High pressure plunger grout pump delivers compatible cement and bentonite-based mixtures for foundation treatment, tunnel grouting and underground filling. Its hydraulic double-plunger design provides stepless pressure and flow adjustment, allowing delivery to be matched to different injection stages. Powered by a 15 kW motor, the pump has a specified output range of 0–90 L/min and a pressure range of 0–100 bar. The pumping assembly features 85 mm plungers, a 190 mm stroke and ball valves, with a maximum permitted particle size of 8 mm. Two pulsation dampers help moderate delivery fluctuations during operation.

Applications of the double-plunger injection system:
Tunneling and underground engineering: Shield tunneling synchronous grouting, pre-support grouting (pipe roofing), and backfill grouting behind tunnel linings; ensures precise control of surface settlement and supports uninterrupted, high-flow continuous operations.
Mining engineering: Underground rock strata water-blocking and reinforcement, and goaf (mined-out area) infill grouting; explosion-proof double-plunger systems operate safely in high-gas environments, significantly reducing the frequency of underground equipment maintenance.
Water conservancy and hydropower engineering: Dam foundation curtain grouting and dam body seepage-proofing/reinforcement; stable high-pressure output ensures grout penetrates fine rock fissures, enhancing the seepage-proof performance of dam foundations.
Specialized engineering: High-pressure jet grouting, precision chemical injection for oil and gas fields, micropile foundation anchoring grouting, and borehole wall stabilization/leak sealing; suitable for a wide range of high-precision, high-pressure injection applications.

A low-wear plunger type grout pump is designed with attention to the components exposed to abrasive grout. For contractors handling cement and bentonite-based mixtures, wear performance affects maintenance frequency, pumping consistency and equipment availability throughout the project.

A pneumatic refractory mixing pump is a specialized piece of equipment designed specifically for refractory material mixing operations, powered by compressed air. It is widely used in the metallurgical and building materials industries for mixing refractory castables, refractory mortar, and other materials. It can also be equipped with pipelines for short-distance material transport, replacing traditional manual handling and significantly improving construction efficiency.

Container-type bentonite grout batching plants are containerized bentonite slurry mixing plants that integrate the slurry mixer and agitator within a standard container. Their biggest advantage is their ease of relocation; they can be directly hoisted onto the construction site and used immediately. This makes them particularly suitable for construction projects requiring frequent relocation or with limited space. They can be used to prepare bentonite slurry cement grouting materials, etc. Bentonite is commonly used in engineering as a mud wall protection, seepage prevention grouting, or auxiliary material in shield tunneling, and is typically used in shield tunnel projects.

A tunnel grout station is a complete set of equipment for grout preparation, storage, and high-pressure grouting in tunnel construction. It is mainly used for: grouting of pre-support (pre-support small guide pipes, pipe roof); grouting of backfill behind initial support; grouting of surrounding rock consolidation (water plugging + reinforcement); grouting of backfill behind secondary lining; and water plugging grouting in karst, water-rich faults, and fractured zones.

High pressure grouting pump applications: Foundation Reinforcement: Grout fills soil pores to form a composite foundation, increasing bearing capacity. Seepage Prevention and Leakage Repair: Under high pressure, the grout penetrates into micro-cracks, forming a dense curtain to prevent groundwater seepage. Structural Strengthening: Grouting repairs existing building foundation cracks, restoring structural integrity.

500 liter high-shear UHPC planetary mixer

The 1000L planetary concrete mixer achieves seamless mixing of materials in three-dimensional space through the dual motion of the mixing arms’ rotation and revolution. The revolution direction is opposite to the rotation direction, and each mixing element rotates in a different direction, creating complex convection, shearing, and extrusion effects to ensure a mixing uniformity of ≥98%.

1000L planetary mixer for refractories adopts a planetary mixing device, through self-rotating and public-rotating dual motion tracks, to achieve full mixing of materials in three-dimensional space. Compared to traditional disk-type mixers, the mixing resistance is smaller, the mixing efficiency is increased by more than 30%, and it ensures that refractory materials (such as fireproof materials, plastic) achieve high uniformity in a short time.

Concrete spraying machine is essential for lining tunnels, and the process is commonly known as shotcreting. This method is widely used in tunnel construction for ground support, stabilization, waterproofing, and structural reinforcement.

Pea stone shotcrete machines must be capable of spraying concrete containing pebbles (typically 5-20mm in size). Their pumping system must thoroughly mix the aggregate with cement slurry using high pressure (10-25 MPa), ensuring a shotcrete layer density of ≥95%.
Main application scenarios include:
Tunnel/mine support: Spraying pebbles to create a flexible support layer that adapts to geological deformation.
Slope reinforcement: Spraying fiber-reinforced concrete containing pebbles to improve shear strength.
Building exterior wall restoration: Spraying pebbles to create a finishing layer for enhanced durability.

Concrete sprayers use high-pressure spraying technology to evenly apply concrete or mortar to target surfaces. They are widely used in tunnels, mines, slope reinforcement, building exteriors, and underground structures. Their core advantages include: Efficient construction: Spraying speeds far exceed those of traditional manual plastering, enabling a daily production capacity of hundreds of square meters.
Optimized quality: Reduced material waste (rebound rate as low as 5%-15%), high-density spray coatings, and improved impermeability by over 30%.
Adaptable to complex structures: Precisely conforming to curved and irregular surfaces (such as tunnel vaults) without the need for formwork support.

