Corrosion Resistant Chemical PumpsArmour Type

NJK Series pumps are injection moulded, horizontal, back pull-out, volute casing type, single stage, center line discharge, end-suction 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 2858 / ISO 5199 / EN 22858.

Impeller Locking Mechanism Prevents catastrophic failure in case of

reverse rotationOption of closed and semi-open impeller with efficient blade passage for effective pumping of process media

Impeller Options Drain Plug Drain plug allow swift drainage of hazardous

liquids

Design Features

Stepped sleeve aids proper sealing at the impeller rear side and accurate alignment of rotary and stationary seal faces

Injection moulded casing cover with rear armour to accommodate single & double mechanical seals without any modifications

Back pull out design provides safe, simple and quick assembly & disassembly of pump

Robust shaft with low stiffness ratio to ensure less than 0.05 mm (0.002 in) deflection at seal faces thus maximizes mechanical seal lifePositive locking of Impeller & shaft prevents failure due to wrong rotation and ensures maximum torque transmission

Hydrodynamically optimized, closed / semi-open radial impeller designed for

Optimum suction behaviour with low NPSH requirement

Low noise and vibration

Minimum axial loading on bearings and seal

Lantern provides accurate alignment between casing and bearing bracket

Large openings on both sides, top and bottom to easily access seal unit for maintenance & connection of auxiliary support units

Heavy duty bearing bracket & cover provide rigid support to shaft and bearing assembly

Large capacity oil sump results in effective heat transfer for cooler bearings & extends bearing life

O-ring seal between bearing bracket and cover & lantern to prevent leakage of lubrication oil

Standard lip type shaft seals at pump & coupling end ensure leakproof environment for complete safety

Telescopic arrangement for semi-open impeller enables adjustment of impeller front clearance to obtain optimal hydraulic performance

Bearings Capable of carrying high dynamic loads to run beyond standard lifetime (17500 hrs)

Mechanical Seal Options

Type TB is single, outside mounted seal, uses PTFE bellows as secondary seal offering 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 volatile liquids. Compatible pressurized buffer liquid needs to be circulated via thermosyphon or other external pressurized systems.
