Energy Efficiency Test Methods for Small Pumps Edition: 1
Canadian Standards Association / National Standard of Canada / 05-Apr-2002 / 14 pages

1.1
This standard applies to centrifugal pumps that require a driver-rated output of 373 W (1/2 hp) nominal up to and including 7.46 kW (10 hp) nominal.
1.2
This Standard specifies the method for testing centrifugal pumps to determine the following characteristics:
(a) the total head produced by the pump versus the pump rate of flow;
(b) input power versus pump rate of flow; and
(c) efficiency versus pump rate of flow.
1.3
This Standard does not apply to centrifugal pumps for the following services:
(a) decorative fountain pumps;
(b) fire pumps as defined in NFPA Standard 20;
(c) hydromassage pumps as defined and installed in accordance with CSA Standard C22.2 No. 218.2;
(d) jet pumps;
(e) multi-stage pumps;
(f) recreational vehicle pumps;
(g) seal-less pumps;
(h) solids-handling pumps;
(i) sprinkler pumps for residential lawn watering applications;
(j) deep well submersible pumps;
(k) submersible-type effluent pumps up to and including 1.49 kW (2 hp);
(l) submersible-and column-type sump pumps for residential applications; and
(m) utility or contractor pumps.
1.4
This Standard does not cover the measurement of motor efficiency, nor does it specify the minimum efficiency required of the motor used to drive a pump, whether the motor is a separate motor coupled to the pump or is mounted on a common shaft with the pump.
Note: For motor efficiency measurements, refer to CSA Standards C390 and CAN/CSA-C747.
1.5
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
