Little Giant 502103 Small Submersible Pump 300 Gph

Product Description

The LITTLE GIANT 502103 is a compact, oil-filled submersible pump designed for continuous liquid transfer and recirculation across a wide range of commercial, industrial, and residential applications. Rated at 300 GPH at 1 foot of head, it operates fully submersed and features an epoxy-coated cast aluminum housing for durability in wet environments. The 1/4-inch MNPT discharge outlet accepts 1/2-inch I.D. tubing, making it straightforward to plumb into existing setups. A thermally protected motor and snap-off screened inlet round out the core design. Licensed HVAC and mechanical contractors, as well as experienced DIYers, install this pump in statuary, fountains, water displays, and machine tool coolant systems.

The 502103 is suited for statuary fountains, decorative water displays, air conditioner condensate or water-feature applications, machine tool coolant recirculation, and similar tasks where compact size and reliable flow are required. Its hooded inlet design makes it particularly well matched to statuary installations where debris management is a priority. The pump operates on standard 115-volt single-phase power and ships with a 6-foot cord, allowing direct connection in most residential and light commercial settings without extension wiring.

Installation Notes

Installation should be performed by a qualified plumber or mechanical contractor in accordance with applicable local codes. Always disconnect power at the circuit before handling the pump or making plumbing connections. Confirm the discharge tubing inner diameter matches the 1/2-inch I.D. specification before connecting to avoid flow restriction. The snap-off inlet screen should be cleaned regularly to maintain rated flow performance.
