Features and benefits
• Optimized hydraulics in housing and impeller ensures unimpeded fluid flow
• O-ring seal between pump housing and cover, so there is no risk of leakage
• Impeller housing and wear ring made of different materials, provides improved corrosion resistance and no 'sticky' elements
• Back pull-out design for easy disassembly for service
• The pump is electrophoretically coated for increased corrosion resistance
• PN 10 and 16 bar
