SAMOA: DirectFlo® Pumps

A fresh take on diaphragm technology

Directflo® pumps are designed around an inverse idea to the common solution for a diaphragm pump unit. With SAMOA DirectFlo products your fluid moves through the central part of the pump, most commonly used for the air motor assembly with other manufacturers, whilst the compressed air is powering the diaphragm movement from the external faces and pump chambers.
