The double-cylinder high-pressure cement grouting pump is a hydraulic reciprocating piston pump designed for medium-pressure, high-flow-rate injection of cement grout, bentonite, and similar media. It is widely used in construction, mining, and underground engineering for foundation reinforcement, waterproofing, and basic treatment.



Working principle of the double cylinder cement grouting pump:
It is a double-acting, double-cylinder reciprocating pump driven by an electric motor and a hydraulic system.
The electric motor drives a gear pump to generate hydraulic pressure.
An electro-hydraulic directional valve controls the reciprocating motion of the two cylinders.
One cylinder discharges grout (grout discharge), while the other cylinder draws in new grout (grout intake).
The alternating motion of the two cylinders achieves continuous, pulsation-free flow under high pressure.



Double cylinder high pressure cement grouting pump features:
High Pressure, High Flow: Working pressure up to 5MPa, flow rate 7.2m³/h.
Dual-Liquid Injection Capability: Can inject two different media simultaneously or separately.
Hydraulic Drive: Smooth operation, low noise, and convenient pressure/flow adjustment.
Robust and Compact: All-steel construction, small footprint, easy to move and maintain.
Wide Material Compatibility: Handles cement slurry, mud, bentonite, and chemical grouts with particle sizes ≤5mm.



Applications of cement grouting pump:
Tunneling and Mining: Water plugging, rock mass reinforcement, and lining repair.
Foundation Engineering: High-pressure jet grouting, compensating grouting, and foundation reinforcement.
Hydraulic Engineering: Dam and reservoir seepage control and reinforcement.
