A portable shotcrete machine is a compact, mobile piece of equipment designed to pneumatically or mechanically project concrete or mortar at high velocity onto a surface. It’s widely used in construction, mining, tunneling, slope stabilization, and pool building due to its versatility and ability to apply material efficiently on vertical or overhead surfaces.

An electrical refractory gunning machine is a specialized piece of equipment used in high-temperature industrial environments—such as steel mills, foundries, and cement plants—to apply refractory materials (like castables, gunning mixes, or plastic refractories) onto the internal linings of furnaces, kilns, ladles, and other vessels.

Electric refractory spraying machine uses a motor-driven rotor or vibrator to convey refractory materials (such as refractory concrete and castables) from a hopper to a spray gun. Compressed air accelerates the material at the spray gun, spraying it at high speed onto the target surface, forming a dense, uniform refractory layer. Its key advantages are:
Efficient application: Spraying rates can reach several cubic meters per minute, significantly reducing application cycle time.
Precise control: By adjusting motor speed, air pressure, and nozzle angle, material flow and spray thickness can be precisely controlled.
Adaptable to complex environments: It can operate in high temperatures, confined spaces, and on vertical or inclined surfaces, meeting diverse application needs.

A peristaltic squeeze pump is a specialized tool for pumping concrete where traditional pump valves would fail quickly due to clogging or wear. Its valveless design excels with aggressive, fiber-reinforced, or coarse mixes, particularly in medium-volume applications, confined spaces, or repair/grouting work.

A peristaltic pump, also known as a hose pump or tube pump, operates by mechanically compressing a flexible tube to move fluid through it. While peristaltic pumps are widely used in industries such as chemical processing, water treatment, and medical applications due to their ability to handle abrasive, corrosive, or shear-sensitive fluids without contamination, their use in pumping concrete is extremely limited and not common.

A peristaltic concrete pump (also called a squeeze pump or hose pump) is a specialized positive displacement pump designed to transport concrete, grout, or mortar in construction applications. Its unique operating principle—mimicking peristaltic motion (like intestinal contractions)—makes it ideal for handling abrasive, viscous, or shear-sensitive materials.

For precast concrete plants, peristaltic pumps offer a reliable, low-maintenance solution for handling abrasive, viscous concrete mixes. Their ability to deliver precise, pulsation-free flow reduces waste, improves product quality, and lowers operational costs—making them a preferred choice for high-output precast facilities. When selecting a pump, prioritize hose durability, drive system reliability, and integration with plant automation.

Squeeze concrete pump with mixer application:
Small-scale construction:
Applicable to residential construction, field construction and other scenarios, one-stop solution to concrete mixing and transportation needs.
Typical cases: on-site mixing of residential buildings, field road repairs, small bridge pouring, etc.
Special engineering needs:
Refractory material transportation: The hose material can be replaced with high-temperature resistant materials to adapt to high-temperature environments.
Corrosive environment: Acid and alkali resistant hoses are selected, which are suitable for ground pouring in chemical workshops.
Mobile operation: Some models use diesel engines to adapt to sites without power supply.
Ancillary equipment:
Arm-type material distribution booms, outriggers and other devices can be installed to form a complete pumping system to meet the needs of high-rise buildings or long-distance transportation.

Peristaltic concrete pump technology: The motor drives the roller or cam in the pump head to periodically squeeze and release the elastic hose, forming negative pressure to suck in concrete, and then discharge it through positive pressure. The hose is the only part in contact with the concrete, avoiding the wear and leakage problems of traditional piston pumps.
Mixing system: The peristaltic concrete pump is equipped with an independent mixer, which can mix cement, sand and water in real time to ensure the uniformity of concrete and prevent segregation. The mixing speed is adjustable to meet different ratio requirements.

Hose type peristaltic concrete pump with mixer is a device that combines peristaltic pump technology with concrete mixing function. It realizes concrete transportation through periodic compression of the hose and integrates a mixing system to ensure concrete uniformity. It is suitable for small-scale construction or special scenarios.

Hose pump with mixer is an engineering equipment that integrates a hose pump with a stirring device. It realizes the transportation of low-shear and high-viscosity media through a flexible hose, and is equipped with a stirrer to complete the mixing and homogenization of materials. Its core working principle is:
Mixing function:
The motor drives the stirring blade to rotate at high speed to force the liquid or paste material to mix to ensure uniformity.
It is suitable for media with high viscosity, easy stratification or containing solid particles (such as mortar, coating, food slurry, etc.).
Pumping function:
The hose pump compresses the flexible hose through the extrusion roller or sliding shoe to form a negative pressure to suck the material, and then the hose restores the deformation to generate pressure to discharge the material.
The inner wall of the hose is smooth, without valve body or seal, to avoid medium blockage or leakage, suitable for conveying corrosive, high-viscosity or fiber-containing fluids.

Hose concrete pump with mixer is an engineering machinery that integrates concrete mixing, pumping and hose transportation. It can achieve flexible material distribution at the end through the hose, which is suitable for narrow spaces or construction scenes that require manual assistance. Its core functions include:
