See the official PDF for exact tabulated motor-pump unit dimensions (Dimensions A, B, C, D) and detailed parts list with material codes.

Safety Note: All High Pressure Systems require a primary pressure regulating device (e.g., regulator, unloader) and a secondary pressure relief device (e.g., pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to pump or property.
