Koshin Submersible Trash Pump PKS-65011 2 Inch NPT Dewatering Utility Machine (0.5 HP 110V 4760 GPH 33ft Head 5/8 Solids Wastewater Pond Drainage)

Koshin PKS-65011 1/2 HP 110V 2" Electric Submersible Trash Dewatering Pump

The Koshin PKS-65011 1/2 HP electric submersible trash pump drains flooded commercial basements, evacuates construction excavation trenches, clears retention ponds, and pumps wastewater containing spherical solids up to 5/8 inches in diameter at high-volume delivery rates up to 4,760 GPH (80 GPM) with a 33-foot maximum discharge head. Powered by an energy-efficient 110V 7-amp motor with built-in thermal overload protection and dual oil-bathed silicon carbide mechanical seals, this compact dewatering unit operates reliably in water as shallow as 5.5 inches while supporting temporary dry-run conditions. Featuring a compact 10-inch diameter footprint that fits easily inside narrow sumps, paired with non-toxic DTE 24 paraffin seal oil and a completely rebuildable modular architecture, it equips utility crews, site contractors, and municipal maintenance specialists with heavy-duty dirty-water drainage backed by a 3-year limited manufacturer warranty.

Best Used For:

• Excavation Trench and Jobsite Pit Dewatering: Clearing muddy groundwater, rainwater pools, and gritty runoff from foundation footings and utility trenches at rates up to 4,760 gallons per hour.
• Wastewater and Pond Drainage with Solids: Transferring sludge, leaves, sand, pebbles, and wastewater containing suspended debris up to 5/8 inches in diameter without impeller clogs.
• Basement, Sump, and Pool Evacuation: Pumping standing floodwater out of residential basements, parking garages, and swimming pools down to a 5.5-inch operating depth.

Key Performance & Safety Features

• High-Capacity 5/8-Inch Solids Handling: Semi-vortex trash passage allows leaves, mud, small stones, and sewage solids to pass freely through the volute without jamming.
• Double Silicon Carbide Mechanical Seals: Dual shaft seals encased in an isolated lubrication chamber protect motor internals and provide dry-run resilience against abrasive grit.
• Thermal Motor Overload Protection: Automatic thermal shut-off sensor prevents stator burnout caused by low-voltage drops, accidental dry-running, or locked rotor conditions.
• Shallow 5.5-Inch Water Level Operation: Efficient intake geometry allows the pump to prime and operate continuously in standing water depths down to 5.5 inches.
• Environmentally Safe DTE 24 Paraffin Oil: Food-grade non-toxic light paraffin lubricant ensures environmental safety in retention ponds, agricultural basins, and aquatic applications.
• Completely Field-Rebuildable Design: Modular pump casing and replacement wear components allow easy maintenance and extended equipment service life.

Technical Specifications

Pro-Tip: When pumping muddy excavation pits containing coarse aggregate or gravel, place the pump inside a perforated 5-gallon bucket or atop a concrete masonry block; this maintains unobstructed flow through the 5/8-inch solids passage while preventing large bedrock fragments from blocking the bottom strainer.
