YPPC MAG. DRIVE PUMP

IntroductionIntroduction

• Definition of Magnetic drive pump

-. A type of Sealless Pump -. Utilizes an outer ring of permanent

magnets to drive an internal rotating assembly consisting

of an impeller, shaft, and inner drive member through

a corrosion resistant containment shell

• Application

-. Hazardous and toxic fluids -. Heat transfer fluids -. Where high seal maintenance costs

are considerations • Requirement for sealless pumps

-. Based on the need for a clean and safe environment

Major Design FeaturesMajor Design Features

BEARING HOUSING

Oil bath, oil mist and grease lubrications are available.

SINGLE ROW RADIAL BEARINGS

Long life radial bearings.

DRIVE SHAFT

Torque transmission and shaft key are equal ANSI standard pumps. DOUBLE LIP OIL SEAL

Protects dust and mist from outside. Bearing isolators can increase bearing life.

PERMANENT RARE EARTH MAGNETS

High energy magnets can driver synchronously wetted shaft and impeller.

NdFe and SmCo materials are available.

SILICON CARBIDE BEARINGS

Designed for long life under maximum radial and thrust load conditions.

CONTAINMENT SHELL

One piece formed designed. Stainless steel and Hastelloy C276 are available.

INTERNAL FLUSHING PATH

Lubricate SiC bearing. External flushing is available.
