Tough – New Materials for Wear-Resistant Plastic Pump
In production and processing plants in the process industry,
metallurgy and environmental technology, sophisticated media are often conveyed:
extremely corrosive and with a high solids content. For these conditions Plastic Pump(KEXON) are required,
which do not give in even under the most difficult conditions.
Wear resistant pumps for the most difficult applications
A big problem: While conveying aggressive media, the materials in contact are under a very strong, continuous load. In case of wrong material selection, damage to hydraulic or sealing parts are the consequence, it threatens pump leakage. The repairability is correspondingly high, often even the complete pump has to be replaced. The follow-up costs of a pump standstill, from repair costs to loss of income, impinge on economic efficiency and are immense for the company concerned. A pump technology, which Rheinhütte Pumpen specially designed for conveying abrasive media, promises help. The internationally experienced expert in this field has more than 150 years of practical experience and a comprehensive material expertise in metal, plastic and ceramics. Customers worldwide benefit from individual solutions for their particular conveyance process. Just like Vesuvius, where two free flow pumps of the same size were tested at two different locations –and in two different material versions.
At the first location the centrifugal pump conveys a solid suspension into a tank at a higher level. The procedure is repeated five times per hour. The pumped medium is highly abrasive at the points in contact with the medium. At this position, a free flow pump was installed with components in contact with media made of PE1000R material, a special polyethylene, that offers up to 30% higher resistance than conventional PE1000 material.
At the second location a similar suspension is pumped – with higher solids content and a significantly higher viscosity. This machine switches on every two minutes for about 25 to 60 seconds: More than 150 switching cycles can occur in an 8-hour shift. The pump is always exposed to an increased counter pressure. At the moment of maximum pumping pressure the medium only circulates within the volute casing with all the solids. The metal pump which had been used previously only withstood about 6 months. As an alternative solution, a pump technology with the even more wear-resistant multi-component material Polymercarbid was used here.
