Fixed Speed / Constant Fill Fluid Couplings
SM & HF
Shaft Mounted SM/SMD/SM-DX
These are shaft mounted coupling
enabling axially compact drive space.
Rubber coupling on one end.
Radially Displaceable HF /HFD /HF-DX
These are radially displaceable coupling enabling
prealignment of driving and driven shafts. Metallic
disc flexible coupling on both ends. Weight of
coupling shared by driving and driven shafts.
Fixed Speed / Constant Fill Fluid Couplings
· To satisfy starting and running characteristics of industrial machines Fluidomat offer three circuit types to give starting
torque down to 120% of nominal torque.
· Type SM and HF are basic coupling without delayfil chamber. Starting torque adjustable in the range of 170% to 270%.
· Type SMD and HFD are couplings with delayfil chamber. Starting torque adjustable in the range of 140% to 270%.
· Type SM-DX and HF-DX are couplings with extended delayfil chamber. Starting torque adjustable in the range of 120% to
270%.
· Normal operating slip - 2% to 5% depending on coupling size and starting torque value.
· Fusible plug blow off temperature 130°C as standard. Optional 160°C.
· Suitable for two consecutive starts from hot and three from cold.

Coupling types SM/SMD/SM-DX are supplied in
finished bores on the fluid coupling shaft. However
where it is not possible to specify finished bores at
the time of ordering, we can provide a seperate shaft
bush with OD> Ød4 and * narrow keyway. The
allowable maximum bore in the shaft bush is denoted
by Ød5 shown in the dimension table.
