POLYCRETE pump shafts
Acid does not stand a chance here
The formation of sulphuric acid by thiobacillus in waste water systems cannot always be avoided by planning. Besides the direct introduction of waste water containing sulphides, unfavourable waste water conditions such as long waste water dwelling times or insufficient oxygen supply can lead to sulphide problems. Due to the controlling framework parameters this often starts from the pump stations.
The polymer concrete material exhibits its extremely tolerance to chemicals under these aggressive environmental conditions. POLYCRETE® is most resistant to aggressive media (pH values from 1 to 12 possible) and is therefore predestined for use as a pump shaft material.
However, the special design of the POLYCRETE® pump shafts offers even more advantages. The deep installation of the shafts (caused through the creation of collection volume underneath the supply pipe level) often results in the need for expensive ground water lowering systems. Here the joint-less, mostly single-part construction of the POLYCRETE® pump shafts is worth cash money. In addition the risk of leaking at the connecting joints is eliminated. The integrated pump sump with concave moulding forms a collecting chamber without sludge deposits. Like the base plate it is made from POLYCRETE® so that the interior of the shaft is completely protected against aggressive media. Of course POLYCRETE® pump shafts are also suitable for installation as cost-efficient sunk shafts.
