With up to 500 horsepower and 1,695 lb-ft torque, the Cummins X12 is ideal for septic and sewer vacuum trucks. It provides a high power-to-weight ratio and is also the lightest engine in its class, weighing 400 to 600 pounds less than other engines.
The lightweight and durable X12 carries more liquid waste without sacrificing throttle response for frequent stop-and-go duty cycles. A new Cummins engine brake also strengthens stopping power over the ISX12, lengthening service brake life. It is fully PTO capable and, through Connected Diagnostics, X12-powered trucks can be wirelessly connected to Cummins product experts for immediate diagnosis of engine system faults.
