The number of pumping devices to pump fluid in a pool depends primarily on how much water is available and how complex the pool system is. It also affects whether there are special areas. We are talking about fountains, SPAs, whirlpools, sports areas, and attractions. Each of the above devices has its special features. Pumps without specific functions, which are traditionally used to carry out service work in the pool, are divided by the principle of action – on the centrifugal and vortex.
