Title: Chemical companies can reduce total cost of ownership with the right mix of metering pumps

The four most common chemical metering pump applications in chemical manufacturing plants include: • Dosing precise volumes of chemicals to make products • Pretreating the process water to boost quality and efficiency • Dosing antiscaling chemicals to clean and protect plant infrastructure • Post-treatment of the wastewater prior to disposal. Each of these applications can be addressed by reciprocating pumps, which work by using a piston or a diaphragm to dose a precise volume of fluid with each stroke. Reciprocating pumps are highly engineered to provide extreme accuracy at high pressures and relatively low flows. Rotary gear pumps provide a cost-effective alternative for some applications. They work by moving fluid in a circular fashion between gears. Rotary pumps pick up fluid at the suction port between the gear teeth, and they carry the fluid around the outer diameter of the gears to the discharge port. Rotary pumps are best utilized in high-volume, low-pressure applications, and their flow rates can be controlled with variable speed drives. Each pump type has advantages, and they both come at different price points. By incorporating the right mix of chemical metering pumps, DowDuPont, BASF and other chemical companies have been able to save money without compromising on performance.
