  • Page 4: Warnings

    SECTION 1 WARNINGS The MSI Hybrid™ Well Service Pump is used in high-pressure and high flow well service applications. High pressure equipment, if not used and maintained properly, can cause serious injury or death and damage to equipment and property. Not taking proper precautions and failing to perform routine maintenance and inspections can also contribute to loss of well control, and such loss could cause serious injury or death and damage to equipment and property.

  • Page 5: General Description

    The MSI Hybrid™ Well Service Pump is rated for pumping fluids up to 15,000 PSI or at flow rates up to 929 GPM. With different materials it can handle many fluid types, including abrasive and corrosive fluids. Seals are also available for low temperature and CO applications.

  • Page 6: Pump Performance

    Pump Performance The MSI Hybrid™ Well Service Pump can be equipped with 2.75", 3.00", 3.25", 3.50", 4.00", or 4.50" diameter fluid end plungers. There are two Xtreme Service™ fluid end sizes, one accommodates plunger sizes 2.75" – 3.00", and the other accommodates plunger sizes 3.25" – 4.50".

    (PTO) from the crankshaft. This approach to determining lubrication cycles eliminates over or under lubricating and ensures lubricant is supplied whenever the pump is in motion. The Auto-Lube™ System can be used in conjunction with the MSI Lube Relief System™ to provide outstanding lubrication performance.

  • Page 33: Charge Pump Intake

    MSI therefore recommends the use of a centrifugal charge pump as part of a properly designed supply system. Well service pump cavitations will occur if the pump suction pressure drops to a level approaching the vapor pressure of the fluid being pumped.

  • Page 34: Pump Discharge Requirements

    Never operate this MSI pump without a suitable pressure relief device set for the maximum pressure that the well service pump and all connected piping and equipment can be safely operated.

  • Page 35: Lubrication Requirements: Power Train And Plungers

    Lubrication Capacity Requirements The MSI Hybrid™ Well Service Pump is a dry sump, i.e., it is not intended to contain a volume of lubricating oil. A separate lubrication oil reservoir is required with a 50 gallon minimum capacity; it should be installed below the plunger pump power end.

    Lubrication Relief Valve A relief valve should be part of any MSI Hybrid™ Well Service Pump lubrication system. MSI recommends a relief valve that is rated for 20-25 GPM and 60-200 PSI to relieve excess pressure which could damage filters, lines, gauges, or other connected equipment.

  • Page 39: Lubrication Attachment Points

    Consult MSI Engineering if assistance is required in selecting a lubricant. Oil Change and Oil Types MSI recommends that oil condition be monitored, and samples should be tested by a certified laboratory to determine the optimum frequency for oil changes. Laboratory testing can also aid in identifying pump damaging particles that may originate from unsuspected sources such as low quality lubricants or filters.

  • Page 40: Cleaning Plunger Lubrication Drip Pan

    The drip pan is intended to collect plunger lubricant that bypasses the sealing element. To clean the pan remove the screws and slide the pan out from below the pump. Clean then reinstall it. Revision K 03/12/2019 MSI - A Division of Dixie Iron Works, Ltd. All rights reserved. Page 37...

  • Page 41: Start-Up And Shut-Down

    Replace immediately if the tension indicator is not functioning. *If your MSI Hybrid™ Well Service Pump is equipped with an Xtreme style fluid end, it will have large Maxbolts™ installed longitudinally through the fluid end. The tension on these bolts is pre-set at the factory and should not need adjustment.
  • Page 42 The packing in this pump is non-adjustable; therefore, fully tightening the packing nut is required to properly set the gland length. See Section 9.2 for instructions on this. Revision K 03/12/2019 MSI - A Division of Dixie Iron Works, Ltd. All rights reserved. Page 39...

  • Page 43: Shut-Down Procedure

    4) Close any valves necessary to isolate the pump from well service fluid in the circulation tank. 5) Leave the prime mover running so that oil to the MSI Hybrid™ Well Service Pump will continue to circulate and cool down any internal parts that were under heavy load prior to the shut-down.
