The front loading seal can be changed simply by removing the front cover and impeller.

Ampco’s metric LM Series centrifugal pumps are designed with a unique front-loading seal similar to the LF Series US measurement version. The front-loading seal design excels at ease of maintenance and improved cleanability.

Seal designs in competitor pumps have been known to leak due to product build-up when processing sticky products, the Ampco front-loading seal design eliminates this problem by removing the O-ring groove and dead zone. The unique design of the Ampco LM seal offers a semi-exposed O-ring allowing the product to flow freely through those traditionally restricted areas solving the product build-up dilemma.

The Ampco LM, rotating seal stays in place inside the driver during the assembly process. This design also facilitates ease of assembly.

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

The LM Series is a highly efficient centrifugal pump that handles product gently while providing a more sanitary seal design than competing pumps.

Industry-leading delivery times, 304 stainless steel adaptors, seal design advantages, and a maintenance-friendly assembly process makes Ampco’s LM Series the right choice.

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.
