suction nozzle design

  • Inlet Design - Pumps

    Suction Feed. Piston pumps have better suction lift performance than plunger pumps. Piston pumps have more suction lift because of their flow through design, continuous forward flow design, and mechanically actuated inlet valves. For this reason piston pumps are the preferred choice for suction feeding applications.
