Pump Applicant  

GDL are the products of multiple functions, applicable for transporting various different media from tap water to industrial liquids and suitable for different ranges of temperature , flow and pressure .

GDL is applicable for non-corrosive liquids while GDLF for lightly corrosive ones.

Water supply: filter and transportation and quartering water feed for water works, boost for main pipes and high buildings.

Industrial boost: flowing water system, cleaning system, high pressure rinsing system, fire fighting system.

Industrial liquid transportation: cooling & air-conditioning system, boiler water supply & condensing system, completion of machine tools, acid and alkali.

Water treatment: extra-filter system, reverse osmosis system, distilling system, separator, swimming pool.

Irrigation: farmland irrigation, sprinkler irrigation, trickle irrigation.

Part of Sample Project

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.
