A pure thing


Respect for nature and a growing environmental awareness place high demands on manufacturers and service companies of water treatment plants/systems worldwide.



A “scraper bridge” is a mechanical construction forming an integral part of a waste-water treatment plant.  It is used for clearing sediment into a sludge collector pit or alternatively for depositing floating substances into a scum removal container. Wheels are in place for the permanent powering of the “scraper bridge”. The challenge in this design is to develop wheels that ensure operation 24/7 in extreme weather conditions and in a highly corrosive environment.



Heavy load wheels made from Vulkollan® offer the right solution in these applications! The wear resistance, high carrying capacity and low rolling resistance, together with a water repellent adhesion primer (EP), a hydrolysis repellent additive (Stabaxol) and an anti-corrosive paint system (Colturiet) for the metal wheel core, guarantee optimal reliability.



For installers, water associations, operators and service companies, this Vulkoprin wheel system offers a reliable 24/7 solution and maximum service life.



Reliability and serviceability are greatly appreciated on these installations that are not permanently manned but must be operational 24/7. An extra plus, compared to rubber tires, is that the low rolling resistance of Vulkollan® requires less energy to power the system.
