Applying Accurate System Sizing Through Quality Tank Truck Services

For fleet managers and equipment supervisors, proper sizing affects everything from the efficiency of hydraulic wet kits to the longevity of truck components. This guide covers the main factors to consider when choosing the right tank truck system, including gallons per minute (GPM), pressure (PSI), application requirements, and specific truck details.

Understanding Gallons Per Minute (GPM) and Pressure (PSI)

The first step in sizing a tank truck system is to understand the needs for gallons per minute (GPM) and pounds per square inch (PSI) for your specific application. GPM refers to the flow rate of hydraulic fluid necessary for your system, while PSI measures the pressure the system requires to operate effectively.

Gallons Per Minute (GPM): The right GPM is crucial to system efficiency. If the flow rate is too low, your system will struggle to perform, while an excessively high GPM can increase wear on components.
Pressure (PSI): PSI requirements vary widely depending on the application. High-pressure needs are common in end-dump applications, while other setups may require lower PSI.

Application-Specific Tank Truck Service Requirements

Each type of tank truck system has unique demands, which can affect everything from needing an oil cooler to including specific control valves.

End Dump Systems

End dumps typically require high-pressure systems that can handle substantial loads, making PSI and GPM crucial considerations. In these cases, it may also be necessary to install relief valves to prevent system damage during peak operations.

Remote Mount Pumps and Accessories

Consider the PSI and GPM needed to reach distant locations effectively if your setup includes remote-mounted pumps. Remote applications might also require auxiliary components, like additional hoses or connection points.

Specialized Trailers

Certain trailers require highly specific PSI and GPM settings to operate properly. Before installing a tank truck system, obtain the trailer’s requirements to make sure it aligns with your system’s output.

Combination Systems

When handling multiple applications, it’s critical to size your system to accommodate varied needs. Combination setups might require additional equipment, like an oil cooler or control valves, to protect the system from excessive wear.

4 Key Components for Sizing a Wet Kit System

The size and configuration of a wet kit should align with the specific demands of your application. Here’s what to consider when sizing your kit:

Tank Size: The hydraulic tank’s capacity determines how much fluid the system can store, which impacts the hydraulic flow rate and pressure stability. Choosing the right tank size prevents overheating and allows consistent flow.
Control Valves: Control valves manage fluid flow, allowing you to operate multiple applications with one hydraulic system. If your application requires frequent adjustments in pressure or flow rate, control valves are necessary to maintain optimal performance.
Relief Valves: Relief valves protect the system from over-pressurization, which can lead to component failure. When selecting a relief valve, ensure it matches the maximum PSI requirements for your application.
Oil Cooler: For applications that generate high heat, such as heavy-duty end dumps, an oil cooler helps maintain system integrity by dissipating excess heat. Including an oil cooler extends the life of your system and minimizes the risk of overheating.

The Importance of Transmission and Tank Truck Service Specifications

To correctly size your tank truck system, you’ll need detailed information about your truck, particularly the transmission model number, truck model and year, and desired engine RPMs.

Transmission Model Number: The transmission model impacts the system’s compatibility and performance. Selecting components that match your transmission model number allows for smooth operation.
Truck Model and Year: Different truck models and years come with unique configurations and specifications. Knowing this information helps you select compatible equipment for your truck’s setup.
Engine RPMs: The desired engine RPM affects the efficiency of your hydraulic system. Systems designed for specific RPM ranges will operate more effectively, leading to better performance and reduced wear on components.

Calculating Tank Truck System Requirements Based on Application

Once you’ve gathered the necessary data, calculating your system requirements becomes straightforward. You can determine which components, tank size, and additional equipment are necessary using the GPM, PSI, and application details. Here’s an example breakdown of common system calculations:

Determine Total GPM Needs: Review the GPM requirements for each application and add them together if running a combination setup. This gives a baseline flow rate needed for optimal performance.
Adjust for PSI Requirements: Calculate the maximum PSI needed for each application. If one application requires a higher PSI, set your relief valve and oil cooler specifications to handle that pressure.
Include Additional Components Based on Application: An end-dump application would likely need a higher PSI relief valve and an oil cooler to manage the additional heat generated.

Final Tank Truck Service Considerations for Cost Efficiency and Safety

Properly sized tank truck systems save on maintenance costs, reduce downtime, and improve safety. An improperly sized system can lead to excessive fuel consumption, shortened component life, and increased risk of hydraulic failure, all of which can be costly and dangerous.

Cost Efficiency: Systems that run at optimal GPM and PSI are more fuel-efficient and put less strain on truck engines, reducing maintenance costs and fuel expenses over time.
Safety: An improperly sized system risks over-pressurization, overheating, and fluid leaks, all of which can lead to dangerous situations on the road. Ensuring your system is correctly sized protects your team and equipment.
