Pumping cement with a Verderair double diaphragm pump
Bentonite and mortar
A good example of pumping cement slurry with a Verderair double diaphragm pump is the spraying of walls with a mixture of bentonite and mortar. The waste of the cement slurry is collected in the basement. A Verderair double diaphragm pump moves the cement slurry out of the basement to the first floor to be removed.
Cement slurry is a very abrasive product, this can cause many problems to pump. The material choice for the wetted parts of the Verderair diaphragm pumps is huge. Ball valves, seats, diaphragms, all wetted parts are available in a large choice of materials preventing abrasion for each application. This makes the Verderair diaphragm pumps excellent pumps for pumping cement slurry. Verderair has also excellent priming capabilities to pump up the abrasive cement.
Background information Cement
Cement consists of the raw materials sand, shale, iron, ore, clay and industrial by-products. The main ingredient however, is limestone. Cement is the binding substance to keep together the raw materials (sand, gravel, crushed rocks, water and chemical additives) for concrete production. Pumping cement can cause many problems.
