Product Overview
NJL Series pumps are fluoropolymer lined, horizontal, back pull-out, volute casing type, single stage, center line discharge, end
suction centrifugal pumps. Fluoropolymer lined pumps are excellent alternates to expensive super alloy pumps for hazardous,
corrosive and toxic media. Dimensional and design criteria of NJL pumps conform to ISO 2858 / ISO 5199 / EN 22858.

mic loads to run beyond standard
universal chemical resistance for a broad range of clean & corrosive pumping media.
Type RA is single, outside mounted seal, employs fluoroelastomer (FKM/FFKM) as
secondary seal to handle highly corrosive & homogenous slurries.
Type DROTT is double, back to back arrangement seal; using fluoroelastomer (FKM /
FFKM) & fluoropolymer (PTFE) as secondary seals suitable for handling hazardous
chemicals, media with tendency to crystallize and to avoid dry running while pumping
