Construction Features :
Canned Motor Pump is a centrifugal pump with pump and hermetically sealed electric motor mounted on single shaft thus eliminating the requirement of mechanical seal or other sealing device. Entire rotating assembly is immersed in the liquid, and motor stator and rotor are isolated from the pumped liquid with corrosion resistant, non-magnetic liner and sleeve. A part of the pumped liquid is by-passed through the motor, for cooling of motor and lubricating the bearing.

Cashing :
Axial suction and top centre line delivery. Smooth hydraulic passages for high efficiency. Volute type casing connected to liner disc and adapter plate.

Impeller :
Enclosed/semi-open type, statically and dynamically balanced. Hydraulic balancing of impeller achieved by means of automatic thrust balance arrangement. Auxiliary impeller for bearing lubrication and motor cooling is also available

Shaft :
Stainless steel shaft accurately machined and ground. It is supported by ceramic/carbon graphite sleeve bearings in motor which are lubricated by pumped liquid. A return passage for circulating liquid for cooling motor and bearing lubrication available through the shaft.

Direction Of Rotation :
Clockwise viewed from driving end.

Elecric Motor :
2/4 pole, 3 phase, 415V/480V, 50 Hz/60 Hz, Class of insulation F, H or C. Flame-proof and explosion proof construction with built-in safety devices available.

Flanges :
• Standard: Drilled to ANSI-B 16.5 Class 300.
• Optional: Drilled to DIN/IS/ASA/BS.

Material Of Construction :
• Casing: Stainless Steel, CF8M, CF3M,WCB,CI
• Impeller/Auxiliary Impeller: Stainless Steel, CF8M, CF3M,WCB,CI
• Stator Liner: Hastelloy, Inconel, SS316L
• Rotor Sleeve: Hastelloy, Inconel, SS316L
• Bearing: Silicon Carbide Ceramic, Carbon graphite
• Thrust washer: Tungsten Carbide, SS316L with HCR/Ceramic coating
• Shaft Sleeve: Tungsten Carbide, SS316L with HCR/Ceramic coating.
