Each product page provides details on voltage, cord length, and automatic features to fit typical American installations.
Little Giant WGP-95-PW Dual Discharge Pump
The Little Giant WGP-95-PW provides a dual discharge design, enabling two water features to operate simultaneously. Both discharges are 1.25-inch FNPT, and the kit includes a cap and a 1.25-inch 90° barbed elbow. This 115-volt, oil-free direct-drive pump is ideal for pond filtration, waterfalls, streams, and other water features up to 2400 gallons. Its versatility allows vertical or horizontal installation to suit various vaults or fountains, and it ships with a 16-foot cord for flexible placement.
Little Giant 6MD-SC Non-Submersible Pump for Semi-Corrosive Chemicals
This non-submersible magnetic-drive pump is designed for transferring or recirculating semi-corrosive chemicals. It features a leak-proof seal-less drive, glass-filled polypropylene construction for the volute and magnet housing, and a ceramic shaft with high-purity alumina thrust washers for chemical resistance. Installation is straightforward, with rotatable pumping heads and wing nuts for easy cleaning and service without special tools.
Little Giant 6EC-CIA-SFS 1/3 HP Submersible Sump Pump (10 ft Cord)
Engineered for continuous duty, the Little Giant 6EC-CIA-SFS uses an energy-efficient 115-volt PSC motor with an automatic snap-action float switch. The cast iron housing provides durability, while the polypropylene base resists corrosion. A 20-foot cord offers flexible placement. The unit is designed to start at water levels around 8 to 11 inches and shut off around 2 to 5 inches, making it suitable for residential sump pits and effluent applications with steady performance.
Little Giant 6EC-CIA-SFS (10 ft Cord) Submersible Pump
Another variant of the Little Giant automatic sump pump line, this version emphasizes reliable operation with a 10-foot cord. Built to last through continuous use, it features a cast iron composite housing, seal design with a nitrile/carbon/ceramic mechanical shaft seal, and smooth maintenance. The automatic operation is controlled by a snap-action float switch, activating at about 8 to 11 inches of water and turning off between 2 and 5 inches.
Little Giant WGP-80-PW Dual Discharge Submersible Pump
The WGP-80-PW mirrors the dual discharge concept for powering two features with one pump. It is designed for pond filtration, waterfalls, streams, and fountains up to large volumes. The dual 1.25-inch FNPT outlets, along with a 16-foot cord, offer flexible installation, and the unit can be oriented vertically or horizontally to fit most waterfall vaults or fountains. This ensures efficient water flow while maintaining simplicity in setup and maintenance.
Buying Guide
- Flow vs. head: Consider the required flow rate (GPH) and the head height of your water features. Higher GPH is useful for ponds and waterfalls, while lower head heights prioritize lift efficiency.
- Submersible vs. pedestal: Submersible pumps save space and reduce noise, but pedestal pumps are easier to service and may offer greater robustness in certain basins.
- Discharge options: Dual discharge designs enable powering multiple features from a single unit. Check FNPT sizing (commonly 1.25 inches) and compatible fittings.
- Automatic operation: Float switches provide hands-off control, turning on at higher water levels and off when water recedes. Ensure the float switch range matches your basin’s water cycle.
- Material and chemical resistance: For channels and chemical bowls, consider pumps with corrosion-resistant housings and seals (e.g., polypropylene, cast iron with protective coatings).
- Cord length and voltage: Ensure the supply matches your electrical setup (typically 115 V in the US) and check cord length for safe routing and accessibility.
- Maintenance and serviceability: Look for pumps with rotating heads, easy access screws, and minimal tools required for cleaning or seal replacement.
- Durability and warranty: Cast iron or reinforced housings offer longevity in demanding environments; verify warranty terms for long-term reliability.
- Noise and vibration: Some models feature quiet operation due to magnetic drives and proper mounting; evaluate location where pump noise matters.
These considerations help compare options across pond, sump, and bilge pumping needs. When selecting, map features like dual discharge capabilities, continuous duty ratings, and automatic switch behavior to your specific installation to optimize performance and maintenance intervals.
