Performance parameters of slurry pump


Release time:

Jan 30,2023

The added value of energy after the unit weight liquid passes through the slurry pump is equal to the algebraic difference between the outlet head of the slurry pump and the total inlet head, in meters of water column (mH2O), that is, the conveying height of the slurry pump.

Performance parameters of slurry pump

1、 Flow
Flow: refers to the amount of liquid discharged by the slurry pump per unit time, which can be expressed in two ways, namely, volume force Q and mass flow Qc
Unit of volume flow "m ³ h”、“L/S”
Weight flow unit "t/h", "kgf/h"
The relationship between volume flow and weight flow is: Qc=YQ
Y is the specific gravity (gravity) of the slurry kgf/m ³
2、 Lift
The added value of energy after the unit weight liquid passes through the slurry pump is equal to the algebraic difference between the outlet head of the slurry pump and the total inlet head, in meters of water column (mH2O), that is, the conveying height of the slurry pump.
3、 Speed n
Indicates the number of revolutions per minute of the slurry pump shaft, in r/min
4、 Power
The power of slurry pump includes:
Output power Pe: the work done on the fluid flowing through the pump in unit time.
Input power P: refers to the power delivered by the motor to the pump shaft.
Matching power Pg: the rated output power of the motor. Generally, the matching power is larger than the shaft power.
5、 Efficiency
The difference between the input power and output power of the pump is the ratio of the power loss in the pump.
