It is the classic Euro II mechanical in-line and distributor pump calibration platform - BH6PA110, 127-8207 (CAT in-line), and VE-type distributor pumps. With optional cam boxes it extends to EUI EUP unit injectors (VW T5 PD, Detroit 60, MAN / Mercedes, Cummins).
12-cylinder drive with motor options: 7.5KW / 11KW / 15KW / 18.5KW / 22KW, in 380V 3-phase or 220V single-phase. Note: there is no 17.5KW motor - customers asking for 17.5KW usually mean 18.5KW.
With the optional common rail capability it covers Bosch 0445110183 (Fiat 1.3 Multijet), 0445110369, 0445110441, 0445110557, 0445110698, Denso 095000-6471 (John Deere 6090), and Delphi 28353991 (Mercedes).
Yes, with a cam box (TU-A/TU-B for Detroit 60, TU-C/TU-D/TU-E for VW/MAN/Mercedes/Cummins) plus the Beijing system (BEI-B with screen recommended) for the test data.
No. As a mechanical Euro II platform it does not support remote operation. Machines with the Beijing system (CR919, CR708, EPS205 etc.) support remote operation; the 12PSB-style mechanical bench does not.
