Dosing pumps

Milroyal^® D: HIGH-PERFORMANCE DOSING

MILROYAL^® D pumps were specifically developed to produce micro flow rates at medium and very high pressures.
Their flow rate/pressure performance, ranging from 0.11 l/h to 345 l/h / 500 bar, means that they can be used for numerous applications with dosing accuracy of ±1%.

MILROYAL^® D pumps are particularly rugged and can operate in the severest of conditions, such as on offshore platforms, in the desert, etc., and the oil bath gives moving parts an exceptionally long service life.

TYPICAL APPLICATIONS

Oil and Gas
Extraction: Well-head or pipeline corrosion inhibitor injection, chemical injection for odorisation of gas before transport

Industry
Boiler water treatment: Injection of oxygen scavenger, scale inhibitor, biocide, corrosion inhibitor

Energy
Water treatment in utilities: Injection of corrosion inhibitor (phosphate), hydrazine, ammonia

Our main customers
Aramco, Borouge, Qatargas, Sabic, Saudi Electricity, Saudi Polymers, Sonatrac
