pump are required. The communication of data is effected by means of a high-frequency signal transmitted to the power supply cable.

Warnin g The BMQE must never be connected to a
capacitor or to another type of control box than BMQE controller.
The BMQE must never be connected to an external frequency converter.
Warnin g Reduced risk of electric shock during operation
of the BMQE system requires the provision of acceptable grounding. If the means of connection to the supply connected box is other than grounded metal conduit, ground the pump back to the service by connecting a copper conductor, at least the size of the circuit supplying the pump.
Rain-tight or wet location hubs that comply with the requirements in the standard for Fittings for Conduit and Outlet Boxes, UL514B, are to be used. Suitable devices for BMQE controller are rated with enclosure type 3, 3R, 3S, 4, 4X, 6 or 6P.
