Th is standard provides minimum requirements for horizontal centrifugal
pumps and for vertical line-shaft pumps for installation in wells, water treatment
plants, water transmission systems, and water distribution systems.
1.1.1 Service. Pumps described in this standard are intended for pumping
fresh water having a pH range between 5.5 and 10.0, a temperature range from
33°F to 125°F (14°C to 37°C), a maximum chloride content of 250 mg/L, and a
maximum suspended solids content of 1,000 mg/L, and which is either potable or
will be treated to become potable.
1.1.2 Pumps covered by this standard.
1.1.2.1 Driver power range: 10 hp to 1,500 hp (7 kW to 1,100 kW).
1.1.2.2 Rate of fl ow (at BEP): 100 gpm to 40,000 gpm (23 m3/hr to 9,100
m3/hr).
1.1.2.3 Maximum discharge pressure ratings. Th e maximum steady-state
pressure at the pump discharge (which considers the suction pressure, possible operation
for short periods at shutoff head, and the elevation of the discharge) is limited to the pressure rating for the ANSI/AWWA C207 class of fl ange shown for
the pump types described below.
1. For horizontal pumps:
–Discharge 42 in. (1,067 mm) and larger: Class E (275 psig,
1,900 kPa).
–Discharge smaller than 42 in.: Class F (300 psig, 2,100 kPa).
2. For vertical line-shaft pumps: Class F (300 psig, 2,100 kPa).
1.1.2.4 Maximum steady-state suction pressure ratings.
1. For horizontal pumps: 50 psig (340 kPa).
2. For vertical line-shaft pumps: 100 psig (700 kPa).
1.1.3 Pump types included in this standard.
1.1.3.1 Horizontal pumps. Refer to Hydraulic Institute (HI) Standard
ANSI/HI 1.1–1.2 for a description of types:
1. Separately coupled, single-stage, inline, fl exible coupling.
2. Separately coupled, single-stage, inline, rigid coupling.
3. Separately coupled, single-stage, end suction.
4. Separately coupled, single-stage, horizontal, axial or mixed fl ow.
5. Single-stage, horizontal, double- or single-suction split case.
6. Vertically mounted, horizontal, double- or single-suction split case.
1.1.3.2 Vertical pumps. Refer to ANSI/HI 2.1–2.2 for a description of types:
1. Barrel (can) pump with suction nozzle in discharge head or in
barrel.
2. Deep well.
3. Wet pit with above- or below-fl oor discharge.
1.1.4 Drivers. This standard does not include drivers.
1.1.5 Conditions not covered by this standard.
1. Conditions resulting from water hammer, cavitation, and hydraulic
pulsations.
2. Excessive installed operating noise and vibrations, which may require
special design, construction, and installation.
