A manual cement grouting pump is a device that delivers and injects cement-based grouting materials manually, without the need for electricity. It is suitable for small-scale, low-pressure, or power-constrained structural reinforcement, crack repair, and waterproofing projects.
 
Manual cement grouting pumps generate pressure through manual operation (such as hand cranking, foot pedaling, or lever principles), requiring no external power source. This makes them suitable for construction sites without a power supply or with limited space (such as tunnels and basements). Most manual cement injection pumps use a diaphragm or piston structure, using the reciprocating motion of a rubber diaphragm or piston to draw in and discharge grouting materials.
 
The pressure and flow rate of a manual cement grouting pump are typically adjusted by the operating force, offering high precision and making it suitable for scenarios requiring fine control (such as crack grouting). Manual cement grouting pumps can output flow rates up to 10 liters per minute, with a vertical delivery distance of 6 meters and a horizontal delivery distance of 15 meters, meeting the needs of small-scale repairs.
 
The manual grouting pump has a wide range of uses and can be used to inject various low-viscosity and good-flowing slurries, such as pure cement slurry and chemical slurry.
 
1. Building Structure Reinforcement: Used for repairing concrete cracks, filling hollow metal parts, and fixing machine bases. For example, in bridge maintenance, a manual cement grouting pump can inject epoxy resin or cement-based grouting materials into cracks to restore structural strength.
2. Underground Engineering Waterproofing: In damp environments such as tunnels and basements, a manual cement grout pump can inject chemical grouting materials (such as polyurethane) or cement-based waterproofing materials to seal seepage channels. Due to its high pressure and small volume, it is often used for grouting reinforcement behind tunnel linings.
3. Power-Constrained Scenarios: In situations without power or at temporary construction sites, a manual grouting pump can replace an electric pump for grouting operations. For example, in field bridge inspections, a manual grout pump can quickly repair cracks found during inspection without the need for a generator.
4. Fine Repair and Decoration Engineering: Suitable for small-area operations such as sealing door and window frames and repairing hollow tiles.
