Pneumatic Chemical Metering Pumps, Single shot intensifiers, injection plungers, often used for corrosion inhibiter, and methanol on hydrocarbon production platforms in conjunction with pulsation dampener designs. Plunger type fluid driven pumps tend to have a fast suction stroke which then causes a discharge shock pulsation, to ensure fast filling a Pulsation-Dampener is used on the supply side of the pump. Pulsation-Dampener designs for Pneumatic Chemical Metering Pumps are available from inventory /stock at 6K 11K & 15K psi, in PTFE + 316L, Duplex & Super Duplex Stainless Steels from PulseGuard Ltd.
