DWC

DWC - Single and twin impeller centrifugal pumps

Centrifugal pump fitted with a closed radial flow impeller in AISI 304 stainless steel. It is equipped with an insulating shell as standard, which prevents condensation inside the system. It is available with special seals for heavier duty use and higher liquid temperature limits. The choice of connections, Victaulic (DWC-V) and threaded (DWC-N), facilitates installation. Read more

Centrifugal pump fitted with a closed radial flow impeller in AISI 304 stainless steel.
It is sturdily built, made using the exclusive hydroforming process, and is equipped with increased discharge due to the absence of additional fittings.
It is equipped with an insulating shell as standard, which prevents condensation inside the system, and the standard mechanical seal is in Ceramic/Carbon/EPDM. The DWC centrifugal pump is available with special seals for heavier duty and higher liquid temperature limits.
The choice of connections, Victaulic (DWC-V) and threaded (DWC-N), facilitates installation.
