Key Features of HCP FNK-33U Submersible Pump
Vortex Impeller
The vortex impeller creates a whirlpool effect that allows long, fibrous materials and solid waste to pass through without direct contact, significantly reducing the risk of clogging in this vortex impeller sewage pump.
Dual Mechanical Seals
This dual mechanical seal pump for septic tank emptying features a superior abrasion-resistant design with carbon/ceramic and silicon carbide seals, housed in an oil-filled chamber to ensure maximum durability and leak prevention.
Auto-Cut Protector
An automatic thermal protector is built into the motor to prevent burnout from high temperatures or excessive amperage, enhancing the reliability of this 3HP submersible pump for factory wastewater systems.
Epoxy Cable Base
A waterproof epoxy resin seal at the cable entry point prevents moisture from wicking into the motor, protecting the internal components and ensuring long-term operational integrity.
High-Efficiency Dry Motor
All stator coils are treated with an insulating varnish, providing excellent insulation, high efficiency, and the durability needed for demanding industrial wastewater pump applications.
Performance Overview
The HCP FNK-33U 3HP sewage pump is designed for continuous duty, delivering consistent performance in challenging conditions. Its performance curve shows a maximum flow of 212 GPM at a 7-foot head and a maximum head of 61 feet at 18 GPM, making it suitable for applications requiring both significant lift and high-volume transfer. The pump operates effectively in liquid temperatures up to 40°C (104°F).
Applications
Building, hotel, and industrial factory sewage drainage
Emptying of septic tanks, cesspits, and sewage pump stations
Drainage of flooded basements and garages
Pumping for sprinkler systems
Surface water dewatering
Effluent drainage solutions for commercial facilities
Use as a heavy-duty sump pump in large-scale applications
