SERIES 6100 PUMP CONNECTORS
Stainless steel flow liner are
optional on all models. Recommended
for severe turbulent flow.
Restrained models are designed
to protect the connector from
overtravel and to react the thrust
loads due to internal pressure
All components are joined by
inert gas fusion welding. the
contact surface is entirely in
stainless steel.
Flanges are carbon steel / RSt 37.2
The dimensions and drilling
conforms to DIN - 2501 /
