Introduction

Introduction

  • 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 features

CASING

Standard ANSI MKIII casings. Available in complete range of alloys.

PERMANENT RARE EARTH MAGNETS

High energy magnets can driver synchronously wetted shaft and impeller.

NdFe and SmCo materials are available.

IMPELLER

Standard ANSI MKIII impellers.Available in complete range of alloys.

Reverse vane and open impellers are all available.

SINGLE ROW RADIAL BEARINGS

Long life radial bearings.

BEARING HOUSING

Oil bath, oil mist and grease lubrications are available.

ADJUST SHIM PLATES

Adjustable shim plates can set impeller clearance.

INTERNAL FLUSHING PATH

Lubricate SiC bearing. External flushing is available.

CONTAINMENT SHELL

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

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.

SILICON CARBIDE BEARINGS

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

Major Design Features
