CAN/CSA C820-02 (R2012)


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

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.
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.
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.
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.
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
