Product Description
GDL non-self suction vertical multi-stage centrifugal pumps mounted with a standard motor, the motor shaft is linked, via the motor seat, directly with the pump shaft with a clutch, both pressure-proof barrel and flow-passing components are fixed in between the motor seat and the water in-out section with pull-bar bolts and both water inlet and outlet of the pump are positioned on one line of the pump bottom; and the pumps can be fitted with an intelligent protector, in case of necessity, to effectively protect them against dry movement, lack-of-phase, overload etc.

CURVE
The description below is applicable for the curves shown on the back:
1. All the curves are based on the values measured at the constant speed of 2900rpm or 2950rpm of the motor.
2. The allowed curve differences comply with ISO9906, Appendix A.
3. The water at 20 containing no air is used for the measurement, the moving viscosity of it is 1mm /s.
4. The pump shall be used within the performance range shown by the thickened curves so as to prevent against overheat due to an undersized flow and prevent the motor against overload due to an oversized flow.
