Comparison of used impeller / new impeller
Cutting the budget by three
Thanks to Metso’s option of several sealing systems, pump casing linings and impellers, it is possible to configure a pump to the precise needs and optimize the process. This allows a pump to be adapted to any process changes.
For this case, a Metso HM150 double-adjustment pump was installed and optimized for the correct sand concentration, the maintenance needs of the operation dropped drastically. This was a rubber-lined pump with a high chrome metal impeller and a clear water pressure injection seal.
As Eric Viale says, “After the reconfiguration, Anthony regularly monitored the wear of the parts and trained us to adjust the pump. We quickly saw that the life of the parts was three times longer than those of our old pumps. As a result, we stop much less frequently than before to change the wear parts, thanks to the optimization of their service life, which has enabled us to reduce the pump’s operating budget by a factor of three.”
He goes on to say that maintenance time on the pump during parts replacement is quick and easy, due to the impeller release mechanism that rapidly allows uncoupling. The system is also very safe during maintenance operations.
“Added to all this, we also have the follow-up that we wanted from our after-sales technician, who continuously provides us with new solutions and trains our staff,” Viale concludes with satisfaction.
