What happens when the intake pipe of a hydraulic pump is not sealed properly?

When the intake pipe of a hydraulic pump is not sealed properly, the pump is unable to maintain the necessary vacuum or pressure to draw hydraulic fluid from the reservoir effectively. This leads to an insufficient supply of fluid entering the pump, which directly impacts its performance.

As a result, the hydraulic fluid may not flow into the pump as intended, causing a decrease in the pump's output. In hydraulic systems, proper sealing is crucial for ensuring that fluid is moved efficiently and effectively. If air is allowed to enter the system through an unsealed intake, it can create cavitation or introduce inconsistencies in the fluid flow, further diminishing the pump's ability to deliver the required pressure and flow rate.

Overall, this compromised intake seal is detrimental to the hydraulic system's operation, causing the output to decrease significantly.
