Product Description

WQ Cast Iron Sewage Pump

Restrictions on use

• Maximum burial depth: 40m

• Liquid temperature up to + 40°C

• Ambient temperature up to + 40°C

Purpose and installation

The pump uses double-sided vortex impellers designed to lift dirty water that is not chemically aggressive to the pump components. Recommended applications therefore include drainage in confined areas such as basements and garages, as well as domestic waste pumping and the treatment of wastewater containing fibers, which are also widely used in many factories. These pumps are easy to install and reliable for automated use in hybrid applications. Installing a suitable check valve in the pipeline prevents backflow when the pump stops.
