MG-20

The Koken MG-20 is a precision grouting attachment engineered for foundation engineering and underground construction projects requiring reliable, high-pressure material injection. Weighing 645kg, this pump delivers consistent performance across soil stabilization, micropile grouting, and void-filling operations. The Koken MG-20 specifications include a maximum operating pressure of 20 MPa with a flow capacity of 20 liters per minute, accommodating diverse slurry formulations from cementitious compounds to specialized chemical grouts. Built for demanding subsurface applications, this attachment combines compact geometry with industrial-grade pressure regulation, enabling seamless integration with existing drilling and foundation systems. The user-interface controls provide real-time adjustment capability, allowing field teams to fine-tune delivery rates and pressures to match specific soil conditions and material characteristics without equipment reconfiguration. The Koken MG-20 attachment excels in foundation underpinning, ground anchoring, tunnel stabilization, and dewatering support—applications where controlled injection pressure and flow precision directly impact structural performance and project timelines. Its proven durability in demanding subsurface environments makes it a dependable choice for contractors managing complex geotechnical challenges.
