One simple and efficient solution is to inject chemicals into the processes, in order to increase the production capacity, inhibit deposits, reduce the corrosion, and to make the process more reliable. These chemical injection systems are largely used in the O&G production sites to prevent and mitigate some problems that might negatively impact the process.
Milton Roy offers a wide range of pumps with a large choice of equipment and material options which could be configured for any chemical injection application.
Milton Roy API 675 pumps are the most advanced metering pumps dedicated to chemical injection systems/packages, because of the flexible modular drive design combined with the packed plunger or the high performance diaphragm liquid ends. The modular design enables multiplexing and customizable configurations in order to maximize the performance in a small footprint.
Some chemical fluids, like methanol require a leak proof design because the methanol fluid is volatile and dangerous for people and the environment. Milton Roy recommends the use of double diaphragms combined with a diaphragm rupture detection system to optimize the safety of this critical application.
The PTFE or metallic double diaphragm is designed to inject continuously or intermittently the methanol at high discharge pressure, up to 1034 bar (15.000 psi) in standard, and 1379 bar (20.000 psi) on demand.
Milton Roy designed innovative features to improve the efficiency of chemical metering pumps, such as the patented DSD technology (Dynamic Stiffness Diaphragm) which is used for dosing viscous chemical products, at low flow rates and high discharge pressures.
The patented internal MARS pilot valve (Mechanically Actuated Refill System) combined with the internal pressure relief valve is a proven technology to increase the reliability of the pump, in case of unexpected running conditions and to prolong its lifetime.
The innovative variable eccentric drive combined with proven experience in metering pump technology gives the highest reliability in most chemical dosing processes with high repeatable accuracy. This variable eccentric drive design gives flexibility of production, by modulating the flow rates during the operation.
Milton Roy metering pumps have been used in hundreds of installations worldwide with one of the best reliability track records.
