Learn all about hydraulic pumps and hydraulic pump repair
A hydraulic pump is unique in that it does not require an external power source, be it electricity or petroleum fuel, to move standing water from point A to point B. All hydraulic pumps draw on the physics principle of inertia: objects in motion tend to stay in motion (while objects at rest tend to stay at rest).
These machines, whether they are powerful hydraulic ram pumps or compact hydraulic hand pumps, work by putting the standing water in motion. Once it's in motion, it will tend to stay in motion, and the liquid will essentially work to pump itself.
How Hydraulic Pumps Work
There are two key phases in a hydraulic pump's cycle. The first is the forcing of water into the pump's tubes, which builds up pressure. When even small airways are introduced to these tubes, the under-pressure water begins to accelerate. A check valve monitors the amount of pressure and momentum building up in the system, and when it reaches its maximum, it opens and the water is forced out of the system.
This is when the second phase begins. The water coming out of the hydraulic pump's tubes needs a place to collect, and it is forced into a tank. These tanks vary in size, from small ones designed to tackle minor jobs to large ones that can handle much bigger tasks.
Hydraulic Pump Maintenance and Repair
Given that hydraulic pumps rely on internal rather than external power, they have fewer working parts that can break down. This is one way in which they vary significantly from pumps such as diaphragm pumps. However, the check valves are parts that get a lot of use. Over time, they will wear down, and at this point you may require hydraulic pump repair.
If you notice that your hydraulic pump is not performing optimally, don't delay repairs. Initial signs of wear can signal the potential for larger underlying problems, so you should seek hydraulic pump repair at the earliest possible juncture to head off any possibility of needing to replace your system in its entirety.
