We simply subtract the two values (133 psi - 30 psi = 103 psi). This is the amount of pressure the booster pump system will need to deliver in order to provide adequate pressure to the building. Next, we convert the 103-psi boost requirement value into feet by multiplying by 2.31.
A single VFD can be used in a basic lead-lag system to regulate pressure by directly controlling the lead pump motor's speed, while turning the lag booster pumps on and off through each pump's across-the-line starter (See Figure 1). This scheme uses the VFD's discrete outputs (dry output relays) to control each booster pump's motor contactor.
The MHI/MHN series are cost competitive, horizontal, multistage, non self-priming, close coupled centrifugal pumps. Flow range: 0.5 - 28 m³/h. Head range: up to 77 metres. Rating: 0.37 kW to 7.50 kW.
