MDF-L Series - Magnetic Drive Pumps

DRY RUN CAPABLE FOR HANDLING TOUGH CHEMICALS

MDF-L is a family of compact close-coupled pumps incorporating patented repeatable, dry run technology. ETFE fluoropolymer wetted materials give MDF-L pumps excellent corrosion resistance to handle the most difficult chemical processes.

Modular construction simplifies pump maintenance, reduces parts cost and downtime. Casing liners, impellers, bearings and thrust surfaces are individually replaceable.

ETFE wetted parts make MDF-L pumps ideal for chemistries like HF, HCL, H2SO4, NaOH and others.

Installation time and maintenance time are reduced with our compact, close-coupled design.

Operating costs are reduced thanks to simple, modular construction and individually replaceable parts.

Patented pinpoint bearing system defends MDF-L pumps from dry run abuse. MDF-L pumps equipped with carbon bearings can be run dry without damage.
