Little Giant WGP-95-PW Dual Discharge Submersible Pump
Features include a unique dual discharge design allowing simultaneous operation of two water features. Both discharges measure 1.25 inches FNPT, with a cap and 1.25-inch 90° barbed elbow included. It is a high-pressure oil-free direct-drive pump suitable for pond filtration, waterfalls, streams, fountains, and water features up to 2400 gallons. The unit can be oriented vertically or horizontally to fit most vaults, and it ships with a 16-foot power cord for flexible placement.
Little Giant 115V 750 GPH 3-MD-SC Non-Submersible Pump
Though described for non-submersible use, this model is included for comparison of materials and design approaches. It features a leak-proof, seal-less magnetic drive with glass-filled polypropylene components designed for semi-corrosive chemicals. It is easy to install and maintain, with adjustable pump heads and wing nuts for quick servicing without tools.
Little Giant 6EC-CIA-SFS Submersible Sump Pump (20-Ft Cord)
Built to last with epoxy-coated cast iron housing and a nitrile/carbon/ceramic shaft seal, this model features a continuous-duty motor (115-volt, 5 Amp, 600-Watt PSC) and a snap-action float switch. It includes a 20-foot power cord and is designed for reliable automatic operation—turning on at 8 to 11 inches of water and off at 2 to 5 inches. It is suitable for sump or effluent applications where water levels vary.
Little Giant 6EC-CIA-SFS Submersible Pump (10-Ft Cord)
This variant shares the same core design as the 20-foot version, including cast iron construction, automatic float switch, and a 10-foot cord. It provides dependable sump and effluent performance with straightforward maintenance and a robust build for long-term use.
Red Lion RLSP33PED 115V Submersible Pedestal Pump
Designed for residential sump pits with a robust polypropylene construction for rust resistance and clog resistance. The adjustable snap-action float switch activates at 8 to 10 inches and shuts off at 3 to 5 inches. While often used for standard sump tasks, its submersible pedestal design makes it suitable for quiet operation in tight spaces with reliable automatic control.
Little Giant 230V Submersible Magnetic Drive Pump for Semi-Corrosive Chemicals
Designed for transferring or recirculating semi-corrosive chemicals and solutions, this model uses a seal-less magnetic drive with glass-filled polypropylene components and a ceramic shaft for chemical compatibility. It is easily maintained with rotatable pumping heads and wing nuts for tool-free servicing, matching the broader category of compact, reliable submersible pumps.
SEAFLO 12V 750 GPH Submersible Bilge Pump
Equipped with a built-in magnetic float switch, this 12V pump activates automatically when water rises and deactivates as the bilge clears. It emphasizes energy efficiency, drawing power only when needed. Its compact form factor and 3/4-inch outlet make it suitable for small-scale water features or emergency drainage in boats and other tight spaces.
Buying Guide: Key Considerations For 600 LPH Submersible Pumps
- Flow rate vs. head: Ensure the pump’s liters-per-hour rating aligns with your water feature’s height rise (head) and the total dynamic head of the system. A higher head reduces actual flow at the outlet, so consider both flow and lift capabilities.
- Discharge size and configuration: Dual discharge options are useful for powering two features simultaneously, such as a waterfall and a stream. Check FNPT sizing and compatibility with fittings and elbows.
- Submersible vs. pedestal designs: Submersible pumps are fully immersed and generally quieter, while pedestal models may offer easier service access. Choose based on space and maintenance preferences.
- Material and chemical resistance: For ponds with fertilizers or treated water, look for corrosion-resistant housings and seals. Cast iron housings are durable; plastic variants save weight but may be less rigid.
- Electrical safety and cord length: Verify the cord length matches your installation distance from outlets or power sources. In aquatic environments, ensure proper grounding and weather-rated connections.
- Automatic operation and float switches: A reliable float switch reduces manual monitoring by turning the pump on at low water and off as water drops. Confirm switch sensitivity and travel range.
- Maintenance and part availability: Pumps with accessible impellers, seals, and cartridge bearings simplify servicing. Spare parts should be readily available to extend product life.
- Energy efficiency: PSC motors and efficient impeller designs reduce running costs over time. Assess power draw relative to expected flow to avoid waste.
- Use-case compatibility: Submersible pumps vary from pond circulation to sump and bilge tasks. Match the pump’s intended role with your project to avoid over- or under-achievement.
When selecting a 600 LPH electric submersible pump, consider how you will use the unit, the environment, and how easy it is to maintain. The models listed above provide a spectrum of capabilities—from dual-discharge water features to automatic sump operation—helping you tailor a solution to your specific pond, fountain, or water feature project.
