The Elongated Screws, or L Series, is designed for high volume, low pressure applications. The extended screws with large gaps allow for large solids to pass gently though the pump with little to no degradation. We can pass solids up to 67+mm in diameter—that’s a whole strawberry or a small tomato!
L Series Pumps
The elongated screw pumps have longer shafts and screws than the traditional STS Series twin screw pumps. This means mechanical seals, elastomers and the complete bearing housing all use parts in common with the standard pumps. This translates to less spare parts inventory.
In addition to higher volume displacement, the larger screw pitches give us the ability to pass extremely large solids.
