ZBL50-4/7.5 funnel injection pump, ZBL50-4/7.5 injection pump 
 ZBL50-4/7.5 funnel injection pump, ZBL50-4/7.5 injection pump, ZBL50-4/7.5 funnel coal injection pump, ZBL50-4/7.5 injection pump product description: ZBL-type funnel material injection pump construction of wells for mining, surface and underground water shut-off, pressure injection of high concentration of cement slurry. Grouting can also be used for coal or other non-corrosive media, pressure injection of coal mine gas drainage hole sealing and grouting. As the funnel performance and self-absorption material with a certain flexibility in the use of rubber ball, so you can note the concentration of large or with a slurry of particles. 
 ZBL50-4/7.5 funnel cutting coal injection pump, ZBL50-4/7.5 injection pump features: 
 1.ZBL funnel-type material under the injection pump 
 (1) Due to funnel material, performance self-priming pump, to inject a large concentration of the slurry. 
 (2) of the pump into the discharge plasma cutting using cutting core rubber ball, so to inject the slurry containing solid particles. 
 (3) After grouting plunger exterior surface has a certain hardness and wear resistance, good performance, long life.
