Design Features

Features Benefits
Impeller Locking Mechanism Prevents catastrophic failure in case of reverse rotation
Impeller Options Option of closed and semi open impeller with efficient blade passage for effective pumping of process media
Drain plug Darin plug allows swift drainage of hazardous liquids
Polymer lined casing cover Single & Double mechanical seals can be accommodated without any modifications
Bearings Bearings capable of carrying high dynamic loads to run beyond standard lifetime (17500 hrs)
Low Stiffness Ratio shaft design Robust shaft design ensures less than 0.05 mm (0.002 in) deflection at seal faces thus maximizes seal life
Positive locking of impeller and shaft Prevents failure due to wrong rotation and ensures maximum torque transmission
Stepped sleeve Aids proper sealing at the impeller rear side and accurate alignment of rotary and stationary faces
 

Mechanical Seal

Type TB is single, outside mounted seal, uses PTFE bellows as secondary seal offering universal chemical resistance for a broad range of clean and corrosive pumping media.

Type RA is single, outside mounted seal, employs fluoroelastomer (FKM/FFKM) as secondary seal to handle highly corrosive & homogenous slurries.

Type GP is packed with resilient or semi-resilient material, provides a dynamic seal. Gland Packing is the most common and least expensive sealing for pump.
