  • Apparatus and system for a thrust-absorbing horizontal surface pump assembly
    Patent number: 10036398
    Abstract: An apparatus and system for a thrust-absorbing horizontal surface pump assembly. A thrust-absorbing horizontal surface pump system includes an intake chamber including a stationary thrust bearing paired with a rotatable thrust runner to form a thrust bearing set, wherein a first face of the stationary thrust bearing positioned towards the rotatable thrust runner is at least partially diamond-coated, and wherein a second face of the rotatable thrust runner positioned towards the stationary thrust bearing is at least partially diamond-coated, a fluid entrance that receives fluid into the intake chamber, and a pump inlet that receives the fluid into the multi-stage centrifugal pump, wherein the thrust bearing set is arranged around the intake shaft such that during operation of the electric motor the thrust bearing is in a pathway of the fluid as the fluid flows between the fluid entrance and the pump inlet.
