What are crocodile water pumps?

Crocodile water pumps, often referred to by many as pig-head pumps, are centrifugal pumps notable for their strong suction and efficient high-lift water delivery. Thanks to their characteristic pump head design, these water pumps can steadily transport water from deep wells, ponds, lakes, or underground water sources.

Currently, crocodile water pumps are widely applied in domestic water supply, irrigation, livestock farming, construction projects, and water treatment systems. The advantages of this pump line include durable operation and reliable performance in water environments containing light sediment or thin sludge while maintaining operational efficiency.

Structure of crocodile water pumps

Crocodile water pumps are highly rated for durability thanks to their sturdy structure and the use of materials with good load-bearing capacity during operation.

• Pump housing: Usually cast from solid cast iron, featuring high hardness, good impact resistance, and corrosion limitation to effectively protect internal components.
• Water pump motor: The motor is typically wound with copper wire, supporting good electrical conductivity and heat dissipation to help the machine operate stably, durably, and save more electricity over a long period.
• Impeller: Made of cast iron or steel, optimally designed to create strong centrifugal force, supporting a fast and stable water suction and discharge process.
• Pump shaft: Uses high-hardness alloy steel, offering good wear resistance and ensuring stable power transmission between the motor and the impeller.
• Suction and discharge ports: Designed according to standard dimensions, convenient for installation and connection with various popular piping types available today.

Operating principle of crocodile water pumps

Crocodile water pumps operate on the principle of centrifugal force. When the pump motor operates, the pump shaft will rotate, driving the impeller to move at high speed.

Under the effect of centrifugal force, water is pushed outward from the center of the impeller, simultaneously creating a low-pressure zone in the middle to draw water from the source into the pump chamber. Afterward, water continues to be discharged outward through the discharge port with stable pressure, making the pumping process continuous and efficient.

Classification of crocodile water pumps

1-phase crocodile water pumps: These are crocodile water pumps using a single-phase power supply (typically 220V), suitable for residential or small-scale applications.

Crocodile water pumps under 3.7kW: Including crocodile water pumps with a capacity of less than 3.7kW, typically used for moderate pumping needs.

Crocodile water pumps under 50m3/h: Referring to crocodile water pumps capable of pumping a water flow of less than 50 cubic meters per hour, suitable for applications that do not require large flow rates.

Notes when purchasing crocodile water pumps

• Choose the right capacity and usage needs: It is necessary to determine the water discharge head, water flow rate, and actual purpose to choose a machine with a suitable capacity, avoiding weak pumping or excessive power consumption.
• Check motor quality and materials: Priority should be given to motor lines wound with copper wire, thick cast iron housing, and stainless steel shafts to ensure stable operation, low heat generation, and high durability during long-term use.
• Note the water source: If used for pumping water with light sediment or thin sludge, a suitable pump line must be chosen to limit clogging and increase the lifespan of the impeller.
• Prioritize reputable suppliers: Products with clear technical specifications, full warranty policies, and good technical support should be chosen for convenience during installation and use.
