The pump is the heart of any commercial pool circulation system. HuiQi manufactures 12 commercial pool pump series — variable-speed drives, high-efficiency centrifugals, seawater/stainless specialist pumps and integrated strainers — supplied to hotels, resorts and public pools in 50+ countries since 2007. This guide covers how to choose, size and specify them.

1. The pump's role in pool circulation
A pool pump moves water from the basin through filtration and disinfection and back to the pool, at a rate set by the required turnover time. Undersize it and clarity and sanitation suffer; oversize it and you waste energy. For fountain and water-feature pumps see our fountain & water-feature pump guide.
2. The 12 HuiQi commercial pool pump series
HuiQi's commercial pool pump range is grouped into four families:
| Family | Series (examples) | Typical use |
|---|---|---|
| Variable-speed (VSD) | HQ-KLBP, HQ-KAP, HQ-KUP, HQ-SCPB, HQ-ESP | Energy-saving duty; up to 90% savings vs single-speed |
| High-efficiency centrifugal | HQ-ZS (stainless horizontal single-stage), HQ-NIS, HQ-LCAP, HQ-SLP, HQ-LAKP, HQ-STP | High-flow commercial & municipal |
| Seawater / hot-spring specialist | HQ-KBP, HQ-KAP, HQ-KUP, HQ-KLBP | Corrosive water, salt, seawater, hot springs |
| Strainers (paired) | HQ hair & lint strainers | Protect impellers from debris |
Representative models: HQ-ZS stainless centrifugal, HQ-NIS high-efficiency, HQ-KLBP seawater/hot-spring, HQ-KBP seawater pump, HQ-ESP. The full set is on the pool pumps collection.
3. How to choose the right commercial pool pump
- Define flow & turnover: pool volume ÷ target turnover time → required GPM. See pool pump sizing (GPM/turnover).
- Calculate TDH: static lift + pipe/fitting friction + filter + nozzle backpressure. See TDH calculation.
- Pick the curve: choose a series whose pump curve meets GPM at TDH.
- Single vs variable speed: VSD cuts energy on low-demand cycles — compare in VSD vs single-speed.
- Motor & voltage: TEFC enclosures for plant rooms; match local voltage. See TEFC vs induction motors.
- Confirm efficiency/compliance: check WEF and U.S. DOE rules. See WEF and DOE 2025/2027.
4. Efficiency and compliance
WEF (Weighted Energy Factor) is the standardized metric to compare pumps; higher is better. For the U.S. market, DOE efficiency rules phase in through 2025 and 2027 — confirm compliant models. Variable-speed pumps are the single biggest OPEX lever for continuous-duty commercial pools.
5. Installation and service
Correct suction staging, strainer placement and commissioning determine reliability. Our contractor installation checklist walks the steps. For the full buyer's view, see commercial pool pump buyer's guide.
Frequently asked questions
How many commercial pool pump series does HuiQi make?
Twelve — spanning variable-speed drives, high-efficiency centrifugals, seawater/hot-spring specialists and paired hair/lint strainers.
Variable-speed or single-speed for a commercial pool?
For continuous-duty or variable-demand pools, variable-speed wins on energy and life. For simple constant duty, single-speed can be cheaper upfront. Cost comparison.
Which pump handles seawater or hot springs?
The HQ-KBP, HQ-KAP, HQ-KUP and HQ-KLBP series are built for corrosive media — seawater, salt and hot-spring water.
What does WEF mean for a pool pump?
Weighted Energy Factor — a standardized efficiency metric; higher WEF means less energy per unit circulated. Explained.
Do U.S.-bound pumps need DOE compliance?
Yes, through 2025/2027 phases. Confirm compliant models. Guide.
Can HuiQi size and supply internationally?
Yes — pumps are manufactured in-house and shipped matched to TDH/voltage to 50+ countries. Request a quote.
