Reciprocating Plunger Pumps

  • RDP Reciprocating Pump

    Triplex and Quintuplex type plunger pumps 
    The RDP series is a range of plunger pumps in a variety of sizes, available in triplex and quintuplex configurations. They are constructed in accordance with the latest edition of API 674 and ISO 13710 for high-pressure applications.

    Drift boundaries
    Capacity: up to 366.50 m³/h (1611 gpm).
    Pipe size: 25 to 200 mm (1 to 8 inches).
    Maximum pressure: up to 1100 barg.
    Temperature: -40 to 200 °C (-104 to 392 °F).
    Speed: up to 450 rpm.

    Areas of application
    Methanol injection, carbon dioxide (CO2), glycol circulation, seawater injection, produced water disposal, reverse osmosis (seawater desalination), water treatment, production and jetting, hydrocarbons (condensate), pumps for closed drain systems, slops injection, boiler feed water, fertilisers (carbamic and ammonia), steelworks (high-pressure scale removal), and blow-out preventer valve (BOPV) activation.

    OVERVIEW
    The RDP series of Reciprocating Plunger Pumps is suitable for handling most liquids within the oil and gas industry and wastewater treatment. Ruhrpumpen's RDP pump series is a type of positive displacement pump where a smooth, cylindrical plunger slides through the seal. This distinguishes it from classic piston pumps and enables higher pressures.

    PROPERTIES
    • A range of different sizes in Triplex and Quintuplex configurations.
    • Designed in accordance with API 674 3rd Edition and ISO 13710.
    • Allows access to service points, reducing maintenance time.
    • Robust design with low noise and vibration characteristics.
    • High operational efficiency.
    Extensive range capability.
    • Design life of 20 years.

    DESIGN FEATURES
    • Excellent noise and vibration properties < 85 dB(A).
    • 95 % volumetric efficiency and 90 % mechanical efficiency, which exceed API standards.
    The stuffing box can be removed without dismantling the pump.
    • Spring-loaded, self-adjusting braided packing and V-packing (chevron packing) minimise leakage.
    • Cartridge valves for easy removal and replacement.
    • Can be configured with various drives, lubrication systems and base frames (skids).

    PUMPING STATION OPTIONS 
    Can be manufactured to meet specific specifications such as:
    • NORSOK
    • ASME
    • RUSSIAN CU TR
    • SHELL ES 135
    • Statoil TR1655
    … and many more.

    • Pulsation dampeners, safety relief valves (SRVs) and instrumentation can be mounted directly onto the pump head.
    The engine can be mounted directly on top of the crankcase for a compact offshore installation footprint.
    • ATEX compliance.
    Condition monitoring of the entire pump system.
    • Various options for lubricating seals and the drive (power end).
    Electric motor.
    • Diesel or petrol engine.
    Hydraulic motor.
    • Frequency converter (variable speed drive).
    • Various transmission options, including: Gearbox / V-belt drive.

    CONSTRUCTION MATERIALS
    Ductile iron housing with customer-specific lacquering.
    • Wetted parts can be manufactured from a wide range of alloys, including in accordance with NACE and NORSOK requirements.
    All materials supplied are of high quality, and Non-Destructive Testing (NDT) can be tailored to meet the project's specific requirements.
