If we want to know the application of a slurry pump well, we have to know some terminology first. Now let's learn them together,
A mathematical relationship between head, flow and power, which enables pump performance to be determined as the speed or impeller diameter is altered.
The volume of liquid to be transported in a unit time.
Concentration by mass
The solids present in a two-phase mixture expressed as a percentage of the mass of the total mixture.
Concentration by volume
The solids present in a two-phase mixture expressed as a percentage of the volume of the total mixture.
The mass of a fluid as expressed in its mass per unit volume (kg/m3).
The ratio of energy delivered by the pump to the energy supplied to the pump shaft, expressed as a percentage.
Alternative terminology for capacity, quantity or volume to be pumped.
A fraction or portion of the mixture, which is represented by a small screen sizing.
The resistance to flow normally associated with pipes and fittings which is a function of the pipe diameter and the rate of charge of flow.
Rate of flow in a given direction, e.g. m/sec.
A portion of the casing through which the shaft extends which holds packing material to prevent leakage.
System Head Curve
A curve showing the relationship between the total head required by the system to produce a given flow.
Net positive suction head. The total suction head in absolute units at the impeller centerline less the absolute vapour pressure of the liquid.
A lubricated fiber type material used to provide a seal around the portion of the shaft in the stuffing box.
