3. Definitions

For the purposes of this Practice, the following definitions apply:

best efficiency point (BEP): Point or capacity at which a pump achieves its highest efficiency

cartridge mechanical seal: A mechanical seal unit, including sleeve, gland, primary seals,and secondary seals, that can be tested as a unit and installed as a unit

critical speed: Speed corresponding to a lateral natural frequency of a rotor

design: Term used to define various parameters, e.g., design power, design pressure, designtemperature, or design speed

drive train components: Items of equipment, e.g., motor, gear, turbine, engine, fluid drive,clutch, used in series to drive the pump

maximum allowable temperature: Maximum continuous temperature for which theequipment has been designed when handling the specified liquid at the specified pressure

maximum allowable working pressure (MAWP): Maximum continuous pressure for whichthe equipment has been designed when the equipment is operating at the maximum allowabletemperature

maximum continuous speed (in revolutions per minute): Speed at least equal to 105% of thehighest speed required by any of the specified operating conditions

maximum discharge pressure: Maximum suction pressure plus the maximum differentialpressure that the pump is able to develop when operating with the maximum impellerdiameter at maximum continuous speed and maximum specified relative density (specificgravity)

maximum suction pressure: Highest suction pressure to which the pump is subjected duringoperation

minimum continuous stable flow: Lowest flow at which the pump can operate withoutexceeding the vibration limits imposed by this Practice

net positive suction head (NPSH): Total absolute suction head, in meters (feet) of liquid,determined at the suction nozzle and referred to the datum elevation, minus the vaporpressure of the liquid, in meters (feet) absolute. Datum elevation is top of the foundation.

net positive suction head available (NPSHA): NPSH determined by purchaser for thepumping system with the liquid at the rated flow and normal pumping temperature

net positive suction head required (NPSHR): NPSH determined by supplier testing withwater. NPSHR is measured at the suction flange and corrected to the top of the foundation.



NPSHR is the minimum NPSH at rated capacity required to prevent a head drop of more than3% (first-stage head in multistage pumps) caused by cavitation within the pump.

normal wear parts: Parts normally restored or replaced at each pump overhaul. Typicallythese are wear rings, interstage bushings, balancing devices, throat bushings, seal faces,bearings, and all gaskets.

operating region: Portion of a pump’s hydraulic coverage over which a pump operates

operating region - acceptable: Portion of a pump’s hydraulic coverage over which a pump isallowed to operate, determined by upper vibration limit specified in this Practice bytemperature rise or by other limitation specified by the supplier

operating region - preferred: Portion of a pump’s hydraulic coverage over which a pump’svibration is within the base limit specified in this Practice

owner: The party who owns the facility wherein the vertical centrifugal pumps for waterservice will be used

pressure casing: Composite of all stationary pressure-containing parts of a pump, includingall nozzles, seal glands, and other attached parts, but excluding the stationary and rotatingmembers of mechanical seals

purchaser: The party who awards the contract to the supplier. The purchaser may be theowner or the owner’s authorized agent.

rated operating point: Point at which the suppler certifies that pump performance is withinthe tolerances specified in this Practice

relative density: Ratio of the liquid’s density to that of water at 4°C (39.2°F)

rotor: Assembly of all the rotating parts of a centrifugal pump excluding the seals andbearings. If purchased as a spare, a rotor typically does not include the pump half couplinghub.

specific gravity (SG): Ratio of the liquid’s density to that of water at 4°C (39.2°F)

suction specific speed: An index of pump suction operating characteristics determined at theBEP with the maximum diameter impeller. Suction specific speed is an indicator of theNPSHR (defined in the following equation) for given values of capacity and rotating speedand provides an assessment of the pump’s susceptibility to internal recirculation. Suctionspecific speed is calculated by the following equation:



nqs = N(Q)0.5/(NPSHR)0.75

where:nqs = suction specific speed

N = rotating speed in revolutions per minuteQ = flow per impeller eye, in cubic meters per second (gallons per

minute) at the BEP with the maximum diameter impeller= total flow for single suction impellers= one-half total flow for double suction impellers

NPSHR = net positive suction head required in meters (feet) at the BEP forthe maximum diameter impeller

Note: Suction specific speed derived using cubic meters per second and metersmultiplied by a factor of 51.6 is equal to suction specific speed derived using U.S.gallons per minute and feet. The usual symbol for suction specific speed in U.S.units is Nss.

below 100°C (212°F). At a temperature above 100°C (212°F) water may become aggressive andunstable, requiring special material class based on water chemistry. Class A-1 is the lowest cost class,while class A-2 offers extended life for increased initial cost.

2. Cooling tower water is assumed to be recirculating. Build-up or concentration of chlorides and othercontaminants is anticipated, especially if temperature exceeds approximately 93°C (200°F). Class A-3shall be considered for longer service life if sulfur compounds or free chlorine is present.

