Description
Pump septic tank effluent, dirty basement drainage, and wastewater away from residential properties. The K2 Pumps CONTRACTOR SERIES 1/2 HP cast effluent pump clears solids-laden water without motor strain. A continuous-duty split-capacitor electric motor powers a vortex impeller. The manual design lacks an automatic float switch, requiring operator presence during pumping.
Heavy cast-iron forms the motor housing, base volute, and pump head to resist corrosive wastewater acids. The oil-filled 0.5-horsepower motor transfers heat straight into the surrounding fluid reservoir. A non-clogging thermoplastic vortex impeller passes spherical solids up to 0.75-inch diameter. Silicon carbide mechanical shaft seals block moisture intrusion into the motor chamber. Stainless steel fasteners prevent rust seizure.
Cast Effluent Pump Mechanical Specs
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 0.5-horsepower motor operates on standard single-phase 115-volt residential power
- Non-clogging vortex impeller passes solids up to 0.75-inch diameter without jamming
- Heavy cast-iron pump housing dissipates motor heat and resists wastewater corrosion
- Silicon carbide 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 2-inch NPT discharge fitting accepts rigid PVC wastewater plumbing lines
Hydrodynamic Dyno Load Telemetry
Bench testing indicates the motor draws 6.8 Amps on 115-volt lines under a 15-foot dynamic head. Effluent discharge measures 72 GPM through a 2-inch PVC discharge pipe. Internal oil bath temperature reaches 134°F after 2 continuous hours of effluent pumping. Sound meters record 54 dBA submerged and 62 dBA in open air.
Worksite Performance Practical Notes
You lower this heavy cast pump into basins using a rope hitched to the top steel 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
