DFG (DFRG) series of single-stage vertical pipeline centrifugal pump
First, the product overview
DFG (DFRG) series single-stage single-suction vertical pipeline centrifugal pump is a direct-connected pipeline pump structure. The impeller is mounted on the motor extended shaft, which has the advantages of stable operation, simple structure, easy maintenance and repair, convenient installation and area saving Horizontal pump than the floor area savings of more than 30%) and other characteristics; products meet the GB / T5657-1994 "Centrifugal Pump Technical Specifications (III)" standard; transportable medium temperature does not exceed 105 ℃ water or physicochemical properties similar to Other liquids in clear water.
Second, the product features
1, energy-efficient: The CFD computational fluid dynamics, analysis and calculation of the pump pressure distribution and velocity distribution, optimize the pump flow channel design, to ensure that the pump has an efficient hydraulic shape line, improve the pump efficiency.
2, easy installation and maintenance: vertical pipe structure, the import and export of the pump can be installed in the pipeline as any position and any direction, installation and maintenance is very convenient.
3, smooth operation, safe and reliable: Motor shaft and pump shaft for the coaxial straight, high concentricity, stable operation, safe and reliable.
4, stainless steel sleeve: shaft seal location is relatively easy to rust, direct-coupled pump shaft once corroded, easy to cause mechanical seal failure. DFG (DFRG) pumps are fitted with stainless steel bushings to prevent rusting, improve shaft life and reduce operating and maintenance costs.
5, Bearing: pump equipped with motor, Y (Y2) 280 below the shaft end bearings (including Y180 the following blade end bearings) with closed bearings, normal use, maintenance-free motor bearings.
6, mechanical seal: mechanical seal base member is generally used rubber bellows structure, the traditional mechanical seal shaft seal by the O-ring seal into two parts of the rubber seal, sealing water in the media to improve the sealing effect.
