Peristaltic Concrete Pumps and Cement Pumps for Construction

Cement is the key ingredient in concrete. It is a fine powder that reacts with water to bind materials together. Cement is produced by heating a controlled mixture of limestone, clay, and sand inside a rotating kiln at very high temperatures. This process creates a material called a clinker.

After cooling, the clinker is finely ground to produce cement powder. Concrete is then made by mixing cement with sand, gravel, and water. The result is a concrete slurry that must be moved, dosed, or processed accurately during production and construction.

Because cement and concrete slurries are abrasive and often thick, they require robust cement pumps and concrete pumps that can handle solids without clogging or excessive wear.

In peristaltic concrete pumps, the shoes move cement slurry through the hose at high pressure, so there is no need for degassing valves. The shoes squeeze the concrete to prevent backflow, removing the need for mechanical seals, creating a seal-less system.

The shoes compress the hose and eliminate internal backflow through the pump. They work similarly to a rotary pinch valve with ±1% repeatability. The movement of the shoe rotation controls the direction of the cement slurry flow, with no internal valves needed.

• Cement slurry transfer
• Cellular concrete manufacturing
• Production of chemical additives such as: ·
  • Flocculant, coagulant, color enhancers, strengtheners
  • Accelerant to reduce dry time inside burner during production
• Wastewater or cleanout such as:
  • Dewatering (filter press)
  • Truck washout containing sand, silt, sediment
  • Granite cutting, stone fabrication, and glass cutting
• Filter press applications for cement laitance
• Concrete coloring or batching
• 3D printing using mortar or concrete
