Liberty 280-Series Submersible Pump – Heavy-Duty Performance for Demanding Applications
Engineered for efficiency in low-head to mid-range pumping scenarios, the Liberty 280-Series submersible pump delivers unmatched reliability for septic tank effluent (STEP) systems, mound system installations, liquid waste management, and high-capacity sump duties. With a robust 1/2 horsepower motor and a 37-foot shut-off head, this pump excels in moving fluids over moderate elevations while handling solids up to 3/4 inch in diameter—ideal for environments where debris or particulate matter is common.
The 280-Series stands out with its durable one-piece cast iron “UniBody” housing, which minimizes leaks and simplifies maintenance. Its stainless steel rotor shaft and fasteners resist corrosion for extended lifespan in harsh conditions. A permanently lubricated upper and lower bearing system ensures smooth operation without frequent servicing. The wide-angle float switch allows precise control over pump activation levels, while the oil-filled motor with hermetic sealing provides thermal overload protection against overheating or electrical surges.
Designed with user convenience in mind, this model includes a quick-disconnect power cord (available in 10′ or 25′ lengths) for easy installation and removal. The removable stainless steel bottom screen facilitates cleaning and prevents clogging from large particles. Operating on 115V power supply, it balances energy efficiency with high output to meet commercial and residential demands alike.
Key Features:
– 37-foot shut-off head for reliable fluid transfer in varied terrains
– 3/4-inch solids handling to tackle tough debris without clogging
