The max pressure for F500, F800, and F1000 pump is 34.5MPa (5000PSI). These pumps are small, light and reliable. They are the best choices for shallow well and mid-deep well drilling rigs. The max pressure for F1300/1600, F22000 pump is 34.5MPa (5000PSI). These pumps are the best choices for mid-deep well and deep well drilling rigs due to its large displacement and high reliability. The max pump pressure for F1600HL and F22000HL pump is 34.5MPa (5000PSI), and the max displacement can reach 51.85L/S and 77.65L/S respectively. It is the best choice for deep well, super deep well, large displacements horizontal well, high pressure jet bit drilling, off-shore platform and other drilling rigs. The F1 series light weight pump is a new product. Under approximately equivalent power, displacement, pump pressure, and other basic conditions, the pump weight is 20% to 25% lighter than same model of F series. Meanwhile, all fluid end parts are forgings with outstanding quality. This pump is used when size and weight of drilling rigs are highly demanding, such as offshore platform drill rigs
