When it comes to keeping your dump trailer operating smoothly and efficiently, selecting the best hydraulic fluid for dump trailer is crucial. Hydraulic fluids play a vital role in transferring power within your trailer’s hydraulic system, but not all fluids are created equal. To understand why, we need to dive into three key properties of hydraulic fluids: viscosity, anti-wear, and non-foaming.

Viscosity

Think of viscosity like the thickness of a liquid. Water is thin; it has low viscosity. Honey is thick, so it has high viscosity. For hydraulic fluids, getting the viscosity right is essential because it affects how easily the fluid can flow through the system. If it’s too thick (high viscosity), it won’t flow well, especially in cold weather. If it’s too thin (low viscosity), it might not provide enough lubrication.

Anti-Wear

Your dump trailer works hard, and its hydraulic system has many moving parts. Over time, these parts can wear down, leading to breakdowns and costly repairs. That’s where anti-wear properties come in. The best hydraulic fluids for dump trailers contain additives that form a protective layer on metal surfaces, reducing wear and extending the life of your equipment.

Non-Foaming

When hydraulic fluid moves quickly or gets agitated, it can start to foam. This is bad news because foam can lead to inefficient hydraulic system operations and even damage. Non-foaming hydraulic fluids contain special additives that prevent foam from forming, ensuring your dump trailer operates smoothly.
