HCP FN-23U 3 HP Submersible Effluent Pump – 2" Discharge, 240V

Heavy-Duty Submersible Pump for Low-Pressure Sewer Systems and Dewatering

Product Overview

The HCP FN-23U is a 3 HP submersible pump for wastewater transfer and sewage applications. Its cast iron and stainless steel construction ensures reliability for residential and light commercial dewatering. With a vortex impeller, this pump effectively handles solids without clogging. Cleanflow supplies the HCP FN-23U for septic tank drainage and low-pressure sewer systems.

Key Benefits of the HCP FN-23U Effluent Pump

• Lifts water up to 75 feet, making it ideal for deep system applications.
• Prevents clogging in low-pressure sewer pump stations by passing solids up to 1-3/8 inches in diameter.
• Features a built-in auto-cut thermal protector to prevent motor burnout from overheating or high amperage.
• Provides a long operational life with a double mechanical seal system housed in a food-grade oil chamber.
• Resists corrosion with an epoxy resin-sealed cable base and stainless steel motor frame.
• Adapts to various installations with a standard 2-inch NPT vertical discharge connection.
• Reduces maintenance with an abrasion-resistant silicon carbide lower seal for harsh environments.

Key Features of HCP FN-23U Effluent Pumps

Vortex Impeller Design

The U-Type vortex impeller creates a whirlpool effect that allows fibrous materials and solids to pass through the pump without directly contacting the vanes, significantly reducing the risk of jamming in wastewater applications.

Auto-Cut Motor Protector

This internal switch automatically shuts down the pump if it senses excessive heat or amperage draw, preventing catastrophic motor failure and extending motor service life during overload conditions.

Double Mechanical Seals

Located in an oil-filled chamber, the dual seal system (Carbon/Ceramic upper, Silicon Carbide/Silicon Carbide lower) provides superior resistance to abrasion and ensures the motor remains isolated from the pumped liquid.

Epoxy Cable Base

The cable entry point is sealed with hardened epoxy resin to prevent moisture from wicking into the motor through the core wires, a common failure point in standard submersible pumps.

High-Efficiency Dry Motor

The air-filled, dry-type motor is highly efficient and housed in a stainless steel shell, providing excellent heat dissipation even during extended duty cycles in a dewatering pump system.

Performance Overview

The HCP submersible pump 2 inch discharge model FN-23U is engineered for high-head applications, maintaining flow against significant back pressure. This pump is suited for higher head wastewater applications where maintaining flow against back pressure is required. Flow output decreases as lift increases, consistent with vortex impeller performance. It is rated for continuous duty when fully submerged within standard wastewater temperature ranges.

Applications

• Low-pressure sewer systems
• Septic tank effluent drainage
• Commercial wastewater transfer
• Basement dewatering and sump pits
• Industrial process water removal
• Agricultural irrigation and drainage
• Emergency wastewater management

Installation & Use Notes

• Check Rotation: For 3-phase models, always verify impeller rotation is counter-clockwise when viewed from the bottom before full installation.
• Thermal Protection: Single-phase models include built-in thermal protection; three-phase units require external overload protection via a control panel.
• Submersion: The pump relies on the surrounding liquid for cooling; avoid running dry for extended periods.
• Discharge Piping: Use a check valve in the discharge line to prevent backflow and water hammer.
• Solids Limitation: While capable of handling 1-3/8" solids, this unit is not a grinder pump; avoid flushing sanitary items like wipes or plastic.

Accessories & Add-Ons

• Layflat Discharge Hose: Pair with a 2" hose for temporary dewatering applications.
• Guide Rail System (GRS): Compatible with HCP guide rail systems for easy lift-out maintenance in deep wet wells.
• Check Valve: Essential for vertical lifts to protect the pump mechanics.
