NUCLEAR GRADE RESINS

Gravex® is a complete product line of high-purity, quality-certified cation, anion and mixed bed ion exchange resins.

These custom-blended bead resins are the cleanest bead available, washed and classified, every batch tested and samples filed for future reference.

They are processed to meet nuclear specifications. We offer the most conclusive results available for nuclide removal products. Graver Technologies also supplies bead resin manufactured by Dow, Rohm & Haas and Lanxess (Bayer).

These Gravex Nuclear Grade Ion exchange resins are very high capacity polystyrene, gel type resins. They have been regenerated and processed to provide the highest possible performance in nuclear applications. The Gravex cation is specially processed to minimize leachable sulfonic acids.

Its high capacity and oxidative stability help achieve optimal performance. Gravex mixed beds are the most uniformly blended products available and have the same consistent cation to anion ratio in every package. Our unique blending process creates the less separable GR-3-16 NG stoichiometric mixed bed. A 7Li+ form cation is available as GR-7-16 NG and in the GR-4-7 NG mixed bed.

PRISMA Dosing Pump

PRISMA dosing pumps: the incomparable accuracy of the stepper motor – EMEC.

EMEC is proud to introduce the new stepper motor-driven dosing pump PRISMA, the best solution for offering high-accuracy metering and extreme reliability.

Thanks to the new stepper motor and to the MultiFunction software, PRISMA dosing pumps offer complete control over dosing speeds and working modes as well as great flexibility and repeatability, meeting even particularly complex application needs.

PRISMA is also equipped with Level control, Alarms and Stand-by, while available working modes include Constant, Constant with external input, ppm, %, mlq, Pause-work, Weekly, mA, Pulse, Volt, external Batch and manual Batch.

PRISMA dosing pumps feature the Encoder control knob for quickly browsing through the configuration menus. And a large display to easily control and regulate the working parameters. By changing background colors PRISMA backlight display is capable of signaling different working status: pump running (green); stand-by (white); warning condition (yellow); alarm condition (red).

TURNDOWN

PRISMA stepper motor-driven pumps give you the most accurate control over the stroke speed, providing an outstanding turndown ratio of up to 4800:1.

It means PRISMA, through its digital multifunction control, can split up the dosing process into a maximum of 4800 steps in order to offer the most homogeneous and precise distribution of the product to dose according to the required application.

SLOW MODE

The extreme versatility of PRISMA dosing pumps is also due to Slow Mode function. With Slow Mode enabled you can reduce the suction speed to 75, 50 or 25% of the normal speed, making easier, more reliable and extremely accurate the priming and the dosing, even when you have to handle particularly viscous liquids.

CAPACITY RANGE

PRISMA stepper motor-driven pumps are available with dosing capacity of 5, 13, 28 and 80 l/h at a working pressure of 20, 10, 5 and 2 bar, respectively.
