In 1998, industrial users demanded a robust, reliable mechanical diaphragm pump that combined the precision of metering technology with the ease of use of Air-Operated Diaphragm Pumps (AODD). While AODD pumps offered a lower upfront cost and ease of maintenance, they lacked the accuracy needed for critical applications. And lets not forget, costly compressed air.

Enter Blackline. Engineered as a cost-effective alternative to AODD pumps, the Blackline M Series was designed to deliver metering precision, reliability, and efficiency. Today, with over 1,000,000 pumps in operation, Blackline is the preferred choice for demanding industries that require accuracy, durability, and performance in every application.
