Global centrifugal pumps from Verder are able to convey all types of thermal oil at temperatures ranging from -80 to 250C. They incorporate a unique sleeve-bearing design that enables the pump to cope with thermal shocks encountered during rapid changes in operating temperature. The high-grade, silica-free, silicon carbide bearing components are mounted on O-ring elastomers. This allows thermal expansion and distortion without causing damage. It also eases the replacement of the silicon carbide components. The elastomer material is selected to accommodate the pumping temperature range and to give the best compatibility with the transferred liquid. There are no special tooling requirements for maintenance, commissioning, inspection or complete re-assembly of the pump unit.
