Front Loading Seal LF Series is a Maintenance Dept Favorite

Ampco’s LF is designed with a unique front loading seal for maintenance ease and improved clean-ability.

While seal designs in competitor pumps are known to leak due to product build-up when processing tacky or sticky products, the specially designed Ampco LF seal eliminates this problem area by removing the traditional O-ring groove and dead zone. The innovative design of the Ampco LF seal offers a semi-exposed O-ring allowing product to flow freely through previously restricted areas eliminating product build-up.

The LF seal design offers ease of assembly. Exclusive to the Ampco LF, the rotating seal stays retained in the driver during the assembly process too.

Balanced impellers, a self-aligning shaft design and tight manufacturing tolerances, minimize vibration and improve seal life, making the LF a preferred choice for difficult to handle products.

Cryogenic Low Temp Applications. 

CBD hemp oil or Cannabidiol is fast becoming a mainstream ingredient for beverages, health products, gels, and other consumables products. The extraction process of these valuable oils can require pumping ethanol at temperatures as low as -70F (-56C).  Ampco has designed a special seal for positive displacement and centrifugal pumps that are suitable for these extremely low temperatures.
