Overview
The Electric Agitator Grout Pump is a dual-purpose construction machine engineered to mix and pump grout or mortar in demanding environments. It integrates an electric motor, agitator, and high-pressure pump, eliminating the need for separate mixing equipment. Commonly deployed in civil engineering, mining, and infrastructure projects, it enhances efficiency by reducing manual handling and ensuring material consistency. Modern variants emphasize portability, corrosion-resistant components, and user-friendly controls. Brands like Putzmeister and Sany offer models tailored for small-scale repairs or large industrial applications. Its versatility makes it indispensable for tasks requiring precise material placement, such as soil stabilization or crack injection.
Structure and Working Principle
The machine comprises three core subsystems: the electric motor, mixing chamber, and piston/diaphragm pump. The motor drives both the agitator (typically a helical blade) and the pump mechanism. As materials are fed into the hopper, the agitator blends them uniformly, while the pump draws the mixture and delivers it through hoses at adjustable pressures. Key structural elements include wear-resistant seals, hardened steel pistons, and anti-clogging filters. Advanced models feature variable speed controls to regulate output viscosity. The closed-loop design minimizes waste and airborne dust, complying with worksite safety standards.
Key Features
1. **Integrated Agitator**: Ensures consistent material homogeneity, critical for bonding strength. 2. **Adjustable Pressure**: Ranges from 0.5–5 MPa to accommodate diverse applications like fissure grouting or curtain wall construction. 3. **Portability**: Compact units weigh under 100 kg, often with wheeled frames for mobility. 4. **Durability**: Abrasion-resistant coatings extend the lifespan of wetted parts. Additional features may include digital pressure gauges, quick-disconnect hoses, and overload protection. These attributes reduce downtime and improve operational precision.
Application Areas
Primary applications include: - **Tunneling**: Injecting grout to stabilize loose rock formations. - **Foundation Work**: Filling voids under structures or compensating for soil settlement. - **Concrete Repair**: Sealing cracks in bridges or dams with epoxy grouts. Secondary uses cover geothermal drilling (backfilling boreholes) and precast concrete manufacturing. The pump’s ability to handle additives like accelerators or fibers expands its utility in specialized projects.
Maintenance and Precautions
Regular maintenance includes inspecting seals, lubricating moving parts, and flushing the system with water after each use to prevent curing residue buildup. Avoid pumping materials exceeding the recommended particle size (typically <3 mm) to prevent blockages. Operators should wear PPE (gloves, goggles) when handling chemicals. Store the pump in a dry environment to avoid motor corrosion. Scheduled servicing of electrical components is advised to ensure safety compliance.
B2B Procurement Guide
When sourcing, evaluate: 1. **Capacity**: Match output (e.g., 10–30 L/min) to project scale. 2. **Material Compatibility**: Verify chemical resistance for acidic/alkaline grouts. 3. **After-Sales**: Prioritize suppliers offering spare parts and on-site training. Leasing options are viable for short-term projects. Request performance certifications (e.g., CE, ISO) to guarantee reliability. Bulk purchases may attract discounts of 5–15% for orders exceeding 10 units.
