— MAGNETIC DRIVE CENTRIFUGAL PUMPS
Sealless. Hermetically sealed.
Zero leakage.
MAGSON magnetic drive centrifugal pumps eliminate the shaft seal entirely, the primary failure point in conventional centrifugal pumps. A magnetic coupling transfers torque contactlessly through a hermetically sealed containment shell. No seal means no leakage path. Droplex is the authorised MAGSON channel partner across East Africa.
— THE OPERATING PRINCIPLE
How a magnetic drive
pump works.
- Motor drives the outer magnet
The motor shaft connects to an outer rotating drive magnet outside the containment shell. - Magnetic coupling transfers torque contactlessly
The outer magnet drives an inner magnet through the containment shell wall; no physical contact, no shaft penetration. - Inner magnet drives the impeller
The inner magnet, inside the sealed pump chamber, drives the impeller to move the fluid. - Containment shell hermetically isolates the fluid
The pump chamber and drive are completely sealed. No shaft passes through. No seal to fail. No leakage path exists.
No shaft seal. No leakage path. No seal failures to manage.
— KEY BENEFITS
Why plants specify
magnetic drive pumps.
1️⃣ Zero leakage
No shaft seal means no leakage path. Critical for toxic, hazardous, and high-value fluids where any leakage is a safety incident or a compliance failure.
2️⃣ Minimal maintenance
No dynamic seal to inspect, replace, or adjust. The primary maintenance driver in conventional pump installations is eliminated entirely.
3️⃣ ATEX certified options
MAGSON MML and MMT are available with ATEX certification for flammable and explosive media in hazardous area classifications.
4️⃣ Handles crystallizing media
No shaft seal to block or crystallise. MAGSON magnetic drive pumps handle crystallisation-prone fluids that destroy conventional sealed pumps rapidly.
5️⃣ Back-pullout design
From size BG4 upward, the entire drive assembly can be removed without dismantling the pump unit or breaking the pipework connection.
— THE MAGSON PRODUCT RANGE
Two material groups; plastic & stainless steel.
Eight models.
Select by material group first.
- Plastic for aggressive corrosive media
- Stainless steel for higher pressures, temperatures, or where plastic is not chemically suitable.
Droplex will specify the right model for your fluid, flow rate, and operating conditions.
1. MAGSON Plastics — PP / ETFE / PVDF
For highly corrosive acids, alkalis, solvents, and chemically demanding liquids. Suitable for crystallising media. MAGSON MA, MAS, MAU, MP, MPT.

Flow rates measured with water at 20°C at pump discharge port without accessories. Achievable flow rate in practice depends on fluid properties, application, and pump configuration.
2. MAGSON Stainless Steel
Suitale for higher pressures, higher temperatures, or where plastic materials reach their chemical limits. ATEX-certified versions are available. MAGSON MML, MMT.
| PUMP MODEL | MAX. FLOW RATE | MAX. HEAD (mWs) | PUMP DESIGN |
|---|---|---|---|
| MAGSON MML BG1 | 100 l/min | 8 mWs | Modular, single-stage, horizontal |
| MAGSON MML BG2 | 200 l/min | 11 mWs | Modular, single-stage, horizontal |
| MAGSON MML BG3 | 400 l/min | 19 mWs | Modular, single-stage, horizontal |
| MAGSON MML BG4 | 500 l/min | 24 mWs | Block construction, single-stage, horizontal |
| MAGSON MMT | On request | On request | High-temperature stainless steel — up to 300°C. Side-channel impeller. |
Stainless steel is the standard. Hastelloy and titanium are available for specific media and process conditions. ATEX certification is available on MML and MMT pump models.
— TYPICAL APPLICATIONS
Where MAGSON pumps
are specified
MAGSON magnetic drive pumps handle the fluids that sealed pumps cannot — and the applications where a seal failure is not an acceptable outcome.
MAGSON MA / MAS – PP/ETFE
Chemical Industry
Concentrated acids, alkalis, and corrosive solvents. Hermetically sealed with no shaft seal.
MAGSON MA – PP/ETFE
High-Volume Transfer
Flow rates up to 950 l/min on the MA BG7 — for high-volume chemical processes requiring sealless operation.
MAGSON MAS – SELF-PRIMING
Double-Walled Tanks
Self-priming from above the liquid level — for toxic or hazardous media in double-walled storage tanks.
MAGSON MA – PP/ETFE
Electroplating & Surface Treatment
Electroplating solutions, pickling baths, and anodising solutions. Corrosion-resistant in PP or ETFE.
MAGSON MML / MMT — ATEX
Petrochemicals
Flammable and corrosive media in hazardous areas. ATEX-certified MAGSON MML and MMT.
MAGSON MMT
High-Temperature Processes
Media up to 300°C. MAGSON MMT with stainless steel side-channel impeller for extreme temperature applications.
- mWs stands for Meter Wassersäule (German for meters of water column). It is a measurement of Lift: 1 mWs is the pressure needed to lift water vertically by 1 meter. Therefore, a pump with a max. head of 20 mWs can push water up to 20 meters high. ↩︎
