Did you know that current pressure applications within  hydraulic Pumps  systems stem from a principle developed nearly 370 years ago? French scientist Blaise Pascal first came up with an idea in 1653 that became called Pascal’s Law, a principle that allows large forces to be created with relatively little effort. The law is often explained in different ways, but it can be summarized as “When pressure is applied to an incompressible fluid, the pressure is the same in all directions”. Pascal’s law remains an important fundamental element in determining the use of compressible fluids (such as oil or water) in hydraulic systems to transfer forces from one location to another within that fluid. Pascal’s findings remain fundamental to understanding fluid pressure transmission in all hydraulic systems. What is Pascal’s law? Pascal (1623-1662) was a French mathematician, physicist, and philosopher known for developing modern probability theory. He also formulated the concep...

Hydraulic pump  cavitation is a devastating problem. It is the likely cause of symptoms such as excessive noise, energy use, pump damage, and pump failure. Although each of these symptoms can indicate other concerns, cavitation is one of the most troublesome, as it can compromise the entire hydraulic system. It is the second leading cause of hydraulic pump failure behind hydraulic fluid contamination. For this reason, let’s look at some of the causes of cavitation, how to recognize its occurrence, as well as how to prevent damage and keep hydraulic systems healthy. What is cavitation and what causes it on hydraulic pumps? Cavitation occurs from the formation of vapors and the resulting breakdown inside the  hydraulic pump . Excessive vacuum conditions on the inlet (supply) side of the pump create steam bubbles within the hydraulic fluid which then travel to the discharge (pressure) side, at which point they collapse. The moment of collapse is when cavity damage occurs....

The hydraulic parts exporter specializes in four production lines: Vickers, Denison, Rexroth hydraulic pump series, servo valves and proportional valves. HPS is proud to offer Vickers products, which offer an incredibly diverse range of applications and enduring quality. Known for their vibrant blue color, Vickers hydraulic components are one of the oldest known names in fluid power. With over two million hydraulic parts on the shelf, HPS has the largest inventory availability of obsolete, discontinued, long-lasting and hard-to-find Vickers products. What is Vickers? Or rather... Who is Vickers? Vickers hydraulics are named after a man considered the "father of industrial hydraulics", Harry Franklin Vickers (1898 - 1977), an American industrialist and inventor from California. After returning from his time serving in the US Army Signal Corps during World War I, he founded the company that became the brand: Vickers Manufacturing.   The company, later known as Vi...
