of wearable parts
4. Closed impeller with back and front impeller
vanes to relieve the pressure at the stuffing box and inlet,
limiting leakage
5. The Marlin Pump can be fitted to different
bearing housings so that the hydro dynamic requirements can be
matched to the specific bearing loading, resulting in a price
advantage
6. The stuffing box is detachable and has a
split gland which permits ample space for easy replacement of the
packaging rings
