• Capacity: Choosing the right capacity depends on the application. Smaller tanks are suitable for dust control on small construction sites, whereas larger tanks are needed for firefighting or large-scale irrigation.
• Baffles: These internal structures within the tank minimize water sloshing during transport, improving stability and handling. Imagine trying to drive with a giant, wobbly water balloon on your back – baffles prevent that!
• Coatings: Internal coatings can protect the tank from corrosion and ensure water quality, especially for potable water transport.

Pumps: Delivering the Water Where It’s Needed

The pump is like the heart of the water truck’s delivery system. It’s responsible for moving water from the tank to the spray nozzles, hoses, or other discharge points. There are different kinds of pumps, each with its own strengths. Centrifugal pumps are the most common, known for their high flow rates and ability to handle various water sources. Positive displacement pumps, on the other hand, are excellent for delivering precise volumes of water, making them ideal for applications like agricultural spraying.

Pump Features to Consider:

• Flow Rate (GPM – Gallons Per Minute): This determines how quickly the pump can move water. Higher GPM is crucial for tasks like firefighting.
• Pressure (PSI – Pounds per Square Inch): The force with which the water is delivered. Higher PSI is needed for tasks like power washing or reaching high areas.
• Power Source: Pumps can be driven by the truck’s engine (PTO – Power Take-Off), a separate gasoline or diesel engine, or even an electric motor.
• Impeller Material:The impeller is the rotating part that moves the water. Consider bronze, stainless steel and cast iron, materials are chosen based on durability and resistance to wear and tear.
