Drag Reducer Agents, also known as “DRA”, are chemical additives injected into liquid pipelines to increase flow throughput. With decades of experience and a field proven design, Milton Roy’s DRA pumps provide precise injection at strategic points along a pipeline network to reduce turbulence and optimize flow efficiency.
Our renowned PRIMEROYAL® and MILROYAL® series of positive displacement pumps are designed to strict API 675 standards and offer a wide range of flow rates and pressures to meet the DRA application requirements.
Milton Roy’s Global Services Network is available locally to provide customer support on any DRA application when and where you need it.
Features & Benefits
Packed plunger and PTFE diaphragm liquid end designs are available to support a wide range of DRA to meet any application requirement.
Deliver precise control with a +/- 1% steady state accuracy over 10:1 turndown ratio of the nominal flowrate in a variety of viscosities.
Modular pump design ensures the best fit and footprint for your application.
Over-pressure protection: Integrated relief valve protects the pump and environment from over-pressure conditions within the process.
Diaphragm liquid ends provide leak-proof performance with a service life up to 96,000 hours.
Discharge pressures up to 14,996 psig / 1,034 bar and flow rates to 41 GPM / 165 L/m per drive. Greater flows/pressure available upon request.
Capacity control options available for manual or remote control.
