WQCS/WQD-Q Series Sewage Grinder Submersible Pump
The WQCS/WQD-Q series of submersible sewage grinder pumps are specifically designed with an integrated grinding system that efficiently breaks down solid waste into smaller particles, allowing for easy passage through pipes with a relatively small diameter. This makes them ideal for applications where the removal of large debris is required.
**Applications and Installation**
These pumps are suitable for domestic, commercial, and industrial use. They can be used to handle wastewater from water closets, as well as sewage from restaurants, hotels, camping sites, and similar locations. The compact design allows for both temporary and permanent installations. The pump can be mounted on an auto-coupling system or placed directly on the bottom of the sump pit. The WQCS model features an open impeller, which enhances its ability to handle fibrous materials.
