The PT Coupling 140400 is a chemical-duty Flow Control pumping system built around a gear pump sized to accommodate 3-inch Blackmer pumps. Like PT Coupling's other Flow Control Systems, it mounts to the side of a truck or trailer and is driven off the truck's PTO, either through a driveline or hydraulically, with a secure valve arrangement that lets the driver stay off the tank top while loading and unloading chemical product.
