OS type pump is an axial split-stage single-stage double-suction horizontal centrifugal pump. It is mainly suitable for transportation from water plants, air-conditioning circulating water, building water supply, irrigation, drainage pump stations, power stations, industrial water supply systems, fire protection systems, shipbuilding industry, etc. Liquid situations.
This model of pump adopts linear design, compact structure, beautiful appearance, good stability and easy installation.
The double-suction impeller reduces the axial force, has excellent hydraulic performance, good rigidity and small vibration. Mechanical seal or soft packing seal can be selected. The pump body adopts a double volute structure with small radial force, which increases the life of wearing parts.
