Best Value - standard combination tungsten carbide and silicon carbide seal configuration generates less heat, promotes longer seal life and is a leader in durability. The ZP3 positive displacement pump series offers the most features with tremendous maintenance savings, all at an affordable price.

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.

The ZP3 positive displacement pump series with its internal seal design is a smart choice for this application providing the most features and tremendous maintenance advantages, contact Ampco’s Technical Sales Team today to discuss your specific application needs.
