Ultra-High Pressure Hand/Air Pumps TLTAL alloy space material. Light weight,Website: , high strength, corrosion resistant and impact protected are suitable for a variety of aggressive environments. With two speeds, an automatic change-over valve switches with precision from low to high pressure smoothly. During low pressure, a greater flow is provided to save the operating time to increase work efficiencies. Built-in safety valve provides safe dual protection. We design it as per the particular space on customer’s machine.
