VERTIFLOW F 728 Submersible Centrifugal Pump

Stationary circulation and filter pump for flow rates up to 750 l/min and extreme operating conditions.

The VERTIFLOW F 728 submersible centrifugal pump conveys and circulates chemically aggressive liquids in stationary systems. It is suitable for applications in the chemical industry, process engineering, surface technology, water treatment, and wastewater post-treatment.

The series features a modular design and can be adapted to various installation scenarios. Up to an immersion depth of 600 mm, the pump operates without bearings in the fluid zone and is protected against dry running. With slide bearings, immersion depths of up to 1,800 mm are possible.

The spiral casing supports high flow rates with low energy consumption. This makes the F 728 suitable for demanding circulation and filtration processes.
