3 Standard Chemical Process Pumps - Armour Type Product Overview NJK Series pumps are injection moulded, horizontal, back pull-out, volute casing type, single stage, center line discharge, endsuction centrifugal pumps. Cast iron armours with injection moulded wetted parts are designed to handle higher hydraulic pressures and flange loads. NJK pumps are excellent alternates to expensive super alloy pumps for hazardous, corrosive and toxic media. Dimensional and design criteria of NJK pumps conform to ISO 8 / ISO 5199 / EN 28.

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 volatile liquids. Compatible pressurized buffer liquid needs to be circulated via thermosyphon or other external pressurized systems.
