Maintaining the same size footprint of previous models, the sleek new pump offers a number of product enhancements to provide longer life and product convenience, while the physical design signifies supreme quality. The newly redesigned housing improves the drives heat transfer properties, as it generates heat farther away from the electronic components to maintain the long-term integrity of the PC Board. Electrical connector attachments have been repositioned to the front of the pump for easy access. With a new clear cover the face of the pump is shielded from exposure to corrosive substances yet lifts easily for convenient access, allowing operators to view dial settings for fine-tuning output. In addition, the pump and liquid end mounting geometries have been improved for enhanced connections. For more information please contact LMI Milton Roy

High discharge accuracy
The main components such as the plunger and cylinder are processed with high precision of micron order, so it is possible to obtain high discharge accuracy. (Discharge accuracy : }0.5%) By changing the angle of the pump head it is possible to freely adjust the discharge amount between 0 and maximum discharge.
Excellent corrosion resistance
Materials such as silicon carbide (SiC), fluorocarbon polymers (PTFE) and stainless casting (SCS14) with excellent resistance to corrosion are used for parts that come in contact with the fluid. This makes it possible to use the pumps for handling a wide range of chemicals.
Dispense into a vacuum condition and removal from a high-pressure condition
Since there are no suction and discharge valves, it is possible to directly dispense a constant amount of fluid in a vacuum (negative pressure) without using a solenoid. Constant-volume dispensing is also possible if suction side is pressurized.
Capable of handling slurries and highly viscous fluids
The unique valveless construction and the excellent resistance to wear of SiC, it is possible to handle slurries with fast precipitation speed as well as abrasive slurries. Also, the pumps are capable of smoothly pumping highly viscous fluids up to a maximum viscosity of 20,000 mPas.
Note: The discharge accuracy drops for viscous fluids with a viscosity of 500 mPas or greater. Contact this company for details.

Economical and robust, the Milroyal G pumps dose all traditional liquids used in water treatment and industrial processes including: acids, bases, chlorinated products, coagulants, and other products. Designed for ease of maintenance and start-up, the Milroyal G features a robust HPD-style hydraulically actuated diaphragm liquid end coupled to a variable eccentric drive. The absence of contour plates in this liquid end results in "straight-thru" flow ideal for handling polymers and slurries. A unique integral 3-function valve allows for purging of any entrapped gases in the hydraulic oil without disturbing the relief valve setting. Also integral to the liquid end is a site glass for visual indication of a relief condition in the hydraulic system. The smooth sinusoidal flow produced by the variable eccentric drive minimizes flow pulsations and mechanical shock to system components.
Product Features:
HPD liquid end design eliminates contour plates.
Double diaphragm w/leak detection available (10/98).
Liquid End Materials: PVC, PVDF, 316SS.
