ABOUT WEAR AND CORROSION RESISTANCE
• The impellers, which are subject to the greatest possibility ofwear, are of tough high chrome cast iron about 20 times aswear resistant as ordinary cast iron.
• The casing, which is subject to less possibility of wear, is ofless expensive low chrome cast iron with three to five timesthe wear resistance of ordinary cast iron.
TWO-PHASE STAINLESS STEEL
18-8 system stainless steel now widely favored as an anticorrosive material is vulnerable to an atmosphere with chlorine ions. Tocope with this, EBARA has developed two-phase stainless steel which is resistant to stress corrosion cracks, for use especially inchemical plants, ocean development equipment and food industrial plants.
Two-phase stainless steel is composed of austenite with a 40 to60% ferrite content. The principle features of the superior corrosionresistance of austenite and the hardness and strength of ferrite-have been skillfully combined. This two-phase stainless steel canbe used without the problems of conventional steel such as wear,corrosion, and cracking and is especially suited for use with seawater.

Installing a self-priming tank, if your SAL pump is used for vertical, upward suction, it will be possible for you to use the pump forthe following applications:
1. Install where a general-purpose pump with foot valve is beingused. There are many cases of problems arising with a footvalve pump because the valve does not operate correctly, breaksdown or causes wear of the pump body.
2. Install where a self-priming pump is being used. There are manycases of problems arising due to inefficiency caused by thelength of time it takes for priming, malfunction of the check valveon the suction side and wear of the pump body.
3. Install where a submersible pump is being used. There are manycases of problems arising from frequent breakdown of themechanical seal due to dirt and sand, and extreme wear of thepump body.
4. Install where a vertical shaft pump is being used. There are manycases of problems arising from wear of the submersible verticalshaft bearing, and the frequent necessity of inspection for repair.
• Principles of Self-Priming: Pumping bymeans of siphon action
Once the pipes are filled with water (a varietyof methods can be used to do this) pumpingwill be sustained naturally. When the waterin a section of piping beings drop, a vacuumis created at the upper end of the pipe. Theatmospheric pressure on the surface of thewater in the water tank forces water in thetank up into the pipe so that it is once againfull of water. (In a vacuum, atmosphericpressure has enough power to push waterup 10 meters.) This is why pumping issustained when the pipe are full.If the pipethat is in the water tank is punctured, air willenter through the hole making siphoningimpossible and forcing pumping to stop.
• How to Use the Self-Priming Tank1 Open the air release valve (a) and the feed
water valve (b) and fill the tank with water.2 After the tank has been filled to the point
where water overflows from the top of thesuction pipe, close valve (a) and (b) andstart the pump.
3. As the water in the tank is sucked up bythe pump, its level will gradually drop andthe pressure level in the tank will alsodrop. However, once pressure hasdropped to a certain point, the samesiphon principle operates. The water inthe water tank on the suction side ispushed by a atmospheric pressure intothe tank.
4 Therefore, when a pump isoperated with a self-primingtank there is no need for afoot valve. When the liquidpump contains slurry, the footvalve seat is often worn to thepoint where it no longerfunction and it becomesimpossible to operate thepump. With an EBARA Self-Priming Tank, however, thissort of trouble will never arise.
5 Even when the pump is stopped, all waterin the tank will not drain which means it ispossible to start the next pump operationwithout any preparation. Note, however,that if the tank is punctured or suctionpiping is damaged, self-priming will nolonger be possible and the pump will notbe able to function.
Notes on Installation• One self-priming tank should be installed for each pump.• Pump suction piping:
1. Connect self-priming tank and pump with no more than two meters of straight piping.Avoid to use elbow as much as possible.
2. Never allow air in the suction side since pressure will drop.• Pump discharge piping:
1. Discharge piping should be higher than top of tank.2. Total discharge piping length should be as shown in table below.
3. The end of the discharge piping should be higher than suction water level.
4. Do not use a check valve. Install so that there will not be a reverse flow at the end of the discharge piping.
5. When a pump is not operating for extended periods, or when it is a type that does not use external feedwater,add water to the tank occasionally.

Dry operationIf the pump is operated empty, the bearingswill seize and be damaged due to insufficientlubrication, resulting in damage to the entirepump. After connecting the motor, alwaysprime the pump when checking the directionof rotation before starting it up.
Slurry, crystallizationSlurry contamination liquids or crystallizingliquids will cause abnormal wear to thebearings and dramatically shorten the lifeof the pump.
Operating water levelWhen the pump is being used as adrain pump, or when the liquid is beingdrained from the inside of the tank, usethe level switch to stop the pump, andcheck the suction side water level toprevent dry operation.
Adhesive liquidsLiquids which adhere to the inner surfaceof the pump, such as calcium carbonate,zinc phosphate, and non-electrolytic plating,will cause insufficient lubrication to thebearings and operation lock.
CavitationThe occurrence of cavitation causes axialvibration in the rotor, resulting in damage tothe pump.
Precaution for Use• This list is based on corrosion resistant data from material manufacturers. Corrosion due to hydraulic friction is not taken into consideration.• The basis for these decisions is made by considering only corrosion resistance. The specific gravity, viscosity and vapor pressure of the liquidsare not taken into consideration. • Examinations of capacity, total head, shaft power, and suction head due to specific gravity, viscosity, and vaporpressure should be considered separately. Crystallization and adhesion to the pump interior due to the properties of the liquid should also beconsidered separately.
