Product Description

Product Description

(1)Features
Magnetic couplings (MAK) are a hermetic sealing solution 
for pumps and agitators. Dangerous or precious media 
remain isolated in the closed system circuit. 

(2)Advantages
• Magnetic coupling for standard applications 
• Hermetically sealed 
• No contact of torque transmitting elements 
• No maintenance necessary 
• Hastelloy® can for high performance 
• High efficient can optional 
• Product lubricated sliding bearing included

(3)Functional description
The power transmission occurs contact-free through 
magnets from the drive shaft to the product-wetted output 
shaft. Between the two rotating parts is the can wich is 
bolted to the container.

(4)Operating range (see note on page 1)

120 °C (248 °F) (NdFeB)
Speed: n = 3,600 min-1
Chemical resistance: pH 0 ... 14
Viscosity: 0.3 ... 5,000 mPas (SiC)
Torque: max. 462 Nm
Solids: max. 0.1 mm; max. 5 % by weight; 
grain hardness max: 700 HV

(5)Materials
Sliding faces: Silicon carbide SiC (Q1), Carbon silicon 
inpregnated SiC-C-Si (Q3), Carbon graphite resin 
impregnated (B)
Magnets: Samarium-Cobalt (MA3), 
Neodymium-Iron-Boron (MA8)
Metal parts: CrNiMo steel 1.4571 (G), CrNiMo steel 1.4462 (G1), Hastelloy® C-4 2.4610 (M)
