New Fusion Dampeners from Griffco Valve combine the technologies of the company’s back pressure valves and pulsation dampeners into one product in order to simplify a chemical-feed system installation. They feature large internal passages so that there are no restrictions on flow rate or pumped fluid cleanliness. The combination of these two devices into one accessory will also reduce the number of joints, hence fewer leak path opportunities, and provide for a smooth, nearly pulseless chemical-feed system.
