1. Specification

• Rational design, Smaller, lighter, and easy move
• Simple operation, easy maintenance
• Low power consumption, large slurry discharge, impulse free, work pressure is stable
• Save materials, energy saving, cost-effective

2. BGJ50/30-4 piston grouting machine

BGJ50/30-4 piston grouting machine was driven the crankshaft rotational by mechanical transmission. By connecting rod make the piston do reciprocating motion, So that the mortar will through the suction valve and the pump cylinder, and then discharge by the air chamber. The machine has vent slurry valve, pressure safety valves and other safety systems.

The machine as transport mortar and pressure grouting was widely used in highways, bridges, municipal, building, tunnels, ports, dams, subways, underground and other building products industry.

It feature are small size, light weight, low power consumption, large slurry discharge, impulse free; work pressure is stable and smooth operation, saving material and energy, easy transportation.
