A version of the EXtronic dosing pump featuring internal control has been announced by ProMinent Fluid Controls.

The EXtronic is a precision dosing pump which is available in versions which have been approved to the EG-EX-directive 94/9/EG (ATEX) for metering fluids in gas explosion endangered operations (Zone 1, group II) or storm endangered mining operations. Compliance with the ATEX Directive has been mandatory since July 2003.

The new internal control version of the pump features stroke length adjustment from 1:10 and a stroke rate adjustment of 1:25 giving a total adjustment range of 1:250.

The short-stroke solenoid drive  and complete pump control are integrated in the pump housing where the drive is not only protected against explosions, but also has contact and moisture protection IP 65 in accordance with DIN 40050 even when the front cover is open.

There is also a new operating voltage of 500V which expands the range of applications to include storm endangered mining operations.

The EXtronic pumps have a capacity range from 0.23 I/hr up to 60 I/hr at back pressures up to a maximum of 25 bar.
