7 Some Lies About Hydraulic Pumps

1. "This pump will never fail": No mechanical component is immune to failure, including hydraulic pumps.

While a high quality pump and proper maintenance can significantly reduce the risk of failure.

It is unrealistic to claim that a hydraulic pump will never fail.

2. "This pump will double the efficiency of your system": while upgrading to a more efficient hydraulic pump

can improve the efficiency of the entire system, it is unlikely that a single component will make the entire system more efficient.

efficiency of the entire system. Efficiency improvements usually require a comprehensive approach that includes a

a variety of factors such as pump selection, system design, control strategy and proper maintenance.

3. "This pump requires no maintenance": All hydraulic pumps require regular maintenance to ensure

optimum performance and service life. While some modern pumps may have extended service life

intervals or improved reliability characteristics, routine inspections, lubrication checks,.

and other maintenance tasks are still necessary for optimal operation.

4. "The pump is completely noiseless": Hydraulic pumps inherently generate noise due to fluid flow

and mechanical components in operation. While technoLogical advances have led to quieter designs

and noise reduction measures that claim to be completely noise-free may not be accurate.

It is important to critically evaluate claims about hydraulic pumps and consult reliable sources

or experts when evaluating their suitability for specific applications

or resolving issues related to performance or reliability.

5. "All hydraulic pumps are created equal": Different hydraulic pump designs (gear, vane, piston, etc.) have their own strengths and weaknesses. 

Choosing the right pump for the specific application is crucial. A high-pressure pump might be overkill for a low-pressure system, while a low-flow pump wouldn't be suitable for a system requiring high force.

6. "Hydraulic fluid doesn't matter": The type and quality of hydraulic fluid significantly impacts pump performance and lifespan. 

Using the wrong fluid can lead to increased wear, reduced efficiency, and even pump failure. Choosing the correct viscosity and contamination level for the specific pump and operating conditions is essential.

7. "Bigger is always better": While a larger pump might seem like the answer to needing more power, it can actually be detrimental.

 An oversized pump will consume more energy, generate unnecessary heat, and potentially cause cavitation (formation and collapse of vapor bubbles) which damages components. Selecting the right pump size for the required flow and pressure is key.
