7 Big Advantages of HCS Centrifugal Pumps:

EN733 Standard Monoblock Centrifugal Pumps HCS series with following advantages:

1. Inlet/outlet DN comply with requirements of Standard EN 733 standard pumps (DIN 24255) and UNI 7467
2. Flanges in compliance with UNI 2236 and DIN 2532
3. Single-impeller centrifugal pump featuring axial intake and radial discharge.
4. High efficient and energy saving
5. Wide operation range
6. Compact structure
7. Wide application range

HCS Monoblock Centrifugal Pumps Technical Data:

• DN: 32-80mm
• Flow rate: upto 250 m3/h
• Head : up to 100m
• Media Temp: -20℃ to +120℃
• System Pressure: Max. 12 bar (PN12)
• Max. operating pressure: 12 bar
• Ambient temperatures: upto +40℃
• Liquid temperatures: upto +85℃

Features of Back Pull-out Facility

All our HCS centrifugal pumps incorporate the “back pull out” facility allowing the remove of the complete rotating element without disturbing the pipework. This features enables quick and simple maintenance to take place.

Interchangeability

Many of the components are interchangeable, this features resulting in a reduction in spares requirements, and an initial cost saving.

EN733 Standard Excellent Bearing Housing Design

All our EN733 standard centrifugal pumps, incorporated with lifting eye, to simplify removal of the rotating element during maintenance, “safe guards” are installed to prevent rotating shaft from human reach while in operation.

Main materials

• Volute casing: Cast iron
• Pump Cover: Cast Iron
• Shaft: Carbon Steel or stainless steel
• Impeller: Cast iron or Bronze or Stainless steel
• Shaft seal: Gland packing seal or Mechanical Seal

 

Main 7 Applications of HCS Centrifugal Pumps

HCS standard monoblock pumps are qualified to handle clean water or liquids similar to water in physical and chemical properties.

The PH value of the transmission liquids shall be between 6.5 and 8.5.

HCS pumps widely used for farm irrigation and drainage in factories, mines, schools, hospitals, hotels and cities.

it also can be used as pumps for fire fighting system and spraying system with impeller of welding stainless steel or casting copper:

1. Regional heating,
2. community heating,
3. central air conditioning,
4. cooling system,
5. industry water supply,
6. washing system,
7. boosting system.

Note for inlet pipe installation

1. Do not use soft rubber tube for inlet pipeline during centrifugal pump installation.
2. The foot valve shall be vertically installed with a distance of at least 30 cm from the water bottom to avoid suction of sediment (A).
3. All connections of the inlet pipeline must be sealed.
4. To ensure water suction, it’s necessary to reduce the quantity of bents of the pipelines.
5. The diameter of inlet pipeline must not be less than that of the pump outlet to avoid big hydraulic loss and small water flow.
6. Pay attention to the water level during operation.
7. The foot valve shall not be above the water surface (B).
8. In case the inlet pipeline is more than 10 m in length or over 4 m in hoisting height, the diameter of the inlet pipeline must be greater than that of the pump outlet.
9. The pipelines should be anchored so that no stresses whatsoever is transmitted to the pump.
10. It is recommended to install a filter on inlet pipeline to avoid incoming of solid particles to the electric pump.

Note for outlet pipe installation of centrifugal pumps:

The diameter of the outlet pipeline shall be not less than th outlet.
