Albin Pump continues to set the standard for peristaltic concrete pump technology used in the construction industry.
Whether it’s for cement slurry transfer, production of chemical additives or 3D printing, we offer a wide range of technologies to satisfy your every requirement.
Read on to learn about how Albin Pump peristaltic concrete pumps are utilized in the field, and the benefits our peristaltic concrete pumps can offer you.
Cement is the main ingredient in concrete and consists of a fine powder that when mixed with water, sand, and aggregate forms concrete.
But how is cement created? It is manufactured by heating a mixture of limestone, clay, and sand into a rotating kiln at high temperatures (2640°F / 1450°C) to produce a cement “clinker.” Clinker is then cooled and ground into a fine powder, at which point it becomes cement.
Concrete is then formed by mixing cement (7-10%) with a mixture of sand and gravel (fine & coarse aggregate) and water to form a concrete slurry.
Also known as hose pumps, peristaltic pumps have been used for approximately 150 years since the late 1800s, when they were used to transfer mortar and plaster inside of buildings during construction. Hose pumps were classified as a heavy duty piece of equipment, ideal for slurry or solids handling. Since then, advanced capabilities have expanded for hose pumps as peristaltic technology has improved.
In peristaltic concrete pumps, the rollers or shoes move cement slurry through the hose or tube at high pressure, so there is no need for degassing valves. The rollers squeeze the concrete to prevent backflow, removing the need for mechanical seals, creating a seal-less system.
The rollers 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 roller or shoe rotation controls the direction of the cement slurry flow, with no internal valves needed.
