Product details

The manufacturer describes large impeller passages for solids of 5–125 mm, depending on the selected pump. This is a range across the family, not a 125 mm guarantee for every frame. Applications include municipal sewage, rainwater, industrial or agricultural wastewater and raw-water transfer. Corrosive duties require an appropriate special material selection.

Installation choices include a fixed wet-well arrangement with guide rails and an automatic coupling, a fixed dry arrangement, and mobile deployment. A cooling jacket supports the dry or exposed-motor arrangement described in the catalog, but the manufacturer specifically excludes pumps below 15 kW from that cooling-system provision. Dry operation must therefore be confirmed for the actual model.

The catalog describes overload, leakage, temperature, moisture and water-ingress monitoring, together with level control. High-temperature wear-resistant and explosion-protected pumps appear separately in the appendices. Their different operating limits are not applied to the standard QW family on this page.

SELECTION NOTES

Specify the operating duty

State the required flow and head, solids size and volume fraction, liquid chemistry, pit depth, installation method, cable length and control requirements. Confirm cooling provisions before choosing a fixed dry arrangement.

Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
