Choosing pumps should make water pump nameplate on the head with the best head needed close to such a case, the pump efficiency is highest, use will be more economic. But not necessarily demands absolute equal, general deviation as long as no more than 20%, the water pump can be in the energy conservation work.

more than 2, nameplate, head is good?
