1-Phase Submersible Pumps are water pumps (water pump motors) designed to be submerged in liquid and are usually preferred for residential applications and small systems due to their convenience and easy connection to household power supplies. This type of submersible pump (also known as a submersible water pump) operates on a single-phase power supply (typically 220V).

Key features of 1-Phase Submersible Pumps
- Uses a 1-Phase 220V power supply: The unit operates on the 220V power supply popular in Vietnam, eliminating the need for a 3-phase electrical system. This makes it easy for users to operate at home, on farms, in shops, or in civil construction projects.
- Fully submersible design: The motor is enclosed in a sealed pump body with excellent water resistance, ensuring stable operation when fully immersed in water. The surrounding water also acts as a motor coolant, helping to increase equipment longevity.
- High pumping efficiency: The pump is capable of continuous water pumping with a stable flow rate, well meeting water supply, drainage, or irrigation needs. Many models are designed with diverse heads and flow rates to suit each specific application.
- Energy saving: Thanks to the high-efficiency motor and optimized design, the 1-Phase Submersible Pump consumes reasonable electric power, helping to reduce operating costs during long-term use.
- High durability: The pump body is typically made of stainless steel, cast iron, or corrosion-resistant alloys, allowing it to withstand humid environments and extend service life. Many products are also equipped with high-quality mechanical seals to minimize water leakage into the motor.

Applications of 1-Phase Submersible Pumps
- Draining domestic wastewater from manholes and basements: Used to discharge wastewater and rainwater from manholes, basements, or low-lying areas in buildings. The pump helps handle water quickly, keeping spaces dry and minimizing flooding.
- Pumping water from boreholes and dug wells for households: Applied in extracting groundwater for daily domestic use. The equipment provides a stable water source for bathing, washing, and cooking.
- Irrigation and fish pond water supply: Suitable for watering ornamental plants, vegetables, or supplying water for household-scale fish ponds. The pump helps maintain the necessary water volume while saving energy and operating costs.
- Water supply for livestock farming: The pump is applied in livestock farms to supply water for barns, cooling systems, cleaning facilities, or pumping water into storage tanks for animals.

Frequently Asked Questions
Do 1-Phase Submersible Pumps need an additional dry-run float switch?
It is recommended to install a dry-run float switch or use a pump model with an integrated automatic float to prevent dry running, protect the motor, and extend equipment lifespan.
Should I choose a stainless steel or cast iron pump body?
Stainless steel bodies have good corrosion resistance, suitable for humid environments or clean water. Cast iron bodies offer high rigidity, good impact resistance, and are commonly used in industrial or wastewater applications.
What is the maximum installation depth of a 1-Phase Submersible Pump?
Each product has a different installation depth limit, typically ranging from a few meters to tens of meters. Users should consult the manufacturer’s technical specifications before making a selection.
