Fluid
Metering Inc. is located about 30
miles from New York City in Syosset, Long Island. FMI pioneered the first
patented valveless rotating and reciprocating piston metering pump concept
and has been delivering pumping excellence and precise fluid control for
over 40 years.
A unique valveless design
features one moving part and an inert, corrosion resistant fluid path of
ceramic and fluorocarbon, providing precise, drift-free fluid dispensing
& metering.

CeramPump®
Principal of Operation
Pump
Operation: The
valveless pumping function is accomplished by the synchronous rotation and
reciprocation of the piston in the precisely mated cylinder liner. One
complete piston revolution is required for each suction/discharge cycle as
shown. The piston always bottoms for maximum fluid and bubble clearing.
|
| The
piston rotates and reciprocates. As the piston is pulled back and the
piston flat opens to the inlet port, suction is created and fluid fills
the pump chamber. |
The
inlet port is then sealed and crossover occurs. As the inlet port is
sealed and the pump chamber is full, the outlet port opens up. Only one
port is open at any time and at no time are both ports interconnected. |
The
piston is forced down and the piston flat opens to the outlet port.
Discharge is created and fluid is pumped out. The piston bottoms for
maximum bubble clearing. |
The
outlet port is sealed and the pump chamber is empty, the inlet port opens
to start another suction stroke. |
Easy Flow Rate
Adjustment
- Moving the pump head position changes
the piston stroke length and, in turn, the flow rate.
- Infinite fine flow adjustments between
0-100% flow rate..
- Flow rate indicator provides for
accurate and simple linear calibration.
- Flow rate can be changed while pump is
operating or at rest.

CeramPump®
"No-Valve" Technology
- The valveless pumping function is
accomplished by the synchronous ;rotation and reciprocation of the
ceramic piston in the precisely mated ceramic cylinder liner.
- One complete piston revolution is
required for each suction/discharge cycle.
- Moving the pump head position changes
the stroke length and in turn the flow rate. Flow rate indicator
provides for simple and accurate flow rate adjustment
