WebDec 9, 2024 · These factors include Flow, Head, Efficiency, Impeller Trim Diameter, NPSHR, Power, MCSF (Minimum Continuous Stable Flow), and RPM. The Pump curve also represents the Pump model, the Pump size, and the number of stages for multi-stage pumps. The Pump curve displays the Flowrate range on the horizontal axis. WebCorrosion-Resistant Dewatering Pump for High Head. A tried-and-true dewatering pump with boosted double hydraulics. This new performer is designed for pumping at ultra-high …
WebFor flows in the range of 25–99 gpm, an approximate efficiency can be obtained by solving Eq. (5-5) for 100 gpm and then subtracting 0.35% gpm times the difference between 100 gpm and the low flow rate in gpm. For low flow rates, near 25–30 gpm, this will give results within about 15% for the middle of the head range (pump AP) and 25% at ... WebJul 29, 2024 · Measured in gallons per minute (GPM), the flow rate of a pump refers to the maximum volume of water it can circulate at a given head range. • The head range is …
WebAnswer (1 of 2): It probably means the shut off head of the pump is 30m, i.e the pump can pump the liquid up to a maximum height of 30m (neglecting all other resistances). Note: At shut off head, a pump virtually has zero discharge, meaning that when it is pumping to 30m it is supplying just eno...
