Proporción fija Hydra-Cat  Dosificador mecánico

El diseño de bases de bomba múltiples proporciona materiales de dos componentes con precisión

Dónde comprarSolicitar información

Los dosificadores de proporción fija Hydra-Cat bombean con precisión materiales de componentes plurales mediante el uso de dos o tres bombas de desplazamiento positivo con un motor de aire común. Esto asegura que el promedio del recorrido y el largo del recorrido de todas las bases de la bomba sean idénticos, proporcionando un suministro constante.

Los modelos con dos bases del mismo tamaño proporcionan fuerzas de bombeo balanceadas que evitan el desgaste prematuro del prensaestopas. Los modelos con tres bases y cilindros de varios tamaños se pueden seleccionar para proporcionar una amplia variedad de proporciones de mezcla.

  • Bases de uso intensivo para resistir el desgaste y lograr durabilidad
  • Las configuraciones de bases de bomba múltiples alcanzan una amplia variedad de proporciones de mezcla
  • Dos bases de bomba ofrecen una proporción de mezcla constante de 1:1
  • Tres bases de bomba ofrecen una proporción de mezcla superior a 1:1 para un bombeo balanceado
  • Los prensaestopas PTFE son estándares en las bases de Hydra-Cat

Air consumption example
When the air pressure to the pump is 60 psi (410 kPa, 4.1 bar) and you are dispensing 1 gal. (3.8 liter) of mixed fluid per minute, air volume used, in cfm, will be about the same as the larger pressure ratio figure of your pump. See instruction manual for pressure ratios of pumps. Xper minute, air volume used, in cfm, will be about the same as the larger pressure ratio figure of your pump. See instruction manual for pressure ratios of pumps.
