Screw Type Secondary Structure Pouring Pump

For construction teams handling secondary structure work, time and space are always limited. Interior columns, lintels, ring beams, and basement walls are often poured in narrow areas where large machines cannot enter. The Screw Type Secondary Structure Pouring Pump is designed exactly for these conditions.

This compact machine delivers fine-aggregate concrete smoothly and continuously, helping crews reduce manual handling and speed up pouring. Whether the job is a high-rise renovation or a rural house build, this pump turns slow and tiring work into a stable and efficient process.

What is a Screw Type Secondary Structure Pouring Pump

A Screw Type Secondary Structure Pouring Pump is a compact concrete delivery machine made for fine stone concrete used in secondary structures. Unlike large piston pumps, it uses a rotating screw to push concrete forward at a steady speed.

This type of pump is commonly used as a secondary structure concrete pouring machine for indoor and small-scale construction tasks. Its small size allows it to work close to the pouring area, reducing concrete loss and site mess.

These parameters directly affect working efficiency and long-term cost.

Core Advantages Of Screw-Type Secondary Structure Pouring Pump

The Screw Type Secondary Structure Pouring Pump offers clear advantages for small and medium construction teams.

• Accurate And Smooth Delivery
  The screw structure moves concrete evenly, which helps avoid pipe blocking when pumping fine stone concrete.
• Flexible For Tight Spaces
  The compact body fits well in narrow indoor areas, making it ideal for columns, beams, and small wall sections.
• High Working Efficiency
  Continuous pouring reduces waiting time between batches and keeps workers focused on finishing tasks.
• Easy Maintenance
  The modular design lowers repair costs and helps extend the service life of the machine.

These advantages make it a reliable choice for daily secondary structure work.

How A Screw Concrete Pump Works

A screw concrete pump uses a different working method compared to piston pumps. Its design focuses on smooth flow and simple operation.

Screw Blade Pushing Principle

The rotating screw blade pushes concrete forward inside the pipe. This movement is steady and controlled, which helps keep the concrete flow stable and reduces pressure changes.

Hydraulic Drive Power

The hydraulic system provides strong and stable power to the screw. It allows the pump to work continuously without sudden stops, even during long pouring tasks.

Hopper And Pipeline Design

The hopper and delivery pipe are matched to fine concrete materials. This helps concrete enter the screw smoothly and reduces wear on internal parts.

Together, these systems ensure reliable performance on secondary structure projects.

Ideal Application Scenarios For A Small Concrete Pump

As a small concrete pump, this machine is suitable for many practical construction situations.

Residential And Office Secondary Structures

Used for pouring structural columns, lintels, and ring beams inside buildings, especially during renovation or expansion work.

Narrow Space Construction

Basements, old city renovation sites, and village housing projects often have limited space. The pump can be placed close to the work area.

Small Infrastructure Projects

Ideal for rural housing, fence foundations, and small concrete bases where large pumps are not economical.

Emergency Repair Jobs

For quick concrete repair and reinforcement tasks, the pump can be set up fast and start working immediately.

These scenarios highlight the pump’s flexibility and practical value.

When Not To Use A Screw-Type Secondary Structure Pouring Pump

This machine is designed for specific tasks and is not suitable for all concrete jobs.

It is not recommended in the following cases:

• Large Aggregate Concrete
  Concrete with stone size over 20 mm may cause the screw to jam.
• Long Distance Or High Lifting
  For distances over 50 meters or lifting heights above 15 meters, piston pumps are a better choice.
• Large Continuous Pouring Projects
  Projects requiring over 50 cubic meters per day may exceed the pump’s efficient working range.

Choosing the right pump for the job helps avoid delays and equipment damage.

Maintenance Tips For Long-Term Performance

Proper maintenance helps the pump stay reliable over time.

Daily and regular care includes:

• Cleaning the hopper and screw after each job
• Checking the hydraulic oil level and seals regularly
• Replacing wear parts based on usage frequency

Simple daily maintenance can greatly reduce downtime and repair costs.
