Product Conformity
The performance of the double suction pump has been fully optimized to meet the four key requirements of the American Fire Protection Standards FM/UL.
1) The performance meets the requirements of rated flow and rated pressure.
2) The outlet pressure at zero flow does not exceed 140% of the rated pressure.
3) At a suction depth of 4.6 meters, when the flow is 150% of the rated flow, the outlet pressure should not be less than 65% of the rated pressure.
4) The performance curve includes a maximum shaft power value, and the driving power provided exceeds this maximum shaft power value.
Materials conform to standard
1) pump case and pump cover: Ductile Iron
2) Impeller: Brass/ SS304
3) Wear ring: Brass/ SS304
4) Sealing: Gland packing/ Mechanical Seal
APPLICATION
