A new range of valveless dispensers and metering pumps are designed for laboratory, analytical, industrial and OEM applications and feature just one moving part, the piston
Integrated Dispensing Systems announces the introduction of an exciting new range of Cerampump Valveless Dispensers and Metering Pumps.
These pumps are designed for laboratory, analytical, industrial and OEM applications.
The valveless pumping function is accomplished by the synchronous rotation and reciprocation of the ceramic piston in the precisely mated ceramic cylinder liner.
Once complete piston revolution is required for each suction/discharge cycle shown.
The piston always bottoms for maximum fluid and bubble clearing.
Moving the pump head position changes the piston stroke length and in turn the flow rate.
Infinite fine flow adjustments between from 0 - 100% flow rate are possible.
An optional flow rate indicator provides for accurate and simple linear calibration.
The flow rate can even be changed while the pump is operating or at rest.
Some of the benefits of these pumps are as follows: No valves to clog, hang-up or service; One moving part (the piston); Accuracy of better than +/- 1% (Drift Free); Precision dispensing - CV of 0.5% or better; Flow rates from Microlitres to 4600 ml/min; Positive displacement up to 100 psig (back pressure); Viscosity independent - Unaffected by viscosity of fluids; Millions of Maintenance Free Cycles; Inert and corrosion resistant fluid path, ceramic and fluorocarbon as standard; Self Priming to 15 feet; Instant Reversibility - will pump in either direction; Large selection of drives, fixed, variable, pneumatic, stepper and Explosion Proof; and Fast delivery from stock.
