Pump model parameters are identified with the following letters: flow =m3\/h, head =m, revolution =r\/min, working pressure =MPa, motor power =KW, working temperature =℃, efficiency =%, cavitation allowance =m
And various pump model interpretation is not the same, the following examples for reference;
Such as sewage pump series model significance
Q: diving W: blowdown G: Pipeline Y: liquid N: mud Z: self-priming L: vertical
AS: torn JY: mixed P: stainless steel B: explosion-proof
QW (WQ) non-clogging submersible sewage pump
For example, run the 80WQ (QW) P40-15-4 command
80 WQ(QW) P 40 - 15 - 4

one
Flow rate (Q) The flow rate of the pump is the amount of liquid discharged per unit time. Usually pump flow using the volume calculation, expressed as a Q, the unit is m 3 \/ (m3 \/ h), 3 m\/SEC (m3 \/ s), l\/SEC (1 \/ s), also can use weight, in G, said units for t\/(t\/h), t\/s (t\/s), kg\/SEC (kg\/s).
two
Lift (H) The lift of a pump is the amount of energy added per unit weight of liquid through the pump. Expressed in H, it is essentially the height at which the pump can lift water, also known as total lift or full lift. The unit is the height of the liquid column in meters, and it is customary to omit the \"liquid column\" and express it in meters (m).
three
Allowable suction vacuum height (Hs) Allowable suction vacuum height refers to the suction head reading of the vacuum gauge, that is, the suction of the pump
