Installation

Receiving inspection

Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, file a claim immediately with the company that delivered the pump. If the manual is removed from the packaging, do not lose or misplace.

Storage

Any product that is stored for a period longer than six (6) months from the date of purchase should be bench tested prior to installation. A bench test consists of, checking the impeller to assure it is free turning and a run test to assure the motor (and switch if provided) operate properly.

Before Installation

Insulation resistance measurement With the motor and cable (excluding the power supply cable) immersed in water, use a megger to measure the insulation resistance between ground and each phase of the motor, and again between each phase of the

barmesapumps.com

motor. The megger should indicate an insulation resistance of not less than 20 mega ohms. While making the measurement, keep the power supply cable off the ground. We

recommend that an auxiliary pump be kept on hand in case of emergency.

Installation

WARNING

should cable be pulled while the pump is bein g t r ansporte d o r installed. Attach a chain or rope to the grip and install the pump.

1.This pump must not be installed

on its side or operated in a dry condition. Ensure that it is installed upright on a secure base.

2.Install the pump at a location in

the tank where there is the least turbulence.

Under no circumstances

3.If there is a flow of liquid inside

the tank, support the piping where appropriate. 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.

4.Do not permit end of discharge

piping to be submerged, as backflow will result when the pump is shut down.

WARNING

(models 2AHS), have an automatic operating system bump operating water leve l n e ar the minim um operating level as the automatic cutoff switch incorporated inside the motor will be activated. To avoid dry oper atio n, ins ta ll an auto m atic operating system, as shown in Figure 1 and maintain a safe operating water level (C.W.L.: continuous water level = 90 mm).

5.For automatic pumps (models

2AHS-A), install the floats as shown in figure 2. The pump may not start if a floats switch touches the wall of the water tank or the piping. Install the floats so that this will not happen.

C.W.L.

Wiring:

a) Wire as indicated for the

appropiate start system as shown in figure 3.

b) Loose connections will stop the

pump. Make sure all electrical connections are secure.

Cable:

WARNING

the cable contact water.

d) If the cable is extended, do not

immerse the splice in water.

e) Fasten the cable to the discharge

piping with tape or vinyl strips.

f) Install the cable so that it will not

overheat. Overheating caused by coiling the cable and exposing it to direct sunlight.

Grounding:

Connect the green wire to ground. Under no circumstances should the green wire be connected to the power supply.

DANGER

c) Never let the end of

U s e s h o r t c i r c u i t breakers to prevent danger of electrical shock.

Operation & Maintenance

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 motor 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.

Test operation

Automatic (2AHS-A) and nonautomatic (2AHS) pump:

1) Turn the operating switch on and off a couple of times to check for normal pump start.

For the 2AHS-A:

Floating switch must be raised for the pump to start.

2) Next, check direction and rotation.

barmesapumps.com

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 wires.

Monthly inspections: Measure the insulation resistance. The value should be more than 1M ohm. If resistance starts to fall rapidly even with an initial indication of over 1M ohm, this may be an indication of trouble and repair work is required.

Annual inspections: To extend the service life of the mechanical seal, replace the oil in the mechanical seal chamber once a year. Water mixed with the oil or cloudy textures are indications of a defective mechanical seal requiring replacement. When replacing the oil, lay the pump on its side with filler plug on top. Inject suitable amount turbine oil no. 32 (ISO VG-32).

Inspections at 3-5 year intervals: Conduct an overhaul of the pump. These intervals will preclude the possibility of future trouble.

Parts that will need to be replaced: Replace the appropriate part when the following conditions are apparent. See figure 4. (Note: replacement schedule is based on normal operating conditions)

Disassembly

Maintenance

Check pressure, output, voltage, current and other

specifications. Unusual readings may indicate. Refer to Troubleshooting and correct as soon as possible.

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.

When disassembling pump, have a piece of cardboard or wooden board ready to place the different parts on as you work. Do not pile parts on top of each other. They should be laid out neatly in rows. The o-ring and gasket cannot be used again once they are removed. Have replacement parts ready. Disassemble in the following order, referring to the sectional view.

source before disassembly.

1. Remove pump casing bolts, raise the motor section and remove pump casing.

2. Remove shaft head bolt and impeller.

3. Remove oil filler plug and drain lubricating oil.

4. Remove intermediate casing bolts and intermediate oil chamber. (Remember that any lubricating oil remaining in the mechanical seal chamber will flow out.)

5. Carefully remove mechanical seal, taking care not to scratch sliding surface or motor shaft.

Be sure to cut off power

Assembly

Re-assemble in reverse order of disassembly. Be careful of the following points:

6. During re-assembly, rotate the impeller by hand and check for smooth rotation. If rotation is not smooth, perform steps (3) through (5) again.

7. Upon completion of re-assembly step 1 rotate the impeller by hand from the suction the suction inlet and check that it rotates smoothly without touching the suction cover before operating the pump.

Please obtain o-rings, packing, shaft seals and other parts from pump dealer.
