HCP AN-21A Submersible Dewatering Pump for Muddy Jobsite Water
Product Overview
The HCP AN-21A submersible dewatering pump is a 1 HP, 120V unit that moves up to 88 GPM, reaches 53 ft of head, and passes 1/4 inch solids. Its vortex impeller pulls muddy and silty water from sump pits, basements, and construction excavations. The pump comes in single-phase and three-phase versions.

- Discharge: 2 inch (50 mm), Female NPT
- Max Flow: 88 GPM
- Max Head: 53 ft
- Solids Handling: 1/4 inch (7 mm)
- Impeller: Vortex
- Cord: 30 ft, 3-prong 120V plug
Key Features of HCP AN-21A Submersible Dewatering Pumps
- The vortex impeller passes 1/4 inch (7 mm) solids, so the AN-21A moves muddy, silty, and sandy water that clogs a standard sump pump.
- At 1 HP the AN-21A reaches 53 ft of head, clearing deeper pits and longer discharge runs than a 1/2 HP pump.
- A cast-iron (FC200) casing and volute with a 304 stainless steel motor frame withstand abrasive, continuous duty.
- A double mechanical seal (carbon/ceramic upper, silicon carbide lower) runs in an oil-filled chamber to keep water out of the motor.
- The 120V model adds a built-in thermal protector and moisture sensor, and the IP68 sealed motor runs fully submerged to 33 ft (10 m).

Performance Overview
The 1 HP motor reaches about 53 ft of head, so the AN-21A holds flow on higher and longer discharge runs that stall a smaller pump. Flow peaks near zero lift and drops as height rises.
Applications
- Dewatering flooded basements and cellars
- Emptying construction and excavation pits with silty runoff
- Sump-pit and utility-vault drainage on jobsites
- Flood control and storm cleanup
- Higher-head jobs where a 1/2 HP pump stalls, such as deep pits and long hose runs

Frequently Asked Questions
Does the HCP AN-21A replace the A-21?
Yes. It is HCP's direct replacement for the discontinued A-21, with the same 1 HP, 2 inch, 1/4 inch solids setup and an updated AN-series motor. It comes in 120V, 240V, and 575V, so existing A-21 installs swap over with no plumbing change.
How much water does the AN-21A move?
Up to 88 GPM, with a maximum head near 53 ft. Flow is highest at low lift and drops as discharge height rises, and the 1 HP motor holds flow at height better than a 1/2 HP pump.
AN-2.5 or AN-21A, which do I need?
Choose the 1/2 HP AN-2.5 for light dewatering at low lift, and the 1 HP AN-21A when you need more flow (88 GPM) or higher head (about 53 ft) for deeper pits and longer runs. Both pass 1/4 inch solids.
What solids can the AN-21A handle?
Up to 1/4 inch (7 mm), through the vortex impeller. That covers muddy, silty, and sandy water. It is not a sewage pump; those pass 2 inch solids.
Is the HCP AN-21A certified, and does it have motor protection?
Yes. It carries CSA C22.2 No. 108-14 and cUL (UL778), with an IP68 sealed motor. The 120V model includes a built-in thermal protector and a moisture sensor.
