OEM Metering Pumps.

Automatically adjustable electronic variable metering pump.

Automatically Adjustable Variable Metering Pump

The eVmP or electronic variable metering pump is a patented, programmable, fluid dispensing and metering device, complete with integrated industrial Ethernet and serial controls. The dispense volume is automatically adjustable from mLs to uLs.Automatic variable metering pump.

Changing system and fluid dynamics are easily overcome by electronic changes to stroke volume. eVmP’s small size allows it to be utilized in close proximity to bulk chemistry, or onboard management of discrete, fluid recipe and process control.

Why eVmP

The eVmP uses Zaxis’ internal ceramics, designed for millions of maintenance free cycles, and drift free accuracy. Valve-less, ceramic internals provide syringe-like precision and accuracy without the throughput limitations or excessive maintenance costs to wear items, or the costly inaccuracy of tubing and diaphragm pumps.


Complete with our Touch Screen Interface (TSi), all fluid control parameters are programmable, utilizing two precision stepper motors for pump volume and speed adjustments. TSi allows for plug and play with up to sixteen systems. PLC communication is Ethernet and 1/2 duplex RS485 selectable, with control up to 128 systems.

Features include:

  • Millions of no maintenance cycles
  • 1% accuracy or better with no drift
  • Patented, automatically adjusted dispense volume
  • Independently controlled stroke rate and displacement
  • Valveless piston design
  • PC interface with control up to 128 pump modules
  • Up to 100 programs
