Clean water pumps

Energy Efficiency Regulations  

Regulatory definition 

Clean water pump, with or without mechanical equipment, driver and controls, that is designed for pumping clean water – other than a fire pump, a self-priming pump, a prime-assist pump, a magnet-driven pump, a pump designed to be used in a nuclear facility, a pump designed to Canadian or United States military specifications or a pump designed and marketed for use as a pool pump, that:

1. is one of the following types:
   1. an end suction close-coupled pump with a maximum specific speed of 5000 RPM,
   2. an end suction frame mounted pump with its own bearings and with a specific speed not more than 5000 RPM,
   3. an in-line pump,
   4. a radially split, multi-stage, vertical, in-line diffuser casing pump, or
   5. a submersible turbine pump with a bowl diameter not greater than 152 mm (6 in),
2. has a shaft input power not less than 0.75 kW (1 horsepower) and not greater than 150 kW (200 horsepower) at best efficiency point and full impeller diameter;
3. has a flow rate of 5.68 m3/h (25 US gallons/min) or greater at best efficiency point and full impeller diameter;
4. has a maximum head of 139.9 m (459 ft) at best efficiency point and full impeller diameter;
5. has a design temperature range that lies within -10 and 120°C (14 and 248°F); and
6. is designed to operate with either a 2-pole or 4-pole induction motor or a non-induction motor with a nominal speed of rotation of either 1800 RPM or 3600 RPM, as determined in accordance with 10 C.F.R. Appendix A, and in which the driver and impeller rotate at the same speed.

¹Equipment class designations consist of a combination (in sequential order separated by periods) of: (1) An equipment family (ESCC = end suction close-coupled, ESFM = end suction frame mounted/own bearing, IL = in-line, RSV = radially split, multi-stage, vertical, in-line diffuser casing, ST = submersible turbine; all as defined in §431.462); (2) nominal speed of rotation (1800 = 1800 rpm, 3600 = 3600 rpm); and (3) an operating mode (CL = constant load, VL = variable load).
