Design Features
Heavy, center line discharge with unique volute casing design in fluoropolymer lined construction provides high pressure handling capability & efficient and smooth transfer of pumping media from exit of the impeller to delivery
High fluoropolymer liner thickness (Min 6 mm) maximizes pump life for corrosive & erosive 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
Volute CasingImpellerImpeller InsertCasing CoverGasketO-RingsShaft Sleeve Bush Stationary Unit Rotary Unit Seal Cover Hose Barb Nipple Lantern Bearing Pedestal Bearings Oil Seal Bearing Cover (OB)Bearing Cover (IB)Support Foot Constant Level Oiler Keys & Fasteners
Fluoropolymer lined casing cover 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
Axial forces are balanced with balancing holes / back vanes
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.
