BFK-10/1.2 coal with the sealing pump 
 Mine grouting sealing pump BFK-10/1.2 (2.4) sealing pump, BFK-10/1.2 coal mine sealing pump, BFK-12/2.4 sealing pump BFK-15/2.4 sealing pump, BFK-2.4 sealing pumps for coal mine, coal mine BFZ-10/1.2 sealing pump the BFZ-10/2.4 coal mine sealing pump, BFK10/2.4 sealing pump 
 The BFK mine sealing pump sealing device is designed various types of drilling for coal mine development, mainly used in coal mine gas drainage drilling, the sealing of the seam water injection drilling and other drilling. The BFK mine sealing pump easy to use, when used only to send the slurry pipe in the borehole to be sealed orifice of fixed and block without the need to treat seal drilling segment reaming and sent to the slurry pipe to send until the bottom of the seal drilling, simplifying the sealing process, reducing the labor intensity of the sealing operation. BFK mine sealing the pump output flow, pressure, level hole sealing length of up to 30m, vertical hole maximum sealing length of up to 20m, to meet the requirements of long distance sealing and rapid sealing. BFK mine sealing pumps, mixing, conveying high-consistency pulp, no shrinkage due to the high consistency slurry, drilling can ensure tight sealing, to improve the quality of sealing of boreholes.
