ULTRA-FLO Metal Series

The ULTRA-FLO Series Metal Air-Operated Diaphragm Pump is an innovative and affordable series catered for the ever-growing industry. This product available in Stainless Steel (SUS316), Cast Iron and Aluminium.

Stainless Steel (SUS316) offers superior resistance against corrosion by chlorides and acids at high temperature. On the other hand, Aluminium offers malleability, recyclability, resilience against fire, rust-resistant, and higher strength to weight ratio; thus making it highly durable in extreme environment. Cast Iron is suitable for general purpose pumps. It has good corrosion resistance to neutral and alkaline (high pH) liquids.
