MILTON ROY, Milroyal D
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.

Micro flow rates and high pressure

· Dosing from 0.11 l/h
· Maximum pressure: 500 bar
· Half a century of experience in micrometric flow rates

Unrivalled design
· API 675-compliant
· Exceptional moving part service life (oil bath)
· Diaphragm dosing pumps:
~Integrated safety valve protects the pump fully against any overpressure
~ Double or Triple diaphragm options ensure high levels of safety for users, the process and the environment
· Operation in the severest of conditions for instance when integrated in a chemical injection package
