No adjustments are necessary due to the natural torque of the pump head on the pump tubes. The tension is self-adjusting and there is therefore no danger of over-tensioning.
The inbuilt microprocessor controls the following functions: change of flow direction; speed control; recording of running time; control of running intervals; pre-programming of variable
speed settings.
The electronics are housed in the pump head. This separation of wet and dry units prevents possible leakage from the tubes to the electrical components.
The KelRon?pump runs off a 12VDC supply which, when connected to a battery, is ideal for field use. It can also be connected to a 220 VAC electricity supply by means of an adaptor.
The KelRon?pump can be connected to an external computer using the specially developed KelRon? software. This software boasts of the following features: calculating the life left of each
respective tube, speed adjustments; displaying the accumulated flow rate, recording the volume delivered by each respective tube over a defined period.
An industrial model which does not have user-friendly electronics is also available. This model does however have various speed settings.
The KelRon?NT ?12 for small volumes can be modified to a KelRon?NT ?4 for large volume dosing by exchanging the fingers and pump tube holder. The flow rate can be increased further by
changing the gear ratio.
The flow rate ranges from 0,5ml/min to 7,7 ml/min per tube for the NT- 12. The NT-4 has a maximum flow rate of 110ml/min per tube. Should the gear ratio be changed, this can be increased to
220ml/min per tube.
The removable pump tube holders have been specially designed to offer the following advantages:
The pump tubes can b pre-installed in the system with ease.
The life of the respective pump tubes is extended considerabily due to the varying points of cantact of the rollers on the tubes.
The KelRon?can be connected to an autosampler.
The dimentions of the KelRon?pump are as follows:
Height: 260mm
Length: 310mm (NT-12)/ 360mm (NT-4)
Width: 153mm and 7mm for electric cord = 160mm
Mass: 12kg
