Pool Main Pump Motor
The main pool pump motor at the facility (as of August 2021) is a Leeson Model C254T17DK13A (catalog #199987.00). It is rated for 15 HP (11 kW), 37 FLA @ 230 VAC. It is inverter duty rated (confirmed by the local manufacturer's rep) with a 10:1 PWM ratio (60 Hz, 1770 RPM down to 6 Hz, 177 RPM).
It has a month/year manufacturing designation of "H2016" - presumably corresponding with August (H=8) 2016. This makes sense, as the pump was noted to have been replaced in early 2017.
== Power Factor Correction Capacitor (PFCC)
At present (as of August 2021), no power factor correction capacitor (PFCC) is in use. It was decided that given cost priorities, a PFCC would not offer sufficient payback to justify its purchase.
Myron Zucker was contacted in August 2020 and provided two options, both rated for 240 VAC, 5 kVAr, 3-phase, 60 Hz:
- KNM23005-3 (NEMA 12 for indoor use, 14" H x 9.25" W x 5.25" D)
- KNM23005-3N3 (NEMA 3R suitable for outdoor use, 16" H x 12" W x 6" D)
Applying a 5 kVAr PFCC would reduce the FLA from 37 A to 31 A. This would reduce i-squared-R losses by 6 A. Actual losses are then based upon the cable run.
Variable Frequency Drive (VFD)
IMPORTANT: At this time, this section is for investigation purposes only. It has not been determined when/if a VFD will be implemented.
