How the Quantex Pump works
The Quantex pump is a two-part plastic moulding with a central rotor and an outer housing.
The rotor has indents that pick up fluid from the input side and transport it round the housing to the output port. A flexible diaphragm on the housing pushes the fluid into the output, emptying the indents. Because the indents running against the housing form a fixed volume, and the emptying is very efficient, high accuracy is achieved.
Quantex owns a portfolio of patents which describe this novel approach to pumping fluids; see for example PCT application WO2006/027548.
This simple mechanism can run at a wide range of speeds to match the particular requirement. At very low speeds there is no leakage of fluid, so accuracy is maintained down to very low flow rates.
The flow rate of the Quantex pump is controlled by the rotation rate. The flow rate is directly proportional to the rotation rate You can use over a 1,000 to 1 ratio of speeds, making it a very simple and versatile technology to adopt.
