eVmP Smart Pump System

Automatically adjustable electronic 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.

Flexible Automated Dispensing

Flexibility is a valuable attribute in automated production systems. Many automation systems can be described as Fixed or Hard, meaning they have been designed for a single product or specific task. These specified systems are often too rigid to be reused or adapted to any purpose outside of its original design. Metered dispensing in automation often faces the same flexibility issues. An automated dispensing system with the ability to dynamically adjust volume is key to a lean production line.

The patented eVmP system is a precision metering and fluid dispenser combined with a detachable Touch Screen Interface (TSi) for simple programing and immediate teach and control.


The eVmP Micro is an automated variable metering pump used for fluid dispensing and metering. The eVmP uses internal ceramics that are designed for millions maintenance free cycles with minimal to zero downtime. The valve-less ceramic internals provide syringe-like precision with drift free accuracy. We’ve eliminated the inaccuracy associated with tubing and diaphragm pumps and built a robust system that is precise and dependable.


We’ve made the sophisticated capabilities of the eVmP surprisingly accessible. You can set all fluid control parameters with an intuitive touchscreen interface. It’s a plug and play system that can control up to 32 separate units.
