Premium Oilfield Supply, Ltd

The Nitrile Rubber Bonded piston was designed for use with water-based muds. It is particularly suited for situations where a driller needs to get extra life from a liner that is already worn to a larger ID. Best for temperatures up to 220°F

• SeriesX-7500,

The Single Piece Valve-Over Valve fluid end was designed by our engineers to weigh less and take up less space around the drilling rig, making it easier for in-field conversions to 7500 psi. Additionally, this design uses components that are 100% interchangeable with other manufacturers’ components as well as our own 2-piece fluid end design. Available for the following 1600hp and above pumps: Continental Emsco Gardner Denver Ideco National Oilwell Lewco Features and Benefits: Fluid energizing seal Metal-to-metal seal on valve cover 2 pitch acme style threads on valve cover & liner retention systems Engineered to reduce internal loads on valve cover and mud flow areas Replaceable liner wear plate Designed with rear mount manifold for easy module replacement

• SeriesF-1600

This single piece design is compatible with fluid ends from most manufacturers and uses industry standard components. Also stocked for other F-series pumps.

RPM on Packing Seals Reduced A planetary gear is integrated into the lower housing. The carrier holds the washpipe and by design rotates 40% slower. This allows the rotational speed to be split 6040 between lower and upper housings. This raises the Pressure-Velocity values for your existing seals which increases seal life. Self Aligning The Sur-Drive cartridge assembly has a unique feature for self-centering during installation which compensates for lateral misalignment between the gooseneck and main shaft pilots. Hammerless Installation The Sur-Drive cartridge assembly can be inserted horizontally and secured into place with two hub clamps by permanently installing our adapter hubs. Sealed Gear Box All gear box components are submerged in gear oil which provides constant lubrication and eliminates the need for costly, space consuming roller bearings. Rotary shaft seals are used to keep the oil in, and the dirt out. Pre-Compressed Packing Seals The Sur-Drive cartridge assembly allows for the seals to be compressed on the ground prior to installation by way of eight low torque screws. No special tools are needed to compress these seals. Competitively Priced Our true through-bore versions do very well versus ceramic seal based washpipe assemblies costing tens of thousands of dollars more.

• SeriesSG

The SG Standard Service piston was designed for drilling applications with mud temperatures under 180°F. Designed for oil-based and synthetic muds Medium pressures and low pressure up to 4500 psi

Premium Oilfield Technologies carries complete cartridge assemblies for the major brands of top drives and swivels. We recommend carrying an extra assembly on standby for quick turnaround and reduced downtime. Our washpipes are chrome plated and ground to a fine finish ensuring a tight seal and reduced friction. Washpipe packing is molded using rubber impregnated fabric to increase durability and longevity. All of our parts are interchangeable on a part-to-part and unit-to-unit basis.
