The LGP220/450/38H-H Hydraulically Driven Grout Station brings slurry preparation and delivery together in a compact arrangement. It provides contractors with a coordinated mixing, holding and pumping system for projects where compatible hydraulic power is available.

Inside the 220 L mixer, water, cement and suitable additives are blended through centrifugal-pump recirculation. The material passes through the circulation circuit and returns to the mixer until the batch is ready for transfer. A squeeze valve then directs the prepared slurry into the 450 L agitator.

The agitator acts as a buffer between batch mixing and grout delivery. By keeping the slurry moving, it helps limit settling while material awaits pumping. This separate holding stage also makes the mixer available to prepare another batch. The integrated hose pump delivers slurry at a specified output of 19–38 L/min, with a pump pressure specification of 14 bar.

An external hydraulic supply of 45 L/min at 16.5 MPa drives the station. This arrangement avoids the need for an electrical drive connection and the associated voltage and frequency matching.

The station can be considered for civil engineering, tunnel void filling, onshore and offshore filling, and compatible low-strength backfill projects. Equipment selection should account for slurry composition, delivery distance, required pressure and the available hydraulic supply.

1. Civil Engineering Filling
Preparation and pumping of compatible cement slurry for construction filling and grouting tasks.
2. Tunnel Grouting and Backfill
Delivery of suitable grout into selected tunnel gaps and cavities within the station’s operating capabilities.
3. Localized Void Filling
Mixing and supplying pumpable slurry for accessible cavities and empty spaces.
4. Low-Strength Backfill
Preparation and placement of compatible cementitious backfill formulations.
5. Onshore and Offshore Operations
Slurry filling work where suitable hydraulic power and appropriate operating arrangements are available.
Application suitability depends on material compatibility, required pressure and delivery conditions.
 

1. Integrated Grouting Station
Combines mixing, agitation and hose-pump delivery, reducing the need to arrange and connect separate machines.
2. External Hydraulic Drive
Operates from a suitable hydraulic source without requiring a site electrical connection for the drive system.
3. Recirculation Mixing Process
A centrifugal pump circulates water, cement and additives through the 220 L mixer to promote thorough blending.
4. 450 L Slurry Holding Capacity
The agitator holds prepared material and keeps it moving before delivery to the application point.
5. Coordinated Batch Handling
Separate mixing and agitation tanks allow preparation of the next batch while previously mixed slurry remains available for pumping.
6. Hose Pump Delivery
The GH32-330SR hose pump provides a specified output range of 19–38 L/min and a pressure specification of 14 bar.
7. Manual Adjustment and Monitoring
Hydraulic control valves, pressure gauges and a speed control valve support operation and system adjustment.
8. Customizable Configuration
Modifications can be discussed according to material properties, site layout and project requirements.
