Engineering Metering Pumps

eVmP (Electronic Variable Metering Pump)

Patented Design of Metering Pumps

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. This pump technology combines precision ceramic pump components and an electronically controlled linear stepper actuator to make ultra-fine adjustments to angle position, thereby changing the volume of metered liquid. This allows the eVmP system to provide dynamic fluid displacement to overcome variations in viscosity and surface tension. The eVmP is the latest in fluid metering and dispense technology.

The Ceramic image depicts the use of durable ceramic internals designed to resist wear and chemical corrosion.

Ceramic Internals

Durable, long lasting, abrasion resistant

The Valveless image highlights the pump design with no check valves, using geometry and mechanics for flow control.

Valveless Design

Easy to clean, easy to maintain, simple changeover

The Electronic image emphasizes a digital adjustment interface for controlling the pump’s output.

Electronic Variability

Simple "Push Button" displacement adjustment

The Positive image shows arrows representing fluid moving in a forward direction.

Positive Displacement

High accuracy and repeatability (accuracy is within 0.5%)

Rotating and Reciprocating Valve-Less Ceramic Piston Design

  • Extremely tight tolerances bring accuracy and repeatability
  • No external supply and discharge valves, the intake port is always connected to the discharge port
  • Valveless and only one moving part, yielding millions of maintenance-free cycles
