BSTM Flexible Impeller Pump
BSTM’s stainless steel pumps, featuring a flexible impeller design suitable for food contact, are designed for the safe transfer of sensitive products such as olive oil. The high shear forces generated by pumps with metal impellers can lead to aroma loss and quality defects in olive oil. The flexible impeller design, however, operates at lower speeds to provide a gentle and controlled transfer without damaging the product’s structure.
The pump operates effortlessly even when the line is empty, thanks to its strong suction capability. In filtration applications, its adjustable design—which adapts to the desired pressure—helps prevent excessive pressure buildup even if filter clogging increases; this reduces the risk of filter rupture and contributes to system protection.
Since the flexible impeller can operate in both directions, there is no need to reconfigure the pump connections when changing the flow direction. This provides significant operational convenience during use.
Advantages and Benefits
- The flexible impeller design helps preserve the aroma and natural structure of olive oil by reducing high shear forces.
- The adjustable pressure system reduces the risk of excessive pressure even if filter clogging increases, thereby helping to protect the filters.
- The ability of the pump impeller to operate in both directions allows for practical use without changing the connection layout during flow direction changes.
- The stainless steel housing and appropriate pump design ensure compatibility with hygienic production lines.
