When opening the tap water from the accumulator enters the network and compensates for the sharp drop in pressure. The larger tank capacity, the less often the pump. Sales can be found accumulators with capacity from eight to several hundreds and even thousands of liters. I must say that cheap vosmilitrovye tanks not adequately cope with their problems. Thus, the draw-point (kitchen faucet, shower, dishwasher, etc.) spends from six to fifteen liters per minute, so the only missing eight liters for 15-30 seconds of a particular device. Practice shows that the optimal solution for a country house is to buy 25 – or 50-liter accumulator (cost 50-100 USD). Important operating parameters of pumping stations are the compactness of the equipment and quiet of his work.
Good performance in complex series of mq (Grundfos): their overall size is just 57x22x32 cm This mini-station will fit even on the kitchen shelf. Quiet Operation depends primarily on the design of the pump (centrifugal pump is much quieter than the vortex) and the method of motor cooling (fan or air pumped liquid). Thus, the pump motor mq cooled by water, which provides a lower noise level. Nevertheless, the leaders are pumps 'glandless' (for example, a series of chie, Grundfos). Without water, appliances can overheat and fail, so safe work in such equipment used protection from 'dry run'. This option have a series jexm (Ebara), bgm (Lowara), ngc with the automation unit brio (Calpeda), station mq (Grundfos), mcx (Nocchi), Wilo-Jet fwj (WILO) and Hydrofresh (Pedrollo).
