FAQ

Q: Can I change the color of the machine?
A: Yes, we offer Green, Red, Black, Blue, Grey, and Yellow. Please specify your preference when ordering.

Q: What is the difference between 7.5KW and 11KW?
A: 7.5KW is sufficient for most standard automotive pumps. 11KW provides higher torque, recommended for larger truck pumps or heavy-duty use.

Q: Does this machine test Common Rail pumps?
A: No, the MINI 12PSB series is for Mechanical Pumps (Inline, VE, Distributor). For Common Rail, please check our CRS series.
