Product Overview
YPPC MAG. DRIVE PUM
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
PERMANENT RARE EARTH MAGNETS
Standard ANSI MKIII casings.
Available in complete range of
alloys.
High energy magnets can driver synchronously
wetted shaft and impeller.
NdFe and SmCo materials are available.
IMPELLER
SINGLE ROW RADIAL
BEARINGS
Standard ANSI MKIII
impellers.Available in
complete range of alloys.
Long life radial bearings.
Reverse vane and open
impellers are all available.
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
DRIVE SHAFT
Torque transmission and
shaft key are equal ANSI
standard pumps.
DOUBLE LIP OIL SEAL

YPPC MAG. DRIVE PUM
Bearing Holder
• One holder can use all 1M
pumps
• Two SiC bearings set into
holder
• Two flush inlets introduce
high
pressure from impeller
vane tip
to SiC bearings
• One hole is located at the
top for
air vent in containment
shell
• Anti-rotation pins prevent
SiC
bearings rotation
