What makes our Twin Diaphragm Pumps different?

TT Twin Pumps (HDPE & PTFE) may be fitted with multiple porting configurations to achieve up to 2 pumps in 1 for blending, mixing or recirculation applications and therefore simplifying pipework configurations and the system in general! In the example shown, the TT Twin HDPE/PTFE Pump is fitted with twin inlet and outlet ports. Effectively enabling 2 pumps in one.
