Pumps for Wellhead Control and Other Hydraulic Applications

Dynex manufactures a line of hydraulic Components including 15,000 psi pumps and valves for wellhead control and other applications. Our compact water-glycol pumps are maintenance free & provide a cost efficient alternative to plunger pumps. Our mineral-oil pumps are used for 0.75-HP low-energy panel systems.


 Products

  • PF500 Series Mineral-Oil Hydraulic PumpsCheckball
    Mineral-oil pumps operate at 10,000 psi. Reduced input power requirements as low as 1.0 HP makes them ideal for remote solar-powered panel systems. These compact pumps are also used on power packs tor high-torque service tools. <br />...

  • Checkball design pumps provide long life and greater volumetric efficiency, especially at high pressures. Individual piston check valves direct flow from the inlet side of the pump to the outlet port in these high-pressure hydraulic pumps.

    These pumps are ideal for systems with demanding conditions including pressure spikes, contamination, dirty environments, extreme temperatures and long duty cycles.

    Split-Flow models with multiple outlets supply flow for synchronized movement with greater accuracy than flow dividers. They can efficiently supply flow in a Hi-Lo circuit with changing flow and pressure requirements.

    Maximum Output Flow:
    At 1500 rpm, 0.57 US gpm;
    At 1800 rpm, 0.68 US gpm

    Maximum Pressure:
    8000 to 10,000 psi

    Speed:
    Rated, 1800 rpm
    Maximum, 3600 rpm

    Mounting:
    S.A.E A-A 2-bolt pattern

  • PF4300 Series Water Glycol Pumps
    Pumps operate to 15,000 psi on wellhead control and subsea systems. The single-fluid design needs no separate lubrication circuit, avoiding the cost of ongoing maintenance. They provide reliable operation on unmanned, deepwater platforms around the world....

  • Dynex pumps use the water-glycol to lubricate their internal bearings. Therefore, this design eliminates the potential for cross-fluid contamination, which can occur in other designs requiring a secondary oil for lubrication. This design provides lower systems costs with many benefits:

    No regular maintenance of lubrication circuit

    Less piping for lower-cost installation

    Easy vertical mounting in water glycol reservoirs

    Less weight, size and cost than triplex or plunger pumps

    Longer life with no cross-fluid contamination

    Ideal for remote, unmanned deepwater platforms

    Maximum Output Flow:
    At 1200 rpm, 5.5 US gpm;
    At 1800 rpm, 8.2 US gpm

    Maximum Pressure:
    8000 to 15,000 psi

    Speed:
    Rated, 1200 rpm;
    Maximum, 1800 rpm

    Mounting:
    S.A.E D 4-bolt pattern
