Head pressure is the simplest way of stating the max operation pressure of a pump. 11m of water is equal to 15.6 psi. There are conversion calculators online. That means that the pump can withstand a total pressure drop(really total system pressure) of 15.6psi before it stalls.
- NOTE: This head pressure threshold has to cover not only fighting gravity pushing liquid straight up (which is how it is often described online) but also the friction and resistance of the entire rest of the cooling loop.
Pumps in series or parallel are very similar to the way batteries work. 2 pumps in parallel will double your flow rate but will not greatly increase the amount of pressure the system can handle. 2 pumps in series will double(roughly) the pressure the system can handle but your flow rate will stay about the same.
