Flygt Launches Clog-free High-head Pumps

01.02.2005

In 1999 ITT Flygt introduced the N-pumps for efficient, reliable wastewater pumping. Now the product range was extended by new pumps with the same self-cleaning N-technology, 3153 and 3171, suitable for low-flow, high-head situations.

Conventional pumps with a channel impeller gradually lose efficiency and consume more power as the impeller becomes clogged. In this case, pumping efficiency is restored when the pump is cleaned by back flushing during shut down.

The self-cleaning, clog-free N-pump solves the problem. Its unique, semi-open impeller, combined with a relief groove in the volute, has been proven to reduce the risk of clogging and maintain pumping efficiency, even under the worst conditions.

This patented combination provides a self-cleaning flow path through the pump, greatly reducing the risk of clogging and making the N-pump series an ideal solution for high-efficiency pumping over long duty periods. The result is lower overall energy consumption, which reduces the lifetime cost of a pumping operation.

Flygt’s new super high-head pumps 3153 and 3171 have a maximum discharge head of about 90 meters (or 300 ft). They provide optimal performance for applications with a high head and low flows. Clients who opt for a super high-head pump can choose a smaller pump, too, which means lower installation costs and reduced energy consumption.

These solutions are already in service at pumping stations around the world. Flygt recently sold the 10,000th 3153 pump, and continues to expand its offering of N-pumps for an ever-wider range of applications.
