Grundfos CR 10-3 Vertical multistage pump
Vertical, multistage centrifugal pump with inlet and outlet
ports on same the level (inline). The pump head and baseare in cast iron – all
other wetted parts are in stainless steel. A cartridge shaft seal ensures high
reliability, safehandling, and easy access and service. Power transmission is
via a rigid split coupling. Pipe connection is viacombined DIN-JIS flanges.
The pump is fitted with a 3-phase, fan-cooled asynchronous
motor.
