HCP AN-22 Submersible Dewatering Pump: 2 HP, 2-inch, 132 GPM, 80.4 ft Head

HCP AN-22 Submersible Dewatering Pump for Silty Water and Flood Control

Product Overview

The HCP AN-22 submersible dewatering pump is a 2-inch unit built for muddy, silty and gritty water. This 2 HP submersible dewatering pump moves up to 132 GPM and lifts to 80.4 ft on an open cast-iron impeller, and it can sit as deep as 66 ft (20 m) below the surface, double the 33 ft rating of HCP's smaller AN pumps. Common installs are construction sumps, basements, utility vaults, and fishponds.

Available in 240V single-phase or 575V three-phase, and certified to cUL and CSA for Canadian installations.

Key Features of the HCP AN-22 Submersible Dewatering Pump

• Open cast-iron impeller (FC200). Moves more water per horsepower than a vortex design. Passes solids to 3/8 inch.
• 66 ft (20 m) submersion rating. Double HCP's smaller AN pumps.
• Double silicon carbide mechanical seals in an oil bath.
• Motor protection, 240V model: auto-cut thermal protector and moisture sensor. The 575V model has none built in and needs overload protection in the control panel.
• Epoxy resin cable base. Blocks moisture from wicking into the motor through the core wires.
• 2-pole dry motor. 3440 rpm, Class F insulation.
• cUL and CSA C22.2 No. 108-14 certified.

HCP AN-22 Submersible Dewatering Pump Specifications

240V or 575V: which AN-22 do you need?

Both models are the same 2 HP pump with identical hydraulics: 132 GPM, 80.4 ft of head, 3/8 inch solids, open cast-iron impeller. The difference is the motor and how it is protected.

What's Included

• HCP AN-22 submersible dewatering pump
• 30 ft power cable
• Convertible discharge outlet (flange and elbow compatible)

Key Benefits of the 2 HP Submersible Dewatering Pump

• Reaches deep excavations, shafts and sumps that a 33 ft pump cannot be set low enough to clear.
• Keeps running in sandy, gritty water instead of wearing the impeller out.
• Meets Canadian certification requirements out of the box, with no field evaluation before an inspector signs off.
• Two voltage options on the same 2 HP submersible dewatering pump: 240V single-phase for standard sites, 575V three-phase for commercial power.
• Holds flow at height better than a vortex pump of the same horsepower, so it clears long or steep discharge runs.

Performance Overview

The HCP AN-22 dewatering pump moves up to 132 GPM and lifts to 80.4 ft, with a standard duty point of 66 GPM at 59.1 ft. Flow falls as head rises, so size this 2 HP submersible dewatering pump to the vertical lift from the water to your discharge point.

Applications

The HCP AN-22 dewatering pump suits jobs where the water is dirty, deep, or both:

• Construction site and excavation dewatering
• Deep sumps and shafts (up to 66 ft submersion)
• Basement sump pits and cellar drainage
• Emergency flood control
• Manhole and utility vault dewatering
• Fishpond and water feature drainage
• Light commercial and industrial drainage on three-phase power

Setup and Usage Guidelines

• The 240V model requires a 240V single-phase connection. Verify breaker compatibility before installation.
• Check phase rotation on the 575V model before running it. A DOL three-phase motor turns backwards on reversed phases and will not pump.
• Ensure the sump pit allows space for the float switch to operate without obstruction.
• Do not use for heavy sewage or large trash. This pump is intended for clean to muddy water with small solids (max 3/8 inch).
• Vertical installation is standard. Set the pump on a stable, level surface.
• The pump may be submerged to 66 ft (20 m). Do not exceed that depth.

Accessories and Add-Ons

• Pair with a 30 ft piggyback wide-angle float switch for automatic operation.
• 90-degree elbow flange outlet or guide rail system (GRS) for easier removal and service.
• Run the 2-inch discharge into a 2 inch layflat discharge hose to carry water clear of the work area.
