Performance data
Fields of application for lined magnetic
drive process pumps
Leckage-free process pumps are particularly
suitable for pumping corrosive, environmentally
critical and high-purity liquids:
E In the chemical industry
E In the pharmaceutical industry
E In the petrochemical industry
E In the semiconductor industry
E In the pulp and metal industry
E In the food processing industry
E In the waste disposal/recycling industry
The SLM NK (ISO/DIN) and SLM AK (ASME/
ANSI) series were developed for use with liquids
where stainless steel and conventional
plastics such as PE, PP etc. do not have sufficient
corrosion resistance.
They are also an alternative to:
E pumps made of expensive long-lead-time
metals (Alloy C, titanium, nickel, etc.)
E mechanical seal pumps
E full plastic pumps
E metal pumps with double mechanical
seals and liquid sealing or quenching
systems
E and stainless steel magnetic drive pumps.
Design
E Sealless, fluoroplastic-lined, magnet drive
centrifugal pumps
E Dimensions and performance data to DIN
EN ISO 2858 und ASME / ANSI B73.3
E Close-coupled and frame-mounted designs
E No dynamic seal
E Isolation shell without eddy current losses
Bearing support: ISO / DIN SLM NKS
ASME / ANSI SLM AKO
Close-coupled: ISO / DIN SLM NKB
ASME / ANSI SLM AKB
Lining: Perfluoralkoxy (PFA)
ATEX and TA-Luft
conformity (clean air act)

Construction details SLM NK / SLM AK
1. Virgin PFA lining without fillers – perfect
lining quality with steady lining thickness
E Highest chemical resistance
E Temperatures up to 150 °C (300 °F)
E Full FDA conformity
E Neutral to pure and high-purity fluids in
pharmaceutical, fine chemical and semiconductor
applications
E Superb permeation resistance
E Wall thickness of at least 3 to 5 mm
(0.1 to 0.2 inch)
E Vacuum-proof anchored housing lining *
2. Journal bearing
E Journal bearing and axle carrier are made of
silicon carbide (SSiC). The proprietary
surface impregnation is extremely wear and
chemical resistant
3. Capable of handling fluids containing solids
E Solids restriction rings in the housing and rotor
prevent critical solid particles from entering the
isolation shell area
4. Axially thrust-optimised rotating unit: Smooth
running even under critical load conditions
E The shaft made of SSiC is optimally supported
in the isolation shell and in the spider without
any shaft deflection
E The large space between the SSiC sleeve bearings
provides reliable distribution of the radial
forces
E Closed impeller
5. Easy of maintenance
E Double “back pull-out” design for easy maintenance
without releasing the system pressure
E Few components only: a service-friendly pump
* For vacuum services please contact manufacturer
6. Solid design for dimensional stability even at
high temperatures
E Full-surface ductile cast iron EN-JS 1049/ASTM
A395 absorbs pipework forces and eliminates
need for expansion joints
E Impeller magnet assembly with large metal
core
7. Non-metallic double isolation shell system
E Wetted: thick-walled virgin PTFE
E Pressure-containing: carbon-fibre, with high
safety margin
E No eddy current losses: no heating of fluid,
no waste of energy
E Integral flow breakers prevent abrasive
circulation in the isolation shell
8. High-performance NdFeB (neodymium iron
boron) and SmCo (samarium cobalt) permanent
magnets
E Consistent magnetic energy density even at
high operating temperatures
E Patented magnet fixation underneath the
PFA lining
9. Outer magnet carrier with rub ring
E In event of roller bearing failure the isolation
shell will be reliably protected against damage
by a possibly tumbling outer magnet carrier
10. Impeller/inner magnet carrier assembly
of two pieces
E In case of torque adjustment or wear the wetted
rotor components can be replaced individually.
This enhances cost-efficiency
E Completely homogenous PFA lining
E No weldings
