Who is Milton Roy and what does it make?
Milton Roy is an American manufacturer of metering pumps, established in 1936. The company makes piston and diaphragm metering pumps from the mRoy, Milroyal, Primeroy, Primeroyal, Proteus and Maxroy families, for precise dosing of chemicals and water treatment. From this range we can quote pumps selected according to the flow rate and working pressure required, for water treatment plants, power stations and chemical process lines.
The metal pumps in the Milton Roy portfolio reach flow rates of up to 32,980 l/h and pressures of up to 1,035 bar, depending on the model and the material of the hydraulic head. The Primeroyal family, with versions H, K, L, N, Q, R and X, covers wide flow ranges for industrial dosing, while the Proteus series (ERB, ERC) is designed for processes that need fine flow control. Milroyal D/C/B are hydraulically actuated diaphragm pumps (model D, up to 207 bar) or plunger piston pumps (models B and C, up to 689 bar), and the Maxroy series (A, B, D) completes the process pump range.
For the Romanian market, Milton Roy means access to metering pumps for water treatment plants, power stations and chemical installations, where the dosed flow must stay constant regardless of variations in back pressure in the installation.
What do we supply from the Milton Roy range?
| Product | Description |
|---|---|
| mRoy and Milroyal Metering Pumps | The mRoy series (versions XA, XB) is a hydraulically actuated diaphragm pump for chemical dosing, while the Milroyal family (D, C, B) combines a diaphragm head (model D) and a plunger piston head (models B and C), the latter for higher pressures. The choice between the two depends on the discharge pressure required and the chemical compatibility of the hydraulic head with the dosed substance. |
| Primeroy and Primeroyal Metering Pumps | Primeroy (K/PKG, L/PLG) covers smaller-scale process dosing, while the Primeroyal family, with versions H, K, L, N, Q, R, X and X FT, extends over a wide range of flow rates for continuous industrial dosing lines. Primeroyal X FT is the version with the maximum flow rate in the Primeroyal family, up to 32,980 l/h. |
| Proteus Process Pumps (ERB/ERC) | The Proteus series, with versions ERB and ERC, is a family of mechanically actuated diaphragm metering pumps. Flow rate and pressure depend on the model; we confirm them by code, from the manufacturer's documentation. |
| Maxroy Metering Pumps | The Maxroy family (A, B, D) completes the Milton Roy process pump portfolio, for industrial-scale dosing applications where a solid construction is needed for continuous operation. Selecting the right version depends on the flow rate required and on the material of the hydraulic head compatible with the dosed fluid. |
