Water-based fluid for hydraulic supports and pump stations in coal mines
MFD-40 is a water-containing low-temperature hydraulic fluid developed for hydraulic supports and pump stations in coal mines operating in cold conditions. It provides low-temperature fluidity, rust protection, corrosion control, lubrication, and compatibility with suitable seal materials. Bulk supply, large-volume procurement, OEM, and export cooperation are available.
MFD-40 is a water-containing low-temperature hydraulic fluid manufactured using antifreeze components, lubricating components, rust inhibitors, and corrosion inhibitors. It is designed for mine hydraulic supports, hydraulic support pump stations, and related mining hydraulic equipment operating in cold conditions.
The fluid provides low-temperature fluidity, rust protection, corrosion control, lubrication, and compatibility with suitable hydraulic sealing materials. Proper fluid selection, system cleanliness, and equipment compatibility must be confirmed in accordance with the hydraulic support manufacturer's requirements and the intended operating temperature.
