Figure 10 Expansion tank

Expansion Tank- (P/N 1C16717P1)

This tank, included in a standard pump package, has an internal volume of 8.8 gal. (33 l) and a maximum pressure of 100 psi (690 kPa).

This tank is sized for a typical “open” system with a fluid volume of less than 75 gal. (280l). When used in a “closed” system, volumes of up to 140 gal. (910l) can be accommo- dated. The use of a safety relief valve, field supplied, is recommended for systems “closed” to atmospheric venting. Other piping accessories for filling, venting, or adjusting the fluid in the system, are recommended, but not included.

To Calculate Total Pump and Drycooler Full Load Amps (FLA): Total FLA = Pump FLA + Drycooler FLA

To Calculate Total Pump and Drycooler Wire Size Amps (WSA)

Total WSA = Largest Motor FLA x 1.25 + Sum of other Motor FLA values

To Calculate Total Pump and Drycooler Maximum Overcurrent Protective Device (OPD) Total OPD = Largest Motor FLA x 4.0 + Sum of other Motor FLA values
