NJRP SeriesStandard Chemical Process Pumps - Frame Type
NJRP Series pumps are injection moulded, horizontal, back pull-out, volute casing type, single stage, center line discharge, end-suction centrifugal pumps. Cast iron frames with injection moulded wetted parts are designed to handle higher hydraulic pressures and flange loads suitable for hazardous, corrosive and toxic media. Dimensional and design criteria of NJRP pumps conform to ISO 2858 / ISO 5199 / EN 22858.

Design Features
Injection moulded, center line discharge in frame type construction handles higher hydraulic pressures and flange loads with ease
Effectively collects process media from exit of the impeller and delivers to discharge connection
High wall thickness of non metallic wetted parts (Min 10 mm) maximizes pump life for corrosive applications
Option for drain plug for easy & safe maintenance
Stepped sleeve aids proper sealing at the impeller rear side and accurate alignment of rotary and stationary seal faces
Injection moulded casing cover with sole plate 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)

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.
