Benefit
|
What It Means
|
|
No Valves
|
No valves to clog, leak, hang up or service.
|
Service, maintenance and down time are considerably reduced. Fluid connections and leak possibilities considerably reduced.
|
| Ceramic Internals |
Wear and abrasion resistant. Corrosion resistant fluid path
|
Superior material stability will provide millions of service free cycles.
|
|
One Moving Part
|
The piston is the only moving part in the pump.
|
Unique design enhances reliability and simplifies trouble shooting, service and down time. No tubes to change.
|
|
Accuracy - better
than ± 1%
|
Consistent precise output with all FMI pumps. Accuracy is held from microliters to the full flow range.
|
Output does not change more than ± 1% of set value. An important cost saving factor considering the waste generated by inaccurate pumps. see our Pay back Calculator
|
|
Drift Free Operation
|
Set values do not drift or change with time.
|
Long term, consistent, drift free, accurate pumping.
|
|
Precision Dispensing
|
Repetitive dispensing with better than +/- 1 % accuracy, % CV less than or equal to 0.5 %.
|
Single shot or repetitive dispensing of very low volumes, microliters.
|
|
Flows from 0 to 4600 ml
per minute
|
Wide range of flows. From microliters to 70 gal/hr.
|
Accuracy of ± 1% is maintained from one drop dispensing to 4600 ml/ min. pumping.
|
|
Positive Displacement
|
Unaffected by back pressure of up to 100 PSI.
|
Will maintain output flow against discharge pressures of up to 100 PSI.
|
|
Viscosity Independent
|
Unaffected by viscous fluids.
|
As long as the material flows or is pressure fed into the pump, we will pump it out.
|
|
Self Priming
|
Pumps will self prime to 15 feet.
|
The pumps suction stroke will pull a vacuum of 15” Hg dry, 26” Hg wet.
|
|
Variability
|
Fine flow adjustment capabilities
|
Easy adjustment of flow with high degree of accuracy. Flow can be adjusted while the pump is working.
|
|
Dimensionally Stable Materials
|
Materials used will not change or be affected by pressure and most fluids.
|
Ceramics, carbon and stainless steel, provide broad fluid compatibility for dependable long life operation.
|
|
Chemical & Corrosion Resistant
|
Inert and corrosion resistant fluid path.
|
Pump construction materials are versatile and are unaffected by most chemicals. Chemical compatibility must be verified.
|
|
Repeatability
|
Change settings with precision accuracy.
|
Flow setting can be changed and then reproduced within 0.1% of original setting.
|
|
Instant Reversibility
|
Will pump in either direction.
|
Reverse pumping direction while the pump is working, without disassembly
|
|
Modular Design
|
Interchangeable pump head modules and pump drive modules, provide numerous flows and material combinations.
|
Pump drives will accept different size pump heads. Quick modular online change reduces down time to minutes.
|
|
Delivery from Stock
|
No waiting time.
|
We will ship the same day if order is placed before 2 PM.
|
|
Large Selection of
Pump Drives
|
AC, DC, air, explosion proof, fixed, stepper or variable drives.
|
We have many standard drives to suit all applications including pedestal models to be used with customers own motor.
|
|
Reliability, Innovation,
State of the Art Design
|
Valveless metering pump experts since 1959. FMI pumps are used in the most advanced hi-tech applications and designs.
|
Our pumps are covered by 7 US patents and many foreign patents. They are mentioned and used as part of 78 different patents.
