High-pressure Pump; Accumulator Tank; Electrical Solenoid; Pressure Switch ; Misting Nozzles; The High-Pressure Water Pump. Accumulator Tanks can offer even more flow than an inline pump, delivering up to 36 litres per minute. Diaphragm pumps act as their own one-way valves and often contain a pressure switch. Legally, the water undertaker only needs to supply a minimum of 1 bar pressure and 9 litres per minute flow rate, at the suppliers stop tap. How to check if a system is negative head –, To check if your gravity-fed system is negative head carry out this simple test. Microswitched systems dispense with the pressure switch and accumulators. This helps prevent rapid pump on/off cycling and helps to prolong the life and performance of the pump. Accumulators act like a giant pressure vessel with two chambers – one that’s pressurised with inert gas and sealed, the other that’s open to your water system. Accumulators are an ideal solution for properties where the mains water supply cannot keep-up with the required demand; this is often the case with larger properties where multiple bathrooms may be in-use simultaneously. Also fluctuating shower temperatures whenever another outlet is used. You cannot pump the output of a Megaflo Unvented system, so the solution needs to be applied upstream of the unvented cylinder.
