    The RS is Carver Pumps’ process duty, horizontal ring section multistage pump. Designed for moderate to high pressure pumping, the RS is available in seven basic sizes with overall performance to 2,600 HP.

    The RS is offered with Class 300 ANSI R.F. inlet flanges and Class 600 or 900 ANSI R.F. discharge flanges, depending on the pressures and number of stages involved. Hydraulic performance extends to 2,000 GPM and 3,400 ft. TDH, making it ideally suited for the most demanding industrial and process applications.

    The RS design incorporates a product-lubricated, advanced composite material, sleeve-type radial bearing at the outboard (discharge) end. The thrust bearings are two matched angular contact ball bearings located at the inboard (suction) end of the pump. An optional outboard mechanical seal with an inboard radial ball bearing is also available.

    The RS has oil-lubricated ball bearings, which can be water cooled. Larger units can also be fan cooled. The available materials of construction, from ductile iron to duplex stainless steel, offer combinations suitable for all applications from general water services to light abrasives and corrosive applications. Our proprietary advanced composite material, available for wear rings and interstage bushings, offers high-temperature performance, and exceptional resistance to wear and corrosion.

    Many other options and arrangements, such as turbine and magnetic drive units, are also available. These options offer the benefits of:
    • Maximum safety
    • Maximum installation flexibility
    • Maximum fluid compatibility
    • Higher efficiencies
    • Longer component life
    • Minimal downtime
    Together these benefits add up to lower total costs of ownership.
