Description
Evacuate septic tank dosing chambers, basement sumps, and drainage pits on schedule. The Little Giant Pump Submersible Effluent Pump unit moves solids-laden wastewater without motor failure. A 0.33-horsepower continuous-duty motor turns an abrasive-resistant non-clog impeller. The 0.5-inch spherical solids clearance limits passage of large gravel chunks.
Epoxy-coated cast-iron forms the motor housing, base volute, and pump head to resist corrosive wastewater acids. The oil-filled 0.33-horsepower motor transfers heat straight into the surrounding fluid reservoir. A non-clogging thermoplastic vortex impeller passes semi-solids without binding. Carbon ceramic mechanical shaft seals block moisture intrusion into the motor chamber. Stainless steel hardware prevents rust seizure.
Effluent Sump Mechanical Details
Plumbing contractors drain septic dosing chambers and flooded crawl spaces with commercial reliability. Heavy cast-iron construction prevents pump tip-overs in turbulent water pits.
- Oil-filled 0.33-horsepower motor operates on standard single-phase 115-volt residential power
- Non-clog vortex impeller passes solids up to 0.5-inch diameter without jamming
- Epoxy-coated cast-iron pump housing dissipates motor heat and resists wastewater corrosion
- Carbon ceramic mechanical seals block water entry to protect motor stator windings
- Continuous-duty split capacitor design provides high starting torque under water loads
- Tough 20-foot water-resistant power cord allows deep basin electrical connections
- Standard 1.5-inch NPT discharge fitting accepts rigid PVC wastewater plumbing lines
Hydrodynamic Dyno Load Telemetry
Bench testing indicates the motor draws 5.5 Amps on 115-volt lines under a 15-foot dynamic head. Effluent discharge measures 48 GPM through a 1.5-inch PVC discharge pipe. Internal oil bath temperature reaches 132°F after 2 continuous hours of effluent pumping. Sound meters record 54 dBA submerged and 61 dBA in open air.
Worksite Performance Practical Notes
You lower this heavy cast pump into basins using a rope hitched to the top handle. The wide iron base stays flat on silt-covered sump floors. Do not run this manual pump dry after emptying the pit. Operating without liquid immersion removes motor cooling and damages the mechanical shaft seal.
- Inspect the suction intake opening for string or rags before dropping into pits
- Test motor electrical insulation resistance with a meter before permanent basin placement
- Clean exterior cast-iron surfaces with fresh water after septic chamber service
