Large-displacement milliliter dispensing.


High-Capacity eVmP Pump
The VS10-Series is a Zaxis eVmP valveless metering pump for milliliter-scale dispensing and continuous metering. Its V6SAN-W milliliter head combines a large fill volume with a valve-less piston design, while the VMP-OEM-VS10 servo-driven drive supplies the speed and control needed for demanding high-flow dispensing applications.
The VS10-Series dispenses 6 L/min at 600 RPM and can dispense nearly 10 mL per stroke. The V6SAN-W head is paired with the VMP-OEM-VS10 drive, which operates at up to 600 RPM depending on viscosity. This combination suits applications that require substantial volume per cycle without moving away from controlled positive-displacement metering.
Fluid-contact materials for the V6SAN-W include medical-grade alumina-oxide ceramic and 316 stainless steel, with customization available. The pump head also uses 316 stainless steel and PTFE wetted parts and can be supplied with tri-clamp or sanitary fittings, optional wash glands, and numerous fitting configurations for application-specific fluid paths.
The VMP-OEM-VS10 supports continuous metering, single or multiple dispense, flow dispense, flow direction and suck-back operating types. It stores up to 50 programs and provides RS485 in half- or full-duplex modes with optional EtherNet/IP. Zaxis has made electronic metering pumps for more than 25 years for automation production lines that require repeatable fluid handling.
Request for QuoteThe VS10-Series brings a large-displacement milliliter pump head and a specialty servo drive together for applications where output volume, speed and controlled operation all matter. The V6SAN-W head offers one of the largest fill volumes per stroke and metering rates in the Zaxis milliliter range, while the VMP-OEM-VS10 accepts the head as a complete pump system.
A valve-less piston design avoids external supply and discharge valves. The V6SAN-W uses ceramic, 316 stainless steel and PTFE in its wetted path, and its optional sanitary details help configure a fluid path for the process at hand. The head is rated for -20˚C to 70˚C, non-condensing operation, supporting a broad operating environment across configured production setups. On the drive side, the servo platform makes it possible to select continuous, dispense and flow-oriented operating modes from one controller.

The VS10-Series is built around a milliliter head and servo-driven system intended for high-capacity liquid handling. Its material options, configurable fittings, stored programs and industrial communications provide a practical foundation for integrating precise positive-displacement pumping into a production process.
The eVmP family uses a rotating and reciprocating valve-less ceramic piston. Its fluid cycle relies on the piston rather than external supply and discharge valves, giving the pump a compact positive-displacement path for repeated liquid handling.
The piston draws fluid into the pump head through the available inlet path.
The piston rotates to seal the inlet as the valveless ceramic-piston mechanism changes position.
The piston moves to deliver the metered liquid through the discharge path.
The drive repeats the programmed cycle for continuous metering, single or multiple dispense, flow dispense, flow direction or suck-back operation.

The VS10-Series combines milliliter-scale displacement with programmable servo control for applications that need repeatable liquid handling at larger output volumes. Zaxis resources describe uses across diagnostic reagents, buffer dispensing, pharmaceutical work, chemical processes, OEM instruments and electronics fluid metering.

The eVmP family covers several dispensing ranges and configurations. Choose the VS10-Series when a milliliter application benefits from a V6SAN-W head, servo-driven control, nearly 10 mL per stroke and 6 L/min at 600 RPM capacity. The M Series addresses microliter dispensing, while the V Series is another milliliter valveless metering option; enclosure models package eVmP pumps for benchtop or dual-pump applications.
