DC 80-EM Test Stand

The Merlin DC 80-EM is a low profile test stand, designed principally for the calibration of larger, single cylinder fuel injection pumps as found in marine, rail and heavy-duty industrial applications. The DC 80-EM has Flywheel, Inertia and drive specifications tailored to suit customer requirements.

Model DC 80-EM incorporates the Merlin S600M/20 positive displacement metering unit, replacing graduates fitted to the standard unit. Monitoring and measurement in bar graph and numeric format on a 10″ TFT colour display. Input/output data and control of measuring system is either by touch screen menu or soft touch push button switches.

A  unique robust heavy duty design weighing 5080kg the DC 80-EM gives the customer multiple options to meet the challenges of testing industrial size Bucket and Roller type pumps.

A DC Thyristor controlled, fan vented motor is controlled via a rotary potentiometer with a variable ramp rate pre-set by digital control.

Water cooled heat exchanger with microprocessor-based digital controller with thermocouple.

Large scaled graduates for high volume accuracy.

Flywheel in excess of ISO standards.

Mobile calibrating and injector mounting rigs are also available for testing heavy-duty multi-cylinder fuel injection pump (C series/R series).
