The Intelligent Programmable Pump from Fluid Metering combines FMI’s precision valveless STH Stepper Pump with integral programmable driver in a compact design ideal for integration with OEM instrumentation. The driver provides precision servo control of the STH pumps stepper motor for resonance-free, quiet operation. With five programmable inputs and two outputs, the pump is compatible with multiple programming platforms including, Visual Basic, C/C++, Delphi, LabView. Analog 0-5 VDC, RS-232, and CANopen protocol. The rotating and reciprocating piston accomplishes both the pumping and valving functions, effectively eliminating check valves present in conventional reciprocating piston and diaphragm pump designs.