3. Condensate is assumed to be at a temperature below 100°C (212°F). At a temperature above 100°C(212°F), corrosiveness of water may vary widely, and material class shall be based on water stability, pH,dissolved solids, and other water chemistry parameters.



4. Treated water is assumed to be noncorrosive, i.e., treated to control scaling, pH, and fouling (use ofbiocide or other additions). Caution shall be exercised in water chemistry control to avoid excessiveamounts of free chlorine.

5. Demineralized water is assumed to be low in chlorides and should be considered corrosive. Classes C-1and C-2 are based on considerations of minimizing corrosion and maintaining water purity. Class C-1 is acost-effective alternative, whereas C-2 may be readily available and offered as pump vendor standard.

6. Seawater is assumed to be fully oxygenated, free-flowing, clean seawater; i.e., seawater does not containhydrocarbons and is not brackish bay water with excessively high chlorides and other contaminants.Seawater outside this definition requires special materials recommendations. Additionally, if flow rate isless than 1 m/s (3 ft/s) or is frequently stagnant, pitting may occur, and special material recommendationsare required.

7. Foul water, water draw, and reflux streams vary widely in corrosivity. Class B-1 or more corrosion-resistant classes may be required. Special material recommendations shall be obtained on the basis ofexpected contaminants.

8. Produced water is corrosive and defined as seawater (or similar high-chloride water from an aquifer) thathas been injected into an oil field and subsequently risen to the surface as an oil-water mixture fromwhich water is removed and reinjected. Typical produced water is assumed to have H2S, possibly CO2, aminimum pH of 6.0, and maximum chlorides of 60,000 ppm. Class C-3 is normally a minimum, but classshall be based on purchaser-furnished water chemistry, temperature, and other parameters defined bypurchaser and supplier. Classes C-4 or C-5 may be required. Material temperature limits depend onspecific corrosive conditions.

9. Injection water is water injected into an oil-bearing formation to maintain formation pressure and enhanceoil recovery. Corrosiveness of injection water may vary widely because the water may be seawater,produced water, freshwater, or aquifer water with varying corrosivity. Typical injection water is high inchlorides and may contain H2S and CO2. Class C-3 is normally a minimum, but class shall be based onpurchaser-furnished water chemistry, temperature, and other parameters defined by purchaser andsupplier. Classes C-4 or C-5 may be required. Material temperature limits depend on specific corrosiveconditions.

10.Formation water is similar to produced water and is considered a highly saline water (brine). Formationwater comes from aquifers and other sources. Typically, formation water has high concentration ofchlorides (150,000 ppm or higher), possibly H2S, and nearly neutral pH. Material class shall be based onpurchaser-furnished water chemistry, temperature, and other parameters defined by purchaser andsupplier. Classes C-4, C-5, or other special materials beyond the scope of this Practice may be required.Material temperature limits depend on specific corrosive conditions.

Notes:(1) Mating wear surfaces of hardenable materials shall have a difference in Brinell hardness numbers (BHN) of at

least 50 BHN, unless both wear surfaces have BHN of 400 or higher.(2) Requirement for hard-facing and specific hard-facing material may be specified by the purchaser on data

sheets. Method of hard-facing application may also be specified by purchaser, or both material and method ofapplication may be specified by mutual agreement between purchaser and supplier. Alternatives to hard-facingmay include opening of running clearances and/or use of nongalling materials.

(3) Duplex (austenitic-ferritic) stainless steels are typically identified by trade name and have slightly varyingcomposition and corrosion-resistant properties. One of the most common wrought duplex steels (UNS 31803)has a nominal composition of 22% chromium, 5.5% nickel, 3% molybdenum, and 0.14% nitrogen.



(4) Super duplex stainless steels are distinguished from standard duplex steels (Note 3) by their increasedamounts of chromium (25% nominal) and other alloys, typically nickel, molybdenum, and nitrogen. They aremost frequently designated by trade name with slightly varying compositions and specific corrosion resistance.

(5) 6-Moly (super austenitic) stainless steels are enhanced austenitic stainless steels that have maximumresistance to pitting and crevice corrosion. These steels are typically required for the most severe services withhigh chloride concentrations. These steels are designated by trade name. Choice of a specific steel shall bebased on purchaser preference, mutual agreement between purchaser and supplier, and/or specific corrosiveconditions.

(6) Seal and vent piping shall be compatible with metallurgy of pump components. For classes A-1, A-2, and A-3,pipe shall conform to ASTM A106 Gr. B, and fittings shall conform to ASTM A105. For classes B-1, C-1, C-2,C-3, C-4, and C-5, pipe and fittings shall be made of an appropriate stainless steel for the corrosivity of thesystem.

(7) Wetted fasteners shall be compatible with the pump metallurgy and corrosivity of the pumped water. Somematerials, especially austenitic stainless steels, are prone to galling. Precautions are required to avoid thisproblem.

(8) Meehanite is an acceptable alternate for cast iron.(9) Fluted synthetic cutless rubber or Thordon (or equivalent) shall be used in abrasive service.
