Selecting a pump or replacement parts
Check rated flow, pressure, rotational speed, inlet temperature and drive arrangement against the intended duty. Similar-looking pumps can have different shafts, mounting dimensions and seal specifications. The complete model code and parts diagram are therefore essential when ordering service kits or replacing an existing unit.
