Description

CRN 155-7 A-P-A-E-HQQE Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid are in high-grade stainless steel. A built-in thrust-handling device absorbs hydraulic axial forces which enables the use of a standard motor. The Grundfos cartridge shaft seal ensures high reliability, safe handling, and easy access and service. Wear parts in the shaft seal are available as service kits and can be replaced without having to renew the complete shaft seal. Power transmission is via a rigid split coupling. Pipe connection is via PJE (Victaulic®) couplings. The pump is fitted with a 3-phase, fan-cooled asynchronous motor.
