Quantitative grease filling device, a pneumatic high-pressure plunger pump, pressure plate with easy to absorb high viscosity material, air pressure lift, thus more quantitative grease filling equipment, pneumatic high pressure plunger pump, pressure plate with easy to absorb high viscosity material, air pressure lift, so as to better to complete the work of conveying and injection of fluid.Design special booster lifting mechanism and fluid pressure plate.The oil pressure tray has the force of forced extrusion, and concentrates the fluid material around the valve at high pressure to help the pump absorb, which is better for the fluid medium with high viscosity.The machine is equipped with pneumatic high pressure fluid conveying pump, can be used for putty, glue, adhesive, grease, printing ink and other pipeline centralized supply and a large number of occasions.
