The 4JLT series features a drive cylinder diameter of 250mm. As an ultra-high flow pressure booster pump, the 4JLT series is developed based on the 2JLT series by enlarging the original 160mm drive cylinder to 250mm. This enhancement doubles the capacity of the high-pressure cylinder and doubles the output flow while maintaining the same pressure ratio. The 4JLT series is also a dual-drive, double-ended air-driven hydraulic pump, characterized by high output pressure, energy-free pressure maintenance, automatic fluid suction, automatic pressure holding, automatic pressure replenishment, and suitability for various media. The product comes with a one-year warranty.
