The XPB series high-pressure grouting pump is a conventional, general-purpose pump. It offers moderate pressure, a compact design, and affordable pricing, making it a cost-effective option with high performance. The hydraulic end of this product adopts a split-type combined pump head design for easy disassembly. The power end uses rolling-bearing transmission, offering low noise, reduced temperature rise, and extended sealing service life up to 60%, ensuring reliable 24-hour continuous operation.

This high-pressure pump is suitable for high-pressure jet grouting for ground treatment, curtain grouting, retaining cofferdams, mine leakage plugging, shaft lining protection, slope anchoring, and other application fields. In addition, it has obtained a national patent.
