pumps where smaller ones will sufficient. High capacity pumps have other applications, such as those using large vacuum chambers, but in a smaller refrigeration circuit, a 100 m3/h pump will generate only 30% more pumping capacity at 5 times the size of a 20 m3/h pump. In business language, that is a poor return on investment.
