GH-H series dual cylinders and single action hydraulic grouting pump is suitable for grouting plugging project of high pressure and large displacement. This pump transmits pressure signals by working medium (slurry and hydraulic oil) to form closed-loop automatic control function, therefore the pump is simple in structure, can regulate timely and accurately, and has no overpressure problem.  

GH-H series dual cylinders and single action hydraulic grouting pump can grout simple-liquid, and chemical grout. 

suitable for grouting plugging project of high pressure and large displacement
simple in structure, can regulate timely and accurately
has no overpressure problem
can adjust its output and working pressure by continuously Variable adjustment
