Grundfos - CRNE1-23 Q-P-T-E-HQQE Vertical Multi-Stage Pump - 400V - Three Phase - 58 Ltr/min. - Stainless Steel

Vertical, non-self-priming, high-pressure multi-stage centrifugal pump unit with suction and discharge ports on the same level (in-line) enabling installation in a horizontal one-pipe assembly. The chamber stack is turned upside-down to ensure that the shaft seal is not affected by the high pump discharge pressure. Pump materials in contact with the liquid are in high-grade Stainless Steel. A cartridge shaft seal ensures high reliability, safe handling and straightforward service and access. Power transmission is via a split coupling. Pipe connection is via PJE (Victaulic®) couplings. The pump is equipped with a 3-phase, fan-cooled, permanent-magnet, synchronous motor. The motor includes a frequency converter and PI controller in the motor terminal box. This enables continuously variable control of the motor speed, which again enables adaptation of the performance to a given requirement.
