Denison's innovative beginnings are shown in the quality of flexible parts

The Rexroth hydraulic pump exporter specializes in four product lines: Vickers, Denison, Rexroth A10VSO series, servo valves and proportional valves. Part of a series on the origins of each of the major hydraulic brands we offer, we focus on Denison Hydraulics in this article.

Denison's high-quality flexible products have a reputation for standing the test of time and being particularly useful when applied to a variety of mobile and industrial applications.

Denison has a long history of innovation, beginning with the emergence of hydraulics and continuing through tough economic times as a leader in new and versatile products.

HPS' comprehensive line of Denison products includes pumps, motors, valves and servomotors/proportional parts of this power. These products continue to provide the versatility and quality needed to recycle year after year.

Who is Denison?

Denison Hydraulics Inc. It is owned by Parker Hannifin and is based in Marysville, Ohio.

With revenues of approximately $180 million, the Rexroth pump manufacturer has 1,150 employees in North America, Europe and Asia.

Denison Hydraulics serves the global market with reliable hydraulic equipment and systems for mobile, industrial, power, defense and marine applications.

And while the manufacturer has gone through some tough times in its 120-year history, Denison remains the world's preferred choice of hydraulic products for applications that demand high performance, reliability and flexibility.

Original origin

Founded in 1900 in Delaware, Ohio as the Cook Motor Company, Denison manufactures heavy-duty industrial single-cylinder gasoline engines only.

After World War I, Bill Dennison acquired the Cook Motor Company while the motor market was dying.

But Denison had the idea ofdeveloping a machine designed to slowly move clay-filled wagons through the kiln. It was the first hydraulic machine and the beginning of a long history of innovation.

The advent of hydraulics, called Hydraulics’ at the time, helped keep the company going through tough times. (If you have time, Google the word "Hydraulics’" and you might find some operable machines approaching their 100th birthday.)

Cook Motor Company went into receivership and reorganized into Denison Engineering during the Great Depression. They continue to innovate with products such as the rail pusher and the "compact" power unit.

Denison hydraulics: truly unparalleled quality

Today, Denison's well-designed, competitive products are among the products that hold up well in the remanufacturing process and can easily be brought back to life with the help of HPS.

Its impressive and successful 120-year history of innovation and longevity leaves no mystery as to why Denison is the preferred hydraulic brand worldwide, and the preferred choice here at HPS.

Of the more than two million HPS Rexroth Motors on the shelf, Denison products continue to lead with high performance, reliability and flexibility that stand the test of time.

Types of hydraulic pumps

There are generally three types of hydraulic pump structures found in mobile hydraulic applications. These include gears, pistons and blades. However, there are also clutch pumps, vacuum pumps, and dump truck pumps, such as Muncie Power Products' Dry Valve Pumps and Live PakTM.

A hydraulic pump is a component of a hydraulic system that takes mechanical energy and converts it into fluid energy in the form of an oil flow. This mechanical energy is taken from what is called the main engine (rotational force) such as the PTO or directly from the truck's engine.

With each hydraulic pump, the pump will be of either a single-rotor or two-role design. As its name suggests, the single-rotating pump is designed to operate in one direction of shaft rotation. On the other hand, a bi-circulating pump has the ability to work in any direction.

Gear pumps

For truck-mounted hydraulic systems, the most common design in use is a gear pump. This design has fewer moving parts, is easier to maintain, is more tolerant of pollution than other designs, and is relatively inexpensive. Gear pumps are fixed displacement pumps, also called positive displacement pumps. This means that the same volume of flow is produced with each rotation of the pump shaft. Gear pumps are rated for maximum pump pressure rating, displacement in cubic inches, and maximum input speed.

Gear pumps are generally used in open center hydraulic systems. Gear pumps trap oil in the areas between the pump gear teeth and the pump body, move it around the circumference of the gear bore, and then force it out through the outlet port when the gears are engaged. Behind the copper alloy drive plates, or wear plates, a small amount of pressurized oil pushes the plates firmly against the gear tips to improve pump efficiency.

Piston pumps

When high operating pressures are required, piston pumps are often used. Piston pumps traditionally withstand higher pressures than gear pumps of similar displacement; however, there is a higher initial cost associated with piston pumps, as well as lower resistance to contamination and increased complexity.

The equipment designer and service technician must understand this complexity to ensure that the piston pump operates correctly with its additional moving parts, stricter filtration requirements, and stricter tolerances. Piston pumps are often used with truck-mounted cranes, but they are also found in other applications, such as snow and ice control, where it may be desirable to vary the flow of the system without changing the engine speed.

A cylinder block containing pistons that move in and out is located inside a piston pump. It is the movement of these pistons that pulls the oil from the supply port and then pushes it through the port. The angle of the discontinuous plate, against which the sliding end of the piston slides, determines the length of the stroke of the piston. While the powder plate remains stationary, the cylinder block, which includes the pistons, rotates with the pump's input shaft. The pump displacement is then determined by the total volume of the pump cylinders. Fixed and variable displacement designs are available.
