1. A method comprising:
operating one or more clean pumps to pump a non-gel fluid having no proppant added thereto; and
operating one or more dirty pumps to pump the dirty stream, the dirty stream comprising a solid material disposed in a fluid carrier, wherein the solid material is a proppant with a concentration of the proppant in the fluid carrier of about 2 to 12 pounds per gallon, wherein the dirty stream causes a useful life of the one or more dirty pumps to be shortened relative to a reduction in a useful lie of the one or more clean pumps due to the non-gel fluid, wherein a manifold receives the non-gel fluid downstream of the one or more clean pumps, the non-gel fluid received by the manifold is discharged directly from the one or more clean pumps, the non-gel fluid and the dirty steam are combined at the manifold and together form an oilfield fluid to be transmitted from a well surface to a wellbore.
