Slurry Pumping Handbook AU
Slurry Pumping Handbook – AU Page 6 Issued: Feb 2000 The centrifugal slurry pump must be designed to allow the passage of abrasive particles which can at time be extremely large. The largest slurry pump, for example, can pump particles up to 530mm in spherical size. Slurry pumps therefore need much wider and heavier impellers to ...
