Key Features
  • Combining the High Flow Slimline Style One Nut diaphragm pump with our barrel emptying system, enables you to now pump highly viscous materials out of your barrel at increased flow rates.
  • System can be cleaned in place using the pump itself or an external CIP rig.
  • Can be easily stripped down for cleaning due to the One Nut design of the pump.
  • Minimal wastage is achieved with our inflatable seal which ensures the minimum of product is retained in the barrel.
  • Less product hold up than other systems.
