MILTON ROY

Milton Roy

Milton Roy is the world’s leading manufacturer of controlled-volume metering pumps that set the industry standard for performance, accuracy and durability.

G Series Macroy® / Milton Roy, Series G

Series G™ dosing pumps are electric motor-driven pumps with mechanical diaphragm liquid ends. Simple, economical and rugged, they offer great flexibility and a wide selection of liquid ends compatible with most chemicals. With a corrosion-resistant plastic or aluminium housing, depending on the model, they are based on two technologies previously only used for intensive-use industrial pumps: variable eccentric drive and stroke adjustment. Series G™ is made up of three dosing pump models, covering a very wide flow range (up to 1,200 l/h) at an excellent quality-price ratio.

Benefits

Versatile: dosing of all known reagents

Continuous 24-hour operation

Wide flow range

Dry running without damage to the pump

Set flow rate accurate to within ± 2% over the range from 10 to 100% to meet the exact needs of your process

Automatic flow control

Proportional control via automatic flow adjustment (VARIPULSE® options)

Minimal pulsing and no water hammer (low output pulse) protects pipes

Few moving parts for long service life and reduced heating

Light, compact pumps for a small footprint and ease of handling

Minimal maintenance with pumps lubricated for life

Centrac™ Series

Centrac pumps combine a unique constant stroke length drive mechanism and electronic variable speed drive technology. The unique drive system provides a steady state accuracy of +/- 0.5% over the entire turndown range. This is twice the accuracy of the standard +/- 1% of most metering pumps. Greater accuracy means better control of the treatment process and more efficient chemical usage. In addition, these pumps offer a 100:1 turndown ratio. The advanced design enables the pumps to respond instantly to changes in dosage rate, making it the ideal metering pump for a wide range of flow rates in water and wastewater treatment applications.

Top-Entry Mixers

Mlton Roy Helisem Mixing Range

The HELISEM range, with 250 standard models, is designed for economic mixing solutions. Mixing is often at the heart of your process and optimised mixing can provide you with

Savings From Several Aspects:

Shorter treatment times > Less heating, etc. required.
Fewer deposits > Less waste to be treated
A better quality product > Higher added value
A higher reaction efficiency > Fewer by-products
Lower power consumption > Lower electricity consumption and better protection of the environment
Reduced maintenance due to simple, reliable design > Lower maintenance costs in terms of parts and labour

Custom-Engineered Side-Entry Mixer

Our side-entry mixer is mounted quickly and easily to the tank flange and delivers the most effective blending results in an extremely efficient unit. Our innovative small diameter SABRE® impeller allows for reduced energy consumption and easy installation.
In addition, we can ensure proper agitation using numerical simulation of fluid flows (CFD). This helps to forecast and predict the storage tanks mixing with no dead zone, and lower energy consumption compared to conventional solutions. We can also provide an adjustable agitator to increase the scope enclosure.
The side-entry mixer concept is driven by four top priorities: safety, reliability, process optimization and easy, cost-effective maintenance.

Large Mixing Volumes
The mixer is designed for tanks up to 200,000 m³ (1.3 MM barrels). The high liquid jet amplitude propelled by our impeller allows the moving of large volumes using less power.

Easy Installation and Maintenance
This compact, side-entry mixer has been designed specifically to mount on the lateral flange of the tank and with lightweight, custom impellers, it can installed quickly and easily. Its exclusive seal shut off device allows for safe, fast and easy maintenance or replacement of the mechanical seal without emptying the tank.

Low Power Consumption
Our innovative, proven SABRE impeller uses less energy to effectively mix the tank contents.
