Specifications

Ammonia, Freon and other chemical Pumps for Refrigeration and Chemical plants. Perfect exprosion & leak proof, Self lubrication.

A canned motor pump is a combination of a centrifugal pump and a squirrel cage induction motor built together into a single hermetically sealed unit. The pump impeller is normally of the closed type and is mounted on one end of the rotor shaft that extends from the motor section into the pump casing. The rotor is submerged in the fluid being pumped and is therefore "canned" to isolate the motor parts from contact with the fluid. The stator(C) is also "canned" to isolate it from the fluid being pumped. Bearings(D) are submerged in system fluid and are, therefore, continually lubricated.
The canned motor pump has only one moving part, a combined rotor-impeller assembly that is driven by the magnetic field of an induction motor. A portion of the pumped fluid is allowed to recirculate through the rotor cavity to cool the motor and lubricate the bearings. The stator windings and rotor armature are protected from contact with the recirculating fluid by a corrosion resistant, non-magnetic, alloy liner that completely seals or "cans" the stator winding.
Modifications to the recirculation flow system are available to allow canned motor pumps to be used in any application including fluids up to 842°F (450°C), volatile liquids, and liquids with solids.

Features of Halla Canned Pumps
--------------------------------------------
1. Perfect Explosion Proof
Proof-Explosion motor strictly tested by Korea Occupational Safety & Health Agency

2.Perfect Leak Proof
No mechanical seal needed, Since pump and motor built together into a single hermetically sealed unit.

3.Self Lubrication
Prevent contamination of liquids pumped with Lubrication oils, since the liquids pumped themselves lubricate bearings.

4.Compact Design
Save installation cost since pump and motor built together into a single hermetically sealed unit.

5.Low Noise & Vibration
Provide pleasant operation surroundings, since there are no motor fan and shaft stand that cause Noises

6. Durable Spare Parts
Save maintenance cost with more durable spare parts such as resin impregnated carbon bearings and specially coated sleeves, washers

7. Variable Standard Flange
Save piping cost with variable standard flange. ANSI, JIS, DIN..
