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.

VMP-OEM-V Drive
The VMP-OEM-V is our stepper–driven motor drive, designed for V series pump heads. VMP-OEM-V Pumps are ideal for a very wide range of applications, including neat chemistry, and some slurries, pastes, gels, or creams. Flow rates are typically less than 1000 mL/min, and under 100 PSI, making the V Series is one of our most popular pumps. Each VMP-OEM-V Drive is standard with RS485, PLC I/O, and Ethernet connections.
VMP-OEM-VS Drive
The VMP-OEM-VS is our servo–driven motor drive, designed for V series pump heads. The Servo Drive is ideal for more demanding applications with higher flow rates, higher pressure, or higher viscosity applications. With nearly 4 times the torque, the VS series drive can handle flow rates near 2,000 mL/min and back pressure up to 200 psi, while accepting common V series pump heads. Each VMP-OEM-V Drive is standard with RS485, PLC I/O, and Ethernet connections.

Engineering
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.
