      Can somebody please help in understanding the difference between pressure compensated variable displacement pump circuit and load sense? Below is my understanding:

      VD Pressure compensated Pump circuit: You can not control flow rate unless the pressure compensator pressure setting is achieved. After which pump flow can be controlled while pump maintaining that maximum pressure.

      Load Sense Pump Circuit: Firstly, We can control flow rate by regulating needle valve or proportional valve that is downstream of pump to get required actuator speed without reaching maximum pressure compensator setting. Secondly as the load changes the pump adjusts valve upstream pressure to maintain the flowrate across the valve (which we adjusted before to get required actuator speed).

      Is my understanding right? Kindly explain in simple terms if you can. Thank you in advance [​IMG]

      When I found Dr.wadada I was in desperate need of bringing my ex lover back. He left me for another woman. It happened so fast and I had no say in the situation at all. He just dumped me after 3 years with no explanation. I contact Dr.wadada through his website and He told me me what i need to do before he can help me and i did what he told me to, after i provided what he wanted, he cast a love spell to help us get back together. Shortly after he did his spell, my boyfriend started texting me again and felt horrible for what he just put me through. He said that I was the most important person in his life and he knows that now. We moved in together and he was more open to me than before and he started spending more time with me than before. Ever since Dr.wadada helped me, my partner is very stable, faithful and closer to me than before. I highly recommends Dr.wadada to anyone in need of help.
