White Star's quadraplex mud pump has its bearing placement between cylinders, which creates a more stable design, reducing load and flexing of the frame and crankshaft.

Drilling Contractor visited the manufacturing facility of White Star Pump Company in Waller, Texas, on 17 February to view a demonstration of the company’s quadraplex mud pump, which was designed to address the challenges of the conventional triplex pump.

“After working on all the different brands of (triplex) pumps, it became evident that they all had the same common issues,” said Bruce Suggs, vice president of marketing and sales for White Star. “(We) tried to build a triplex and ended up with the Quatro.”

Instead of taking an existing triplex pump and trying to make it better, White Star approached the project with a clean-sheet design. The Quatro pump features a width of only 82 in. and easily fits on a standard-width trailer, a potential advantage in areas with limited space, such as on offshore rigs and in shale plays like the Marcellus. With the fluid modules sitting inside the frame, change-out time can be reduced to 23 minutes versus up to 10 hours for conventional triplex pumps. The quadraplex pump also uses a fully assembled crankshaft that requires no castings or welding. Using a crankshaft that is fully assembled and supported by modern bearing placement dramatically reduces crankshaft bending and cracking.

Additionally, the Quatro is equipped with two pulsation dampeners, one for each pair of pistons, unlike the triplex, which carries only one. This allows mud to be dampened before it gets to the strain across, creating a quieter, smoother fluid flow and reducing vibrations.

    I will greatly appreciate if you can send me some more technical and operational details about this Quad pumps vs conventional triple cyl pumps.

    Thanks.
