The combination of their design, which enables them to operate in extreme conditions, and their modularity makes PRIMEROYAL® dosing pumps suitable for a large number of industrial processes. Comprising 5 types of mechanism, the PRIMEROYAL® range provides accurate dosing of all types of fluids at flow rates that can reach more than 70,000 l/h. With over 50 years' experience in dosing equipment for industry, Milton Roy Europe's industrial dosing pumps provide you with Safety, Reliability and High performance.

 TYPICAL APPLICATIONS

Oil and Gas
Extraction – Process: Injection of methanol at pressures of 500 bar and more in the extraction well
FPSO – Water treatment: Injection of sodium hypochlorite, biocides, scale inhibitor, oxygen reducing agent, etc.

Refineries – process: Pumping of hydrocarbons
As hydrocarbons are highly viscous, they are heated to high temperatures so that they can be conveyed. For safety reasons (that of users, the process and the environment), double diaphragm liquid end technology is preferable. For these requirements, Milton Roy Europe provides suction and discharge valves that are separate from the pump, to avoid transferring heat to the pump.
Cooling is provided by a coolant circulating in a double jacket. This configuration can take temperatures of more than 300°C and ensures an optimum lifetime for the pump body

Chemical and Petrochemical industries

Process: Dosing catalysts for polymerization of polyethylene

Process: Injection of supercritical CO2. Two possible solutions: metal liquid end with metal diaphragm or metal liquid end with PTFE diaphragm equipped with a system combining continuous degassing and diaphragm rupture detection (Milton Roy Europe patent)
