Back Pressure

Back pressure refers to the pressure against which the pump delivers liquids or gases. It is the pressure the medium being pumped exerts on the pump as it exits. Back pressure can manifest itself in different ways depending on the pump used. 

A low back pressure means the pump is pumping against a low resistor, while a high back pressure means the pump works against a strong resistor. The back pressure can depend on various factors, including the height to which the medium needs to be pumped, the friction in the piping and other components of the system, and the viscosity of the medium. It is essential to consider backpressure when selecting and operating pumps, as it affects the pump's performance. If the pump has to work against high back pressure, it needs more energy to deliver the medium, which can reduce the pump's efficiency. It is, therefore, important to monitor the back pressure to ensure the pump works optimally and achieves the desired flow rate.
