The automatic lubrication system is connected to a control system via switchs. The control system may involve human input or may be computerised (computer numerical control or CNC). [2] [3] There are advantages of using an automatic lubrication system over a manual system. For example, there are savings in the costs of human resources. The ...
The RFA 300 pumps at flow rates less than 1 milliliter per minute through 1 millimeter ID glass mixing coils. Throughput on the RFA can approach 360 samples per hour, but averages closer to 90 samples per hour on most environmental tests. In 1986, Technicon (Bran+Luebbe) introduced its own microflow TRAACS-800 system. [11]

Deep well hand pumps are used for high lifts of more than 15 m. The weight of the column of water is too great to be lifted directly and some form of mechanical advantage system such as a lever or flywheel is used. High lift pumps need to be stronger and sturdier to cope with the extra stresses.
The automatic controls allow the pump to follow a set schedule of how much energy to consume during specific hours, which allows building owners to cut down even further on electricity costs. By dividing the output into a double pump in parallel design, the system is able to greatly adapt to partial load conditions.
