MYERS SR1830 & CMV1830 are submersible sewage pumps designed for efficient and reliable operation in sewage basins. These pumps feature a pre-set fluid level control, allowing for automatic or manual operation. The oil-filled motor ensures efficient operation, while the included full-flow check valve eliminates back-flow and reduces vibration. The pumps are designed for simple and quick installation, with a standard 18" x 30" sewage basin in mind. They come equipped with a float switch and a power cord for easy connection to a properly grounded electrical outlet.
