LGP100/150/20PI-E grout mixer pump for ground improvement is a combination of mixer, agitator and grout pump in one base frame. The high shear colloidal grout mixer volume is 100L, agitator volume is 150L. Grouting pressure and output are step-less adjustable, when high-speed: the follow 0-20L/min, pressure 0-43Bar; when low-speed: the follow is 0-10L/min, pressure is 0-100Bar.

► Application:

1. Ground improvement: tube injections, soil-mix procedures, injection screens;
2. Tunnel construction: injections for reinforcing and sealing the ground, pipe screen injections, mortar back-filling injections, cotact injections;
3. Anchorages: earth and rock anchors, floor nailing, borin anchors;
4. Ditch-free building: pipe jacking, micro-tunnelling, directional drilling;
5. Special civil engineering: slotted and narrow wall construction, pile foundations;
6. Pre-stressed concrete: injection of the cable channels.

► Features:

1. One and two-oil gear pump to get large output and high pressure in the same grout pump.
2. Single piston and two-acting, by our special design to get the same volume in both rod and no rod chamber.
3. Vertical pump with compact size.
4. Hydraulic drive, safely releasing pressure when pumping block. 
5. Ball valve.
6. Up to 5mm particle size. 
7. Low flow pressure surge system.
8. Lower charging material height for mixer.
9. High-speed colloidal grout mixer.