Pea Gravel Concrete Spraying Machine is a kind of mechanical equipment specially used for spraying gravel concrete (or concrete containing aggregate). It is widely used in support operations in underground engineering and civil engineering fields such as tunnels, subways, culverts, and slope protection.

The shotcrete system used by TBM (Tunnel Boring Machine) is a key equipment for timely support of surrounding rock in tunnel construction. Its core function is to mechanically spray concrete at high speed onto the excavation surface to form a support layer to stabilize the surrounding rock.

The slurry and bentonite grout mixer is a core piece of equipment used to efficiently mix cement-based or chemical grouts with bentonite in soil enhancement projects. It significantly improves slurry uniformity, stability, and construction efficiency through high-shear and colloidal mixing technologies.

In soil improvement projects, the improved grout mixing plant is the core fully automatic cement bentonite grouting mixing equipment, which can efficiently complete the mixing of cement, bentonite, lime and other materials. It is suitable for foundation reinforcement, road base, tunnel grouting and other scenarios.

The fully automatic cement grout mixer is a modern engineering equipment that integrates grouting and grouting. It realizes efficient and accurate preparation and transportation of cement-based slurry through automated control. It is widely used in reinforcement and anti-seepage projects in tunnels, water conservancy, transportation and other fields.

Cement grouting injection mixer is widely used in foundation reinforcement, anti-seepage and leakage plugging, and rock filling projects in the fields of construction, water conservancy, transportation, mining, etc.

Bentonite clay grouting mixing plants use high shear forces to break up bentonite particles and ensure they are thoroughly mixed with cement and water to form a uniform slurry. Some equipment, such as AMIX Systems’ colloid mixers, utilize high-shear mixing technology to fully hydrate the bentonite in under two minutes, improving slurry quality.

A peristaltic pump is an excellent and widely used choice for wastewater treatment transfer applications, especially when handling challenging fluids like sludge, chemicals, scum, or abrasive/viscous slurries.

Peristaltic pumps are successfully used in thickener discharge for:
Gold and silver leach plants (cyanide slurries)
Copper and base metal concentrators
Iron ore processing
Coal tailings management
Mineral sands and heavy media recovery

Peristaltic (hose) pump is a highly suitable and commonly used solution for pumping sludge containing fines and brine, especially in harsh or corrosive environments. This technology offers reliability, low maintenance complexity, and excellent chemical/abrasion resistance—making it a top contender for this challenging application.

When selecting a peristaltic pump for pumping mortar (a thick, abrasive mixture of cement, sand, and water), the focus must be on abrasion resistance, pressure handling, and durability to manage the challenges of mortar’s viscosity, particle size, and alkaline nature.

Peristaltic pumps are very well-suited for many ceramic slip transfer applications, particularly where gentle handling, ease of maintenance, self-priming, and handling of abrasive slurries are priorities. Their main drawbacks are tubing wear (a consumable cost) and pressure/flow limitations compared to some other pump types (like progressive cavity pumps).

A hose peristaltic transfer pump (also known as a peristaltic hose pump or tube pump) is a type of positive displacement pump that moves fluids by mechanically compressing and releasing a flexible rubber hose. As the pump rotor turns, rollers or shoes squeeze the hose, pushing the fluid forward in a gentle, pulsating flow.

Hose peristaltic transfer pump ideal applications:
A hose peristaltic pump excels in scenarios where traditional piston or screw pumps struggle:
Specialty & Confined Space Placement: Pumping into narrow forms, complex geometries, or tight access areas where maneuvering a traditional pump’s boom/pipe is difficult.
Grouting & Anchoring: Pumping cementitious grouts, micro-piles, soil stabilization, and rock annotation.
Concrete Repair & Refurbishment: Mortars, shotcrete (when equipped with an acceleration nozzle), resurfacing materials, and patch repairs.
Precast & Architectural Concrete: Smaller-scale production of countertops, panels, and decorative precast elements.
Fiber-Reinforced Concrete (FRC): Handles fibers significantly better than piston pumps prone to valve clogging.
Low-Volume Projects: Jobs where the high setup cost and complexity of a large piston pump aren’t justified.
Abrasive/Corrosive Mixes: Applications where component wear from abrasive aggregates or corrosive additives is a major concern.

A peristaltic squeeze pump for concrete (also called a concrete hose pump or squeeze pump) is a specialized positive displacement pump designed to reliably transport abrasive, viscous, or coarse concrete mixes. 

Grouting mixing plant applications: Civil Engineering: Foundation stabilization, tunnel grouting, dam waterproofing. Mining: Sealing fractures, ground control. Geotechnical: Soil compaction, void filling. Infrastructure Repair: Crack injection, slab lifting.

An electric grouting mixing plant is a piece of specialized equipment that mixes cementitious materials (such as cement, fly ash), water, and additives in a certain proportion to form grout, which is then used for grouting operations in engineering projects such as foundation stabilization, tunnel lining, and waterproofing.
