Nordson EFD volumetric progressive cavity pump systems include 797PCP and797PCP-2K pumps, and 7197PCP-DIN or ValveMate 7197PCP controllers.
These 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.
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.
Combined with the NX functionality, the 7197PCP-DIN-NX controller allows operators to control all volumetric dispensing parameters directly from a Programmable Logic Controller (PLC) or other manufacturing plant controller.
