When ordering a certain type of membrane coupling, please use the following signification:
MS * */* * *.*
MS
Membrane coupling
__ *
Outer diameter D, mm
__ _ */*
Diameters of the connection holes d1/d2, mm
__ _ _/_ *
Length of coupling L, mm
__ _ _/_ _ *
Position of flanges relative to the membrane:
K external
M internal
H external for one flange, internal for the other one
__ _ _/_ _ _.*
Connection of the flanges to the shafts:
A by means of seat screws
B by means of collets
C by other means
Characteristic features:
- The flanges are external relative to the membranes
- The flanges are connected to the shafts by means of collets
- Greater length
- Ease of assembly
- Stability of the flange-shaft connection
- The flanges are internal or external relative to the membranes
- The flanges are connected to the shafts by means of seat screws
- Simple design
- Smaller length of the coupling
