Product Details
Overvie
The DFG series (with hot - water types derived from it) of pipeline
pumps is carefully designed by our company using hydraulic models
and according to the needs of various users under different
operating conditions. The product quality complies with the
standard GB/T 5657 - 1995 Technical Conditions for Centrifugal Pumps - Class III.
For the DFG series pipeline pumps, the direct connection between
the motor and the pump simplifies the intermediate transmission
structure and enhances the running stability. With a pipeline -
type structure, the inlet and outlet of the pump can be installed
at any position and in any direction of the pipeline, just like
valves. Compared with ordinary horizontal pumps, it reduces the
floor space by 30%. It also features low running noise and small
vibration, significantly extending the service life of vulnerable
parts. This type of pump is widely favored in the market for its
stable performance, energy - saving feature, small footprint, and
compact structure.
Applications
- Suitable for industrial water supply, urban water supply, and water
supply for high - rise buildings.
- For boosting pressure in fire - fighting pipelines.
- For the circulation of hot and cold water in air - conditioning
systems.
- For long - distance water transportation.
- For circulation, boosting, and transportation in the production
process, and also suitable for use with various water supply and
drainage equipment, boilers, etc.
Operating Conditions and Scope
- The volume of insoluble solids in the suction and discharge medium
should not exceed 1% of the total volume, and the particle size
should be ≤ 0.2mm.
- Flow range: 2 - 1400 m³/h.
- Head range: 5 - 130 m.
- The maximum working pressure of the pump system should be ≤ 1.6MPa,
that is, the suction port pressure + the pump head ≤ 1.6MPa.
- When the inlet pressure is greater than 0.8MPa, the materials of
the pump body and pump cover need to be changed, such as ductile
iron QT450 - 10.
- Medium temperature: -15ºC < T ≤ +80ºC. For hot - water types,
80ºC < T < 105ºC. Special orders are required when the
temperature is equal to or higher than 105ºC.
- Ambient temperature: ≤ 40ºC.
- Motor insulation class: Class B or Class F.
- Motor protection class: IP54 or IP55.
