Structural Features:
1. Compact structure, space effective and much shorter axial dimensions.
2. Small vibration and low noise, achieved mainly by means of the follow:
A. The pump casing adopts the double-volute structure;
B. The rotor part has short axial dimensions and a good rigidity.
C. The pump shaft adopts the imported high-precision bearing for the support.
Working Conditions:
The maximum working pressure of volute double-suction pump system is 2.5Mpa, namely pump inlet pressure +pump lift head≤ 2.5Mpa, and the test pressure of pump static pressure is 3.75Mpa. According to the maximum pressure that the pump body can bear, the materials for body and bonnet adopt the grey cast iron(1.6Mpa), spheroidal graphite cast iron(2.0Mpa)and cast steel (2.5Mpa). Please note the pump's bearing pressure or materials in the order. This series of pump can transport the clear water or other liquids with similar physical and chemical properties as clear water with temperture T≤ 105 deg C.
Type Designation:
300 - 450(I)A
300 - diameter of pump outlet (mm)
450 - nominal diameter of impeller (mm)
I - Flow classification
A - rimary cutting of impeller
