1.00 General Description
The MSI TI-600 is a 600 horsepower triplex pump. The MSI QI-1000 is a 1000 horsepower quintuplex
pump. These pumps are suited for oilfield service applications.
These pumps are composed of three main components: Power Frame, Fluid End, and a Gear Reducer.
The pump is designed for sixteen left and right-hand configurations of the Gear Reducer without
removing the crankshaft.
The Power Frame is composed of the crankshaft, the crossheads, the crosshead guides, connecting rods,
and diaphragm seal housing in a high-strength steel frame. The Power Frame should be mounted to a
skid or other rigid platform before operating (see 1.30).
The Fluid End is composed of valves, springs, intake manifold, discharge flanges and various access
covers. The Fluid End is machined from a one-piece, high-strength steel forging. One Fluid End will
accept plunger sizes from 2.75 to 3.00 inches and the other plungers 3.25 to 4.50 inches in diameter.
The Fluid End is bolted to the Power Frame with high-strength tension-indicating bolts.
The Gear Reducer houses a helical AGMA #10 precision ground pinion and gear providing a reduction
ratio of 4.61:1.
1.10 Recommended Shipping and Storage
Every MSI pump is fully factory acceptance tested (FAT) at MSI before it is cleaned, painted, and
preserved for shipping. This FAT procedure runs the pump through the full range of horsepower and
pressure. During the FAT, water is used as the pumping medium. Once the test is completed, the water
residue in the fluid end is removed, and all fluid end internal parts are generously misted with water
displacing protective lubricant. Following the FAT, the insides of the gear reducer and power end are
fully coated with high grade lubrication oil. After final painting, the pump is shrink-wrapped to
prevent excessive exposure to humidity and rain. Desiccant packets are placed within the shrink wrap
to absorb internal moisture. If the pump is to be shipped overseas, it is also placed within a completely
enclosed wooden crate which has been properly prepared for overseas shipments.
If your new MSI Well Service Pump, as packaged from MSI, will be in storage for longer than one
month, then the following preservation measures should be taken:
Inspect the unit.
Look for any condensation or accumulation of water inside the shrink wrapping which could indicate a
broken seal or depleted desiccant. Remove and dry out any water found inside the packaging and
replace the desiccant if necessary. Reseal the moisture barrier using sheet plastic and duct tape.
Keeping the unit out of moisture or away from salt spray is helpful.

If the unit has been in service and will be stored for more than a couple of weeks, remove the cover
