EBARA VARIABLE SPEED and CONSTANT PRESSURE BOOSTER SYSTEM

UN

The EBARA Hydro Booster system consists of two or moreEVM pumps coupled in parallel and mounted on acommon baseplate, integrally provided with a EBARAHydro Controller electrical cabinet and all the necessarycommon pipe work and fittings. All EBARA Hydro Boostersystem is factory assembled and tested, pre-set accordingto customer requirement. It is ready-to-connect at site.Scope of supply includes instruction manual.

Fully assembled and certified Hydro Booster set type UNgenerally consist of multiple pumps arranged in parallel,mounted on a common baseframe, pipework completewith EBARA microcomputer controller unit, frequencyinverters, pressure sensor and complete with all internalelectrical wiring.

EBARA Hydro Booster system type UN is a variablespeed control booster system utilising advance andproven microcomputer namely EBARA HydroController unit to provide constant pressure to suityour system requirement.

Applications• General water supply i.e schools, hotels, hospitals, high-

rise buildings, etc.• Industrial water supply• Irrigation system for garden, parks, golf courses, etc.• All booster pump station

Pumps2 or more EBARA pumps are arranged for paralleloperation. All parts contact with liquid are of stainless steel.

Baseframe & Common Pipe workGalvanized pipe work enable easy connection to allcommonly used pipe fittings. The pipework is sizedsuitable for maximum hydraulic unit capacity. Check valve

and suitable gate valves are fitted for optimal systemoperation.

Diaphragm Pressure TankA pre-charged diaphragm tank is fitted to the dischargepipe with a compatible Butyl-rubber diaphragm. Generallythis tank serves basic functions of supplying water at avery low flow and minimising effect of water hammering.

Pressure Sensor1-5V to transmit control type signals to the EBARA HydroBooster Controller, located at the discharge side or/suctionside (depend on systems offered).

Frequency ConverterConstant water pressure is achieved due to variablespeed drive made possible by the use of frequencyconverters. To ensure highly reliable EBARA system, eachpump is equipped with frequency converter unit, thusensure optimal operation of pumping system.

Flow SwitchFlow switch is used to enhance system operation byreceiving signal to cut-out pump operation during low-flow or no-flow condition. Thus can be used as dry-runningprotection device.

Ebara ControllerThis micro-processor controller unit is fitted to the HydroBooster Control Panel to control variable speed pumpingoperation. It provides ‘One-touch’ operating possibility tointerpret various signals from pressure transmitter andflow switch, thereby enhance constant pressure systemoperation. In addition, it provides various advanceoperative functions that maintain constant pressure andtrouble-free water supply system.

When water flow is low

When water flow is great

A. When water flow is low1 If water is used, the inner pressure of the pipes drop,

triggering the pressure sensor, and advance pump(Ex: No.1) starts up.

5 If water stops being used, the flow switch is triggered,and advance pump (Ex: No. 1) stops after the requiredtime has elapsed. At this time, the advance pumprotates. (Ex: The advance pump changes from No. 1to No. 2)

6 If water is used again, the inner pressure of the pipesdrops, triggering the pressure sensor, and advancepump (Ex: No. 2) starts up.

10 If water stops being used, the flow switch is triggered,and advance pump (Ex: No. 2) stops after the requiredtime has elapsed. At this time, the advance pumprotates. (Ex: The advance pump changes from No. 2to No. 3.) In the same way, the advance pump rotatesin order from No. 3 to No. 4, No. 4 to No. 5 and No. 5to No. 1, while steps 1 , 5 , 6 , and 10 arerepeated in order.

B. When water flow is great1 If water is used, the inner pressure of the pipes drop,

triggering the pressure sensor, and advance pump(Ex: No.1) starts up.

2 If the flow continues to increase, the rotational speedof advance pump reaches maximum and 2nd pump(Ex: No. 2) starts up.

3 As the volume of water used increases in order, thedelayed pumps starts in order from the 3rd (Ex: No.3) to the 4th (Ex: No. 4), to the 5th (Ex: No. 5), to amaximum of 5 pumps.

4 If the volume of water used decreases, the flow switchis triggered and the delayed pumps shut down inorder, eventually leaving only the advance pumpoperational.

5 If water stops being used, the flow switch is triggered,and advance pump stops after the required time haselapsed. At this time, the advance pump rotates. (Ex:The advance pump changes from No. 1 to No. 2.)

6 If water is used again, the inner pressure of the pipesdrops, triggering the pressure sensor, and 2nd pump(Ex: No. 2) starts up.

7 If the flow continues to increase, the rotational speedof advance pump (Ex: No. 2) reaches maximum and2nd pump (Ex: No. 3) starts up.

8 As the volume of water used increases in order, thedelayed pumps start in order from the 3rd (Ex: No. 4)to the 4th (Ex: No. 5), to the 5th (Ex: No. 1), to amaximum of 5 pumps.

9 If the volume of water used decreases, the flow switchis triggered and the delayed pumps shut down inorder, eventually leaving only the advance pumpoperational.

10 If water stops being used, the flow switch is triggered,and advance pump (Ex: No. 2) stops after the requiredtime has elapsed. At this time, the advance pumprotates. (Ex: The advance pump changes from No. 2to No. 3.)In the same way, the advance pump rotates in orderfrom No. 3 to No. 4, No. 4 to No. 5, and No. 5 to No.1, while steps 1 - 10 are repeated in order.

EBARA VARIABLE SPEED BOOSTER SYSTEM - CONTROLLER

UN

The heart of the system is the EBARA controller unit,which is user-friendly and permits ‘One-touch’ operation.It controls the sequence of pump operation with signalsinput from the pressure sensor and/or flow switch in Auto& Alternate mode. This user-friendly controller unit oper-ates compatible with other electrical components to en-sure smooth function of booster system.

EBARA controller unit generally provides the below‘One-touch’ functioning features:

1 x Power on indicating light1 x Power selector switch (ALT/PAR/Rotation/P1 to P5)1 x Mode selector switch (Auto/Test)1 x Power main on off switch1 x Set switch1 x Function / Monitor switch1 x Buzzer stop switch1 x Alarm reset switch1 x Run switch1 x Stop switch1 x LCD System parameter displays

EBARA VARIABLE SPEED BOOSTER SYSTEM - UNIQUE FEATURE

UN

Unique Feature- Receiving (Water) tank

Note 1. * Short circuit E12-E15, E22-E25 (when using the dual tank system) with the jumper cable (included).2. Water reduction is detected by timer control. Therefore, the empty display may be triggered during

the period when the suction amount is greater than the volume of water flowing into the water tank.

PROTECTION FEATURESAutomatic back up system ensure smooth andcontinuous pumping operation during thebelow malfunction:- electrical leakage,- discharge pressure drop,- inverter tripped

Freezes pump Operation when Low Waterlevel at suction tank. Fault Display for below:- suction tank water level- system interlock- electrical leakage- low discharge pressure. *Option (IN-LINE

BOOSTING mode)

The same operation conditions of the pumping system can beobserved and monitored at remote station with only 2 wire connection.No additional electrical supply is required. Buzzer is provided, anddistance within 500 m is permissible.

Display Items:1)Normal display

Digital : Discharge pressure, Pump Operation Hz (each pump).Operation current (each pump), Voltage.

Others : Electrical source (LED Display).Operation mode (Auto, Test, No. of Pump)System interlock.

2)Fault DisplayDischarge pressure drop (each pump),Inverter fault (each pump),Water level (over-flow, insufficient, shortage conditions).
