    1. INTRODUCTION This operator's manual contains information needed to install, operate, and perform minor maintenance on the MX-Class Pump. Description of the MX-Class Pump The MX-Class pump is designed to be a reliable component within basic analytical or sophisticated research instruments, in routine HPLC analyses or as a dependable metering pump for general laboratory or industrial use.

  • Page 7: Self-Flushing Pump Head

    Self-Flushing Pump Head Self-flushing pump heads provide continuous washing of the piston surface without the inconvenience of a manual flush or gravity feed arrangement. The self-flushing pump head uses a diaphragm and secondary set of check valves to create a continuous and positive flow in the area behind the high-pressure pump seal.

    3. INSTALLATION Unpacking and Inspection Prior to opening the shipping container, inspect it for damage or evidence of mishandling. If it has been damaged or mishandled, notify the carrier before opening the container. Once the container is opened, inspect the contents for damage. Any damage should be reported to the carrier immediately.

  • Page 11: Cavitation

    It is recommended to sparge the solvent vigorously for 10 to 15 minutes before using it. Then maintain a trickle sparge during use to keep atmospheric gases from dissolving back into the mobile phase. The sparged solvent must be continually blanketed with helium at 2 to 3 psi.

  • Page 12: Instrument Installation

    It is also recommended to avoid ammonium hydroxide. Although ammonium hydroxide will not harm the pump itself, it is likely to damage the stator and rotor in injection valves. Instrument Installation Mobile Phase Reservoirs The mobile phase reservoir should be placed at the same level or slightly higher than the pump, never below the pump, and the inlet tubing should be as short as practical.

    To prime the flush lines for a self-flush head, simply place the inlet line in the flush solution and connect a syringe to the outlet line and apply suction until the line is filled with flush solution. Place the outlet line in the flush solution. Secure both flush lines in the flush solution container so they stay immersed during pump operation.

    4. OPERATION Front Panel Controls and Indicators Figure 2, MX-Class Pump Front Panel Components Prime/Purge Valve CAUTION: When the PRIME button (P) is pressed, the pump will run at the maximum flow rate. Be sure the prime/purge valve is open. The prime/purge valve vents the flow to atmosphere and permits efficient priming of the MX-Class pump.

    Power-Up Configuration On power-up, press and hold the MODE button to access the PUMP SETUP MENU. The LED display will briefly show “SETUP”, and then enter the pump setup menu. Each setup parameter includes a TITLE screen followed by a VALUE screen. Within the pump setup menu, use the MODE button to cycle forward through the menu screens;...
  • Page 18 Solvent Select: The next setup parameter displayed is the Solvent Select feature, denoted by the title screen “S-Sel”. Press the MODE button to advance the menu screen to display the currently selected solvent, or OFF if this feature is disabled. Solvent Select (not available on MX model pumps) allows the pump to produce accurate flow rates for various solvents.

  • Page 19: Non-Volatile Memory Reset

    Non-volatile Memory Reset On power-up, press and hold the UP ARROW button to perform an instrument reset. The LED display will briefly show “reset”, and then enter the normal pump operating menu. A rest restores the instrument to its original factory settings. A reset automatically occurs when the firmware is updated.

    9. Carefully separate the self-flush housing from the pump. Move the flush housing straight out from the pump and remove it from the piston. Be careful not to break or damage the piston. 10. Remove the self-flush diaphragm from the piston by carefully grasping the sealing flange on two sides and sliding it straight out on the piston being careful not to exert side pressure that may break the piston.

  • Page 24: Piston Seals

    Figure 6, Pump Head Self-Flush Assembly Piston Seals Replacing Piston Seal Lower than normal pressure, pressure variations, and leaks in the pumping system can all indicate possible problems with the piston seal. Depending on the fluid or mobile phase used, piston seal replacement is often necessary after 1000 hours of running time.

  • Page 25: Replacing The Seal

    Replacing the Seal 1. Place a high-pressure replacement seal (Figure 7) on the rod-shaped end of the seal insertion/removal tool so that the energizer side is visible when the seal is fully seated on the tool. Insert the seal into the pump head so that the energizer side of the seal enters first, facing the high-pressure cavity of the pump head.

  • Page 26: Replacing The Piston

    5. Use the scouring pad included in the seal replacement kit to clean the piston. Gently squeeze the piston within a folded section of the pad and rub the pad along the length of the piston. Rotate the pad frequently to assure the entire surface is scrubbed.

  • Page 27: Check Valve Replacement

    If this procedure does not return the pump to proper performance, the check valves should be replaced. An example of new check valves from their package can be seen in Figure 8 below. Check Valve Replacement Figure 8, New Check Valves from package and proper orientation. 1.

    Figure 9, Check valve assembly. Note: The Sapphire Seat is an opaque white ring. The red ruby ball can be seen through the ring. Flow is always away from the sapphire seat, as shown by the directional arrows etched on the capsules. The capsules also include one removable PTFE seal (as shown in Figure 10 above).

  • Page 29: Lubrication

    The pump is now prepared for any mobile phase or short- or long-term shutdown. Lubrication The MX-Class pump has no lubrication requirements. The bearings in the pump housing and piston carrier are permanently lubricated and require no maintenance. Keeping the interior of the pump free of dirt and dust will extend the pump’s useful life.

    4. Customer supplied 1/8"OD tubing can now be connected to the inlet of the pump. *Note – minimum tubing ID for inlet of pump should not be less than 0.085”, or cavitation may occur. To convert the outlet connection: 1. Use a 5/8” wrench to hold the filter housing at the pump, and a 1/2" wrench to remove the filter closure assembly, loosen closure and pull the filter closure assembly out of the filter housing, making sure to remove the PEEK filter housing gasket with the closure assembly.
