Collection: Water Pumps

Head Height Changes Everything

Pump flow ratings are measured at zero head. Add four feet of lift, a few elbows and some pipe run, and real output can land well under half the box figure. Size for the flow you need at your head height, and plan on roughly five to ten times display volume per hour through the sump.

Types Stocked

• AC pumps — single speed, mechanically simple, few points of failure.
• DC controllable pumps — adjustable speed with a controller and feed-mode ramping.
• Nano and internal pumps — small units for compact returns, reactors and skimmers.
• Utility and external pumps — high-flow options for big systems, transfers and water changes.

Heavier pumps ship at actual freight cost. A larger pump throttled back usually runs quieter and cooler than a small one at full tilt. Questions on sizing? Email info@jlaquatics.com.
