Recommendations & Warnings

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.

At any time exceeding six (6) months, but no more than twenty four (24), the equipment must be stored in a controlled area, keeping it away from contact with rain, dust, etc., and the temperature is maintained between 43-104 °F. If there is a possibility of high humidity (coastlines, etc.), the entire unit must be sprayed with antioxidant liquid.

Service Stations
To find the nearest Barmesa Pumps authorized service shop, please directly contact your distributor or the factory.

Installation
The pump should be as close as possible to the liquid to be pumped, with a minimum number of couplings, adapters, etc., in order to reduce friction on the suction side.

The suction and discharge piping must be perfectly aligned in the pump volute and supported independently using support or anchors, this to prevent excessive load on the volute.

The anchors of the motor are to be anchor, on a raised base, approximately 4″, this to prevent accumulated water from entering the motor.

**See friction table in pipes and fittings to determine the dimensions of the suction and discharge.

Suction

Use pipe or hose reinforced sufficiently robust to prevent collapsing by the difference in atmospheric pressure. Check for leaks at all joints.

A successful operation depends on the calculation of the friction loss in the suction, considering acceptable limits. The minimum suction pipe size to use can be determined by comparing the NPSH available at the pump suction against the NPSH required by the impeller, as shown in the performance curves.

Usually, we recommend using a pipe diameter of 1/2″ to 1″ greater as that of the suction volute or body.

A strainer or sieve should be installed in the suction to prevent the entry of objects. The strainer must have a free entry area at least three times the pipe diameter. Usually a suction valve is combined with a strainer Figure 1.

Figure 1 Proper installation.

Figure 2 Wrong installation.

Suction height – suction pipe should have a slope of 0.39″ per 3.3 ft of suction. Never exceed 16.4 ft suction, considering friction. (Figure 3)

Positive/Drowned Suction – A gate valve is installed in the suction pipe to service the pump (Figure 4). Volute or body have plugs, and these must be removed to allow trapped air to escape.

Figure 3 Inclination.

Correct

Incorrect

Figure 4 Positive suction.

Correct

Discharge pipe

Use pipe or hose reinforced sufficiently robust to prevent destruction due to high pressure.

Due to the cost of energy or BHP necessary to overcome the friction generated by using a smaller diameter pipe, a larger diameter discharge pipe is commonly used than the required by the volute or body.
Figure 5 Positive suction.

Incorrect
A retention valve in the suction pipe is not recommended. If required, better install the valve in the discharge pipe.

Figure 6 Discharge piping.

Correct

Incorrect

In order to determine the optimal size of the piping, compare the total cost of the equipment’s operation (cost of the pump, control equipment, piping and energy consumption). By increasing the discharge diameter reasonably, it reduces the required BHP due to the low friction. Perform different tests using several piping diameters until you find the more convenient.

The pipe, valves, etc. should be perfectly align with the volutes suction and discharge centerlines, this to avoid any excessive loads on the pumps volute. If needed, install new expansive joints to protect the pump from excessive thermal or pressure forces.

► Pre-Operation

1. Check Voltage and Phase Compare the voltage and phase information stamped on the pump name plate. –

2. Check Pump Rotation – Improper motor rotation can result in poor pump performance and can damage the motor and/or pump. Check rotation on three phase units by momentarily applying power and observe the “kickback”.
   
   Bottom of Pump
   Kickback should always be in a counter-clockwise direction as viewed from motor end or opposite to impeller rotation. Impeller rotation is counter- clockwise as viewed from bottom of pump.

3. Name Plate – Record the information from the pump name plate to drawing in front of manual for future reference.

4. Priming – Every centrifugal pump must be primed (suction pipe and pump’s body should have liquid), before operating. Install the foot valve at the suction pipe Figure 1 and fill with liquid the superior part of the pump’s body. Sometimes air is trapped inside the body, to remove it you should uncap the male plug until the liquids spills out. Re-install the male plug using a sealant. !

IMPORTANT! Do not operate pump without priming first. Operating dry will damage seal.

Starting
When starting for the first time your equipment check that the discharge valve is 90% closed. Gradually open the valve until the motor runs at full load (amperage plate). Never allow the amperage consumed by the pump exceeds the maximum permitted by the engine.

Mechanical seal
Mechanical seals installed in this pumps are lubricated by water, there for the pump should not be operated dry. You will find the appropriate seal for each use and liquid to be pumped, check with your Barmesa Pumps distributor for more information.

IMPORTANT! – Always unplug the pump before applying maintenance, service or repair to avoid electric shock.

Maintenance Body and Impeller – All pump parts are removable by removing nuts and bolts.

For body maintenance, disconnect the suction and discharge, and remove the body of the intermediate coupling.

For maintenance of the impeller is not necessary to remove the suction or discharge, simply remove the body nuts; this would uncover the impeller.

