INSTALLATION
3.1
MOUNTING/FASTENING
The pump should be mounted and fastened on a solid base plate with a flat and horizontal surface
to avoid distortion. The pump must be mounted in such a way that the shaft centerline is horizontal.
When mounting a V-belt pulley on the pump a bore H7 is recommended. To facilitate the mounting
the hub in the V-belt pulley may be heated to about 100ºC after which the V-belt pulley is easily
lead over the shaft towards the shoulder. Alternatively, the V-belt pulley may be mounted with a
TAPER LOCK bush.
