Continuous and Precise Volumetric Dispensing

Nordson EFD has introduced the 797PCP family of pumps and controllers, which provide controlled, continuous volumetric metering of single and two-component fluids, unaffected by external factors such as changes in viscosity or pressure. Process control is very advanced as the minimum deviation
is ±1% and the fluid devices are repeatable by only 0.01 ml per revolution.

Nordson EFD has released new volumetric progressive cavity pump systems that include 797PCP and 797PCP-2K pumps, and 7197PCP-DIN or ValveMate 7197PCP controllers. These new volumetric dispensing solutions deliver precise, repeatable fluid volumes as small as 0.01 ml per revolution.
Deposit volume tolerances equal to ±1% allow for a high level of process control in automotive, electronics, medical, and other production applications.
These systems, therefore, make possible the controlled and continuous volumetric dosing of mono and bi-component fluids.

Exact adjustment of dosing parameters

The design of the 797PCP is based on the progressive cavity principal where its core components, a rotor and stator, form a perfectly sealed metering chamber. As it rotates, the pump allows continuous volumetric dispensing that is unaffected by external factors such as changes in viscosity, fluctuating fluid pressure, and the full-to-empty effect in syringe barrels. This continuous seal also prevents shear and pulsation, making the 797PCP ideal for precise dispensing of abrasive pastes, epoxies, and UV-cure adhesives. The pumps come in three sizes: 0.01 ml, 0.05 ml, and 0.15 ml.
The 797PCP-2K pump provides highly accurate meter mix dispensing of two-part assembly fluids. Its modular design allows for multiple mix ratios. Its compatibility with a wide range of disposable EFD bayonet static mixers simplifies implementation. Both the standard and 2K pumps work best when controlled by either 7197PCP-DIN or ValveMate 7197PCP controllers. These controllers allow for precise adjustment of dispensing parameters. The DIN rail version offers an intuitive web-based interface. The ValveMate version offers an intuitive touchscreen interface. Both provide multiple programming modes, including Line, Volume, Weight, and Timed, to meet a wide range of application requirements.
