Design of this EBARA pump is based on superior engineering and long experience. To prevent trouble and provide satisfactory operation and
long life, it is important to understand the EBARA pump thoroughly by careful study of this manual. If any questions arise regarding this manual,
please direct them to EBARA INTERNATIONAL CORPORATION.
Specifications
Check the nameplate for your pump's head (HEAD), discharge volume (CAPACITY), speed (SPEED), motor voltage and current.
Other specifications are noted in the chart below.

Installation
1. Check the following before beginning installation:
Insulation resistance measurement:
(1) For three phase motor:
With the motor and cable (excluding the power supply connections) immersed in water, use a meggar to measure the
insulation resistance between, the ground wire and each phase of the motor.
Pump Checks
1. Check the following points upon receipt of
your pump:
(1) Check the name plate to confirm that it is the pump
ordered.
(2) Ensure that the pump voltage is the same as the power
at your location.
(3) Check oil level at oil plug.
(4) Check that all plugs and fastening bolts are properly
tightened.
(5) Check that the pump has not been damaged and the
cable glands and cables are in a satisfactory condition.
(6) Check accessories and spare parts against the packing
list.
(7) Check that the impeller turns smoothly by hand.
2. Precautions when operation is suspended:
(1) If operation is to be suspended for 30 days with the pump
immersed in water, measure the insulation resistance of the
motor.
If resistance is over 1 mega ohm, operate pump to prevent
rust from developing on moving parts. Follow the instructions
under OPERATION when pump operation is to be resumed.
(2) For dry storage, clean out pump and store in a dry place.
Follow the instructions under INSTALLATION and OPERATION
when pump operation is to be resumed.
WARNING
Before insulation resistance measurement, always disconnect the power first.
All electrical work should be performed by a qualified electrician and all national and local electrical codes must
be observed.
CAUTION
When measuring the insulation resistance with meggar for motor windings do not test overload protection.
MINIATURE THERMAL PROTECTION (MTP) AND LEAKAGE DETECTOR (LD) ARE USED FOR MOTOR PROTECTION.
MTP AND LD CABLES MUST BE INSTALLED IN CONTROL CIRCUIT.
CAUTION
Measure the insulation resistance. The value should be more than I mega ohm. While making the measurement, keep the
power supply cable off the ground.

Installation
2. Pump Installation
1. Clean the installation area.
2. Under no circumstances should the cable be pulled while
the pump is being transported or installed. Attach a chain
or rope to the grip and install the pump.
3. This pump must not be installed on its side. Ensure that it
is installed upright on a secure base.
4. Install the pump at a location in the tank where there is
the least turbulence.
5. If there is a flow of liquid inside the tank, support the
cable where appropriate (See Fig. 1).
6. Install piping so that air will not be entrapped. If piping
must be installed in such a way that air pockets are
unavoidable, install an air release valve wherever such air
pockets are most likely to develop.
7. Do not permit end of discharge piping to be submerged,
as backflow will result when the pump is shut down.
8. Non-automatic pumps (model DLFU, DLMFU) do not
have an automatic operating system based on built-in
floats. Do not operate the pump for a long time with the
water level near the minimum operating level as the
automatic cut-off switch incorporated inside the motor will
be activated.
To avoid dry operation, install an automatic operating
system, as shown in Fig. 2 and maintain a safe operating
water level.
WARNING
When lifting the pump, use appropriate crane (or hoist) and lift system, check position and tightness of lift system
so that weight of the pump is not UNBALANCED.
Failure to observe this precaution can result in serious accidents.
Handle the cables very carefully. If they are bent or pulled excessively, the cable and the moulded seal may be
damaged, resulting in insulation failure. Also, care is needed to protect cable ends against water intrusion.
CAUTION
Before installation check rotation. Correct rotation is clockwise when viewed from top of motor. Read ELECTRICAL WIRING.

Installation
(2) Cable
a) Never let the end of the cable contact water
b) If the cable is extended, do not immerse the splice in
water.
c) Fasten the cable to the discharge piping with tape or
vinyl strips.
d) Install the cable so that it will not overheat.
Overheating is caused by coiling the cable and exposing
it to direct sunlight.
(3) Grounding
As shown in Fig. 4 ground the green wire (label E). Under
no circumstances should the green wire be connected to
the power supply.
(4) Use short circuit breakers to prevent danger of electrical
shock.
Operation
1. Before starting the pump:
(1) After completing installation, measure the insulation resistance again as described in INSTALLATION.
(2) Check water level.
If the pump is operated continuously for an extended period of time in a dry condition or at the lowest water level, the
thermal protector will be activated.
Constant repetition of this action will shorten pump service life. Do not start the pump again in such a situation until after
the motor has completely cooled.
2. Test Operation:
(1) Model DLFU, DLMFU
a) Turn the operating switch on and off a couple of times to check for normal pump start.
b) Check the direction of rotation. If discharge volume is low or unusual sounds are heard when the pump is operating,
rotation has been reversed. When this happens, reverse two of the three wires.
c) Check amperage, voltage, and head pressure.
Maintenance and Service
Check pressure, output, voltage, current, vibration, and other specifications. Unusual readings may indicate a problem requiring
immediate service. Contact your local EBARA INTERNATIONAL CORPORATION representative as soon as possible.
CAUTION
Check rotation. Correct rotation is clockwise when viewed from top of motor. Pump should be started with gate valve
closed, and then the operator should open the valve gradually.
Fig. 4
WARNING
Disconnect power cable from power source before servicing unit.
Normal maintenance should be done by qualified personnel.

Maintenance and Service
1. Daily inspections:
(1) Check current and ammeter fluctuation daily. If ammeter fluctuation is great, even though within the limits of pump
rating, foreign matter may be clogging the pump. If the quantity of liquid discharged falls suddenly, foreign matter may
be blocking the suction inlet.
2. Regular inspections:
(1) Monthly inspections
Measure the insulation resistance. The value should be more than 1 mega ohm. If resistance starts to fall rapidly even
with an initial indication of over 1 mega ohm, this may be an indication of trouble and repair work is required.
(2) Every 6 months
Check the mechanical seal every six months. If you notice water
mixed with the oil or cloudy texture of the oil, these may be
indications of a defective mechanical seal requiring replacement.
The service life of the mechanical seal can be prolonged by
replacing the oil in the mechanical seal chamber once a year.
When replacing the oil, lay the pump on its side, with filler plug
on top as shown in Fig. 5.
For over 7
1
/2 HP motors, inject turbine oil No. 32 (ISO VG-32) until it overflows. For motors of less than 5 HP, inject the
amount specified in Table 1. Be certain to dispose of oil residue properly.
(3) Preventive maintenance yearly
Conduct an overhaul of the pump annually. These intervals will reduce the possibility of future trouble.
3. Parts that will need to be replaced:
Replace the appropriate part when the following conditions are apparent.
Above replacement schedule is based on normal operating conditions.

whichever shall first occur (the "Warranty Period") the EIC Products to be delivered hereunder against defects in material
and workmanship, under normal use and service when installed, used and maintained in accordance with instructions
supplied by EIC. This is EIC's sole and exclusive warranty. It applies only to EIC Products and specifically excludes Other
