In essence  the term piggyback is when your using multiple pumps that are assembled or combine on one drive shaft. And the pump numbers listed above are usual for these pumps. Usually you will have a smaller section in the front and middle with the larger one in the back. You have different reservoirs and different fluids pumped into a piggyback system, with no worry of mixing fluids.

And the way the piggybacks are made will deliver greater outputs and efficiency. The most common uses of piggybacks are on utility vechiles, front end loaders and shovel loaders.

QX double pumps consits of two single pumps mounted on a common drive shaft. Hydraulically, the two pumps operate independently of one another but they share a common suction port in the pump´s centre section. The larger pump of the combination is situated at the shaft end (the drive side). With equal frame sizes, the pump with the larger displacement is situated at the drive side.

We provide hydraulic components & repair services for industrial applications like paper mills, saw mills, steel mills, recycling plants, oil & gas applications and mobile applications, including construction, utility, mining, agricultural and marine equipment. This includes hydraulic pumps, motors, valves, servo/prop valves, PTOs, cylinders & parts.

The SPD2 series of pumps are special SP-25A series pumps with through shafts. The through shafts have 9 tooth internal splines at the rear and the pump’s rear cover has an integral SAE A-2 bolt mount pad. For double pump operation, a standard SAE A-2 boltsplined shaft pump can be directly mounted on the rear on the SPD2. Typical performance of the pump is the same as indicated for the SP-25A series pump.

Originally established in 1972, we have seen continuous growth over the last 43 years at Hyseco, Inc. This has included multiple expansions, culminating in our full-service hydraulic gear pump and motor facility in the 1990s.

UNITS WERE ASSEMBLED AS PART OF A HYDRAULIC TOP DRIVE POWER SYSTEM AND NEVER PUT INTO SERVICE. UNITS HAVE BEEN IN STROAGE FOR OVER 8 YEARS IN AN ENCLOSED SKID.

Piggy-back cylinders, as the name implies, are two opposing hydraulic cylinders mounted with the bodies on top of each other. Taking advantage of this configuration enables a longer stroke from a relatively short overall length. They’re somewhat similar to familiar telescoping cylinders, where several cylinder stages are built inside of one another, and the unit features relatively short retracted length but long extended length. But when only two stages are required, a piggy-back cylinder can be a simpler and more-economical alternative.

Piggy-back cylinders from Texas Hydraulics, Temple, Tex., are made of two rod cylinders with the barrels welded or bolted together. They’re designed for applications with limited mounting space that require a long extended length and a short retraction length. They provide consistent force and speed, and they’re suited for low and high-pressure applications.

Usually, the two cylinders have the same bore and stroke, and only one hydraulic line each is needed for extension and one line for retraction. This simplifies plumbing and limits potential leak points. Units with the same bore sizes also have interchangeable seals.

Optional features include rod or tube porting, integrated valving and built-in cushions. Piggy-back cylinders can also be designed for sequencing and multiple stopping points. For instance, by specifying a different stroke for each cylinder, and adding hydraulic lines for each, four different positions can be controlled: when both cylinders are retracted, when only the first cylinder extends, when only the second extends, and when both cylinders extend.
