No mechanical seal — leak risk disappears
The drive between motor and impeller is provided by a magnetic field; there is no such thing as seal wear or a seal leak.

Magnetic-Coupled Acid Pumps
Magnetic-coupled pumps are fully leak-free centrifugal pumps that drive the impeller through a magnetic coupling, with no mechanical seal between motor and impeller. They are preferred for the safe transfer of acids, bases and other corrosive chemicals, for a design that eliminates leak risk entirely; supplied with PP, PVDF or PFA-lined casing options.

Why it matters
What does a magnetic-coupled pump do?
Having no mechanical seal, it carries acids and corrosive chemicals with no leak risk.
Materials suited to acids and corrosive chemicals
With PP, PVDF or PFA-lined casing options, it gives high chemical resistance against strong acids and bases.
Low maintenance needs
With no wearing seal part, periodic seal replacement and the associated maintenance cost disappear.
The magnetic coupling acts like a safety valve
If the pump is overloaded, the magnetic coupling slips, protecting the motor and pump from possible mechanical damage.
Types
Sub-types of magnetic-coupled pumps
All three run seal-less; what sets them apart is the casing material and resistance level.
Plastic-casing (PP/PVDF) magnetic-coupled pump
A lightweight, economical solution for transferring moderately corrosive acids and chemicals.
- Lightweight construction
- Wide chemical compatibility
- An economical solution
PFA-lined magnetic-coupled pump
Preferred against very strong acids and corrosive chemicals for the superior chemical resistance of its PFA lining.
- Superior chemical resistance
- High-purity processes
- Long service life
Metallic magnetic-coupled pump
Used on process lines that need high temperature and pressure, for the mechanical strength of its metallic casing.
- High-temperature resistance
- High pressure capacity
- Heavy-duty process conditions

FAQ
Questions from the field
The questions we hear most often when quoting magnetic-coupled pumps.
Why does being seal-less matter?
Pumps with a mechanical seal carry a leak risk as the seal wears over time; with magnetic-coupled pumps this risk disappears entirely, which increases safety with corrosive and hazardous chemicals.
Which chemicals is it resistant to?
This depends on the casing material; PVDF and PFA-lined types show high resistance to strong acids, bases and oxidizing chemicals.
Is there a dry-running risk?
In standard types, prolonged dry running can overheat the magnetic coupling; on critical lines, dry-run protection (a level switch) is recommended.
How often does it need maintenance?
Since there is no seal, maintenance needs are low; the bearings and magnetic coupling should still be checked periodically.
Do you only serve Istanbul?
No. While our office is on Istanbul's Anatolian side (Ataşehir), we supply and ship across Istanbul's European side, the surrounding provinces and the Marmara region, and Turkey as a whole — covering your equipment end to end, from a single source.
