Description
High Volume Water Pump for Agricultural Irrigation and Flood Control
Product Overview
The HCP Model L-405A pump is a high-capacity submersible unit designed for low-head applications that require substantial water flow. Commonly used in agriculture, aquaculture, and flood-prone areas, this submersible dewatering pump features an axial/mixed flow impeller to optimize water movement while minimizing energy consumption. Ideal for tasks like pond circulation or drainage, the L-405A ensures efficient, rapid water transfer. Manufactured by HCP, a leading Taiwanese pump company, it delivers reliable performance even in challenging conditions.
Key Benefits of the HCP L-405A Submersible Pump
- Achieves high-capacity movement with a max flow rate of 216 GPM (49 m³/h).
- Operates efficiently on standard 120V single-phase power with a 1/2 HP motor.
- Handles water with small solids up to 3/8" (10mm) without clogging.
- Resists corrosion in diverse environments using a sacrificial anode and epoxy resin cable base.
- Connects easily to existing piping systems via a standard 4-inch discharge outlet.
- Protects internal components with double mechanical seals and an IP68 protection rating.
- Ensures motor safety during continuous operation with an auto-cut thermal protector.

Key Features of HCP Model L-405A Submersible Dewatering Pump
Axial and Mixed Flow Impeller
This impeller design allows the high-volume water pump to move large quantities of water efficiently at low heads, reducing energy consumption for large-scale transfer tasks.
Double Mechanical Seals
The pump uses a double mechanical seal system (CA/CE & SiC/SiC) housed in an oil chamber, which prevents water intrusion and extends the service life of the motor.
Corrosion-Resistant Materials
Construction includes an Aluminum Bronze (ALBC3) impeller and a sacrificial anode, offering enhanced durability against oxidation, particularly in agricultural or slightly saline water conditions.
Auto-Cut Thermal Protection
The motor includes an automatic thermal cutoff that shuts down the pump if it overheats, preventing permanent damage during heavy usage cycles.
Epoxy Resin Sealed Cable Base
The cable entry is sealed with epoxy resin to prevent moisture from wicking into the motor housing, a common failure point in submersible units.
Large 4 Inch Discharge
A 4-inch discharge water pump outlet minimizes friction loss, facilitating maximum flow rates for time-sensitive dewatering or filling operations.
Performance Overview
The HCP L-405A is characterized by high-flow, low-head performance. It excels in scenarios where moving large volumes of water quickly is more critical than lifting water to great heights. The pump maintains efficiency across its curve, delivering up to 216 GPM at lower heads. It is rated for continuous duty when submerged, making it suitable for applications like constant pond recirculation or extended flood mitigation tasks.
Applications
- Flood control pump for low-lying areas
- Aquaculture water transfer and circulation
- Agricultural irrigation pump for farms and paddies
- Pond water circulation and oxygenation
- Water supply for landscape features and waterfalls
- De-watering of cellars or basements (high volume)
- Drainage for industrial cooling systems
Common Use
- Farm Irrigation
- Fish Farm Water Management
- Landscape Water Features
Installation & Use Notes
- Requires a 120V single-phase power source capable of handling 7.8 running amps.
- The pump must be fully submerged for optimal cooling and continuous operation.
- Do not exceed the maximum head of 13 feet; flow reduces to zero at this height.
- Ensure the 4-inch discharge pipe is free of restrictions to maintain the rated GPM.
- Regularly inspect the sacrificial anode if used in corrosive water environments.
Accessories & Add-Ons
- SJE PumpMaster Plus float switch: Pair with this switch for automated on/off operation in sump or tank applications.
- Layflat Discharge Hose (4"): Ideal for temporary drainage setups.

Frequently Asked Questions
What is the best pump for muddy and silty water?
The HCP L-405A can handle water containing light silt and small solids up to 3/8 inch. It is primarily designed as a high-volume water pump. For very thick slurry or heavy mud, a dedicated slurry pump would be more appropriate.
How many gallons per minute does a 1/2 HP dewatering pump move?
The HCP Model L-405A can move up to 216 gallons per minute. This high output is achieved through its axial and mixed flow impeller design, which prioritizes volume over pressure.
Is this submersible pump suitable for pond recirculation and drainage?
Yes. The L-405A is well suited for pond recirculation and drainage due to its high flow rate, making it effective for water turnover, circulation, and oxygenation.
Is this a heavy-duty water pump for construction sites?
Yes. With its cast iron casing, aluminum bronze impeller, and double mechanical seals, the L-405A is suitable for construction site drainage where large volumes of water must be removed from shallow areas.
Can this electric submersible pump be used for flood management?
Yes. The L-405A functions effectively as a flood control pump, capable of moving more than 12,000 gallons per hour to clear flooded basements, fields, or low-lying properties.
Where can I buy industrial dewatering pumps in Canada?
Industrial dewatering pumps such as the HCP L-405A are available through Cleanflow, with shipping options across Canada and the United States.
