Main Purpose
- MSseries of product is widely used for water plant, irrigation, drainage pumping station, power station, water circulation of air-
conditioning, industrial water supply system, fire system and shipping industry as well as for the general purpose in the oil refining
industry.

Hydraulic performance
- It adopts the internantional advanced computer aided software and the modern design methods(namely optimum design and reliable
design approach) for the hydraulic and structural design of the pump so that MS double-suction pump boasts efficient and noticeable
resistance to cavitation. Compared with home-made like products, this series of product has a 2-4% higher efficiency and noticeably
stronger cavitation resistance, which will save a lot of capital for the user.

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 MS 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°C
