Vertical pumps

  • DSV Vertical Process Pump

    Powerful, double-suction, vertical process pump
    The DSV type is a powerful, vertical, single-stage, double-suction centrifugal pump with a twin volute casing. The DSV pump has good NPSH characteristics and is ideal for open sumps, channels, lakes, and rivers.

    Boundary limits:
    Capacity: 340 to 11,360 m³/h (1,500 to 50,000 gpm).
    Lifting height: 170 to 650 m (40 to 600 ft).
    Maksimalt tryk: op til 19 bar (280 psi).
    Temperature: up to 150 °C (302 °F).
    Outlet flanges: 12 inches to 36 inches.

    Areas of application
    Cooling towers and other applications that require large volumes of liquid with a relatively high head, as well as raw water intake.

    OVERVIEW
    The single impeller develops higher heads and capacities without the need for additional stages. This minimises the number of wear parts, resulting in easier maintenance and precise alignment. In contrast to the vertical turbine pump, this completely eliminates the use of intermediate bowl bearings, which are vulnerable when handling abrasive fluids.
    Without the limitation of a smallest possible diameter, as is the case with submersible pumps, the twin volute housing has larger water passages and low fluid velocities, which also reduces wear and minimises corrosion and erosion effects.

    PROPERTIES
    • Twin volute casing.
    • Lukket, dobbeltstrømmende pumpehjul.
    • Extended flared bell that guides fluid into the impeller.
    • Wear rings in the pump housing, which are tightly fitted to minimise liquid recirculation.
    • Ball bearings located in the intake funnels.
    Transition diffuser that ensures smooth hydraulic flow from the volute casing to the column pipe.

    Product Description
    • Vertical, space-saving construction.
    • Departure above or below the foundation (base).
    • Oil-lubricated column, or it can be force-lubricated by the pumped liquid.

    Without the limitation of a smallest possible diameter, as is the case with submersible pumps, the twin volute housing has larger water passages and low fluid velocities, which also reduces wear and minimises corrosion and erosion effects.

    PROPERTIES
    • Double volute casing designed to efficiently convert the velocity imparted to the fluid by the impeller into pressure.
    The pump housing is of a closed, double-flow centrifugal type.
    • Extended suction bell that directs fluid into the impeller.
    • Seal rings in the suction casing on both sides of the impeller.
    • Support bearings (bell bearings) in the suction funnels immediately adjacent to each side of the impeller.
    • Transition diffuser to ensure smooth hydraulic flow from the volute casing to the column pipe.

    Product Description

    OVERVIEW
    The VSP model, available in 28 different sizes, is a sump pump with a semi-open impeller designed for clean water. Ruhrpumpen also offers the VSP Non-Clog model, which is a solids-handling sump pump with a closed impeller. It is designed to handle water with solids (dry matter) up to 4″ in diameter and is available in 18 pump sizes.
    The standard construction for both types of our sump pumps is cast iron. However, all other sizes and material configurations can be manufactured to our customers' requirements.

  • VTG Vertical Turbine Generator

    Vertical turbine generators
    RP’s vertical turbine generators are essentially pumps running in reverse. When the flow through the pump is reversed, the impeller starts to rotate in the opposite direction, and the pump operates as a turbine.

    Boundary lines
    Capacity: up to 6,626 m³/h (29,174 gpm).
    Lift height: up to 1,067 m (3,500 ft).
    Maximum pressure: up to 105 bar (1,523 psi).
    Temperature: -185 °C to 121 °C (-300 °F to 250 °F).

    Areas of application
    Hydroelectric generators, industrial systems, water transport systems, dams, reverse osmosis, oil supply systems, chemical and petrochemical processes, and cryogenic closed systems.

    OVERSIGHT
    The motor that drives the pump can also function as a generator; when operating as a turbine, it captures mechanical energy and converts it into electricity. VTG (Vertical Turbine Generator) is particularly suitable for areas with constant head and flow, and its primary purpose is to meet smaller hydropower needs. [1]
    VTG is available for applications in cryogenic closed systems.

    PROPERTIES (CHARACTERISTICS
    • Multi-stage vertical centrifugal pump.
    • Closed and open impellers are available.
    • Tenants are product-smeared.
    • Different turbine methods for different operating conditions.
    Applications for use as either a pump or a turbine.
    • Available for applications in marshes or enclosed systems.

    DESIGN FEATURES
    • Semi-open runners, which are axially adjustable from the operating floor level.
    • Good efficiency and good choke-flow properties.
    • Discharge can occur openly into a sump or into a barrel in a closed system.
    • Latest API 610 (VS1) construction is available.
    Note: Depending on the turbine's materials and size, higher pressures or delivery heads may be possible; please contact Ruhrpumpen.

  • VTP Vertical Turbine Pump

    Vertical turbine pumps (VS1)
    The VTP pump series is normally constructed for operation in wells or sumps.
