The F800HL mud pump is an advanced development derived from the conventional F800 model, designed to address the gap in the market for high-pressure pumps in the mid-power range. While standard F800 pumps typically deliver 35 MPa, this new model draws on the proven design concept of the other high pressure mud pump to achieve a maximum working pressure of 7000 PSI with a displacement of 38.9 L/s. This makes it the first of its kind in the industry, combining compact horsepower with exceptional pressure performance.