Examine and replace if it shows wear or damage. When the impeller requires replacement, remove the screw of the shaft, and using a puller, remove the impeller being careful not to abuse the keyway of the shaft. It is important not to overfill the oil tank because it would cause an increase in pressure by heating, affecting the bearings and seals. In normal operation, the frame temperature increases 122 °F above ambient temperature.

Mechanical Seal – To inspect or replace the shaft seal, remove the body and impeller. If any part shows wear or damage, replace both parts (stationary seat and rotary part). The rotating seal parts may be stuck together with the shaft, this happens when the seal has been assembled for a long time.

If the mechanical seal does not leak and there is need to open the pump for inspection or cleaning, DO NOT remove the seal, remove the spring only if the impeller needs to be removed. Once a seal has been in operation is very difficult to remove and reassembly without creating a seal leak.

Disassembly
Mechanical Seal – Perform the steps above. Remove the rotating part. It may be necessary to remove the intermediate link to remove the stationary seat. To do this, remove the nuts and washers that attach the coupling to the motor. When removing the coupling, the steady part will move towards the front seat of the shaft and the sleeve. If the seat does not yield itself, push from the rear of the coupling.

Handle seal parts with extreme care. DO NOT damage lapped surfaces.

Reassembly
_ Mechanical Seal – _Identify all parts of Figures 7 and 8. The ring (6) and seat (1) are perfectly polished, so care must be taken not to scratch or smudge. The cleaning during the assembly process is very important.

IMPORTANT! – All parts must be clean before reassembly.

Step 1: Install the intermediate coupling if it was previously removed. Make sure the shaft and cavities, where will it seats, are clean.
The shaft sleeve should not be sharp, but a radius of about 1/32″. It is recommended that lightly polish the area of the shaft. If the shaft and it radius are perfectly polished, the seal can be relatively easily installed.

Step 2: Install the seat assembly (1 and 2) on the inside of the intermediate coupling, slightly moistening with water on the rubber parts (do not use grease or oil). This assembly should be done only manually, meaning without the use of an instrument.

Step 3: Install the rotating portion of the seal without the spring. Moisten the arrow and the inside of the seal with some water (do not use grease or oil). With clean, dry hands, insert the rotating portion to the shaft, sliding it abuts the stationary seat. Once the seal is in place, insert the spring (5).

Step 4: Place the impeller and washers; tighten the hex screw.

Troubleshooting Chart

Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.

A) The pump does not prime, the vacuum gauge indicates a lower reading than normal.

| 1. Air leak in the suction system.|

• Threaded joints in the suction tightness.-  Gaskets for no wear.
• The mechanical seal for leaks.
• The drain plug has leaks.
• The vacuum gauge may be leaking.

2. Insufficient liquid in thepump casing.|

• That the pump´s body is filled with water.

3. Low operating speed.|

• The motor speed (RPM).

4. Bound pump.|

•  Impeller rotates freely.
• Internal parts are clean.

5. Mechanical defect.|

• That the internal parts are not worn.

B) The pump does not prime, the vacuum gauge reading indicates higher than normal.| 1. Pipe clogged suction.|

• The suction line is clean.

C) The pump priming good vacuum gauge reading is normal, the manometer indicates a lower pressure than normal.| 1.  The pump speed is very low.
2.  Mechanical defects.|

• The voltage is correct.
• The internal parts for wear.

a D) Th r e pump m priming good       e vacuum gauge reading isalmost normal, reading the manometer is greater.| 1. Discha s rge obstru a cted.|

• T p he discharg u e is clear of m obstructions.
•   p – That the discharge valves operate correctly.

E) The pump loses its priming during operation, vacuum gauge reading drops to zero.| 1. suction dynamic leveltoo high.|

• When the pump is operating, never lackswater in the suction.

2. The pump is sucking air.|

• For leaks in suction piping, flanges andgaskets.

• That there is no vortex effect at the end of the suction, this lack of water.

F) The pump priming pumps well and satisfactorily but noisy.

| 1. Pump base is loose.|

• That screws are tight at the base.- There are no cracks in the base.

2. Cavitation.

|

• The dynamic level is not too high
• That the pumping capacity is not too much.- The pump is operating in the range of NPSHR
• If reducing flow makes the noise gone, then the problem is in the point above; partially close the discharge valve.

3. Bearings.|

• The bearings for wear.
• That there is oil in the deposit.

4. Vibration.|

• The impeller does not have any foreign material.
• The pump is operating in the range.
• That the alignment is correct.

G) Motor overload.

| 1. Low Voltage.|

• The voltage is correct.

2. Overload.|

• The amperage of the plate is not exceeded.
• There is no foreign material that may force the impeller.
• That the motor is suitable for the pump.
