INDUSTRIAL VACUUM CLEANERS FOR FOUNDRIES
In the production processes of foundries, the presence of dust accumulations constitutes a risk, which can be managed using industrial cleaning systems. Constant cleaning within the departments prevents common problems typical of foundries, such as
-
Product spillage and material waste
-
Time and costs for the maintenance of the plant
-
Health risks for operators and possibility of accidents
-
Unexpected product interruptions.
The range of Delfin DHV lobe pump vacuum cleaners has been specifically designed for heavy-duty and continuous use.
SOLUTIONS FOR HIGH TEMPERATURES
From the first phase of metal melting, we have a final casting destined to fill the crucibles, containers destined for handling to other departments. Able to withstand very high temperatures, the crucibles need thorough cleaning to eliminate residues that may compromise the next casting.
The DHV range offers solutions for working with high temperature materials and incandescent dusts that guarantee excellent cleaning by equipping its vacuum cleaners with:

-
Specific filters that withstand high temperatures
-
Special pre-separators
-
Accessories suitable for incandescent materials.
SAFE REMOVAL OF DUST FROM MOLDS
The sand molds destined for casting undergo an initial preparation phase and a breaking phase, called destaffing. During both phases, the removal of dust is essential to avoid:
-
The presence of any residues inside the prints
-
Dispersion of large quantities of dust in production environments
-
Low quality of the finished product
A vacuum system (mobile or centralized) combined with the right accessories allows the removal of any residue from the mold and the cleaning of sand under the belts and in the environments where the molds are broken.
In the case of underground tunnels, given the restricted spaces, a centralized system is required to easily recover dust leaks.

EXTRACTION FOR THE BLASTING PROCESS
When the raw part comes out of the mold after the destaffing phase, it is sanded through the blasting process. This process takes place inside dedicated booths where large quantities of small abrasive materials sand and clean the piece.
This leads to a considerable dispersion of often harmful sand in the sand blasting chambers and their removal can be a complex job.
By installing a centralised system with suction inlets near the chambers, it is possible to vacuum and reuse the abrasive material by filtering it from exhausted waste.

THE BENEFITS OF THE DHV RANGE
Continuous and regular maintenance of the system, using industrial suction solutions, prevents failures, increases the working life of the components and reduces waste. The benefits are manifold, including:
- Material recovery and raw material savings
- Reduction of costs and maintenance time
- Reduction of machine downtime
- Quality of the finished product unchanged
FEATURES AND ADVANTAGES
Delfin's DHV series industrial vacuum cleaners are the ideal solution for maintenance and cleaning in heavy industry, they make safe the removal and handling of large quantities of dusty or solid material thanks to these features
- Robust machines designed for intensive use that offer maximum power and reliability. The self-cooled pumps guarantee the achievement of very high vacuum and air flow rate values
- High filtration levels with polyester filters and Class M safety cartridges, for dust up to 1 micron. Maximum filtration efficiency thanks to an automatic alternating chamber filter cleaning system
- Easy to control, adjust and maintain, DHV vacuum cleaners are equipped with detachable and fork-liftable containers, able to guarantee maximum simplicity and safety of use. The unloading of the material takes place thanks to the activation of safety bars.
CUTTING AND FINISHING
The final treatment of the previously sanded part is carried out by using CNC machines that cut and refine it. With a large number of CNC machines large quantities of chips are created, and they:
-
make their removal and disposal difficult
-
create interruptions in the production cycles necessary for the cleaning of the machines
-
Industrial vacuum cleaners make it possible to pick up the swarf from the machinery in a continuous manner by transferring it to a collection point where it will then be unloaded onto trucks or bins.
DELFIN DEVELOPMENT AND SUPPORT
By choosing a Delfin vacuum solution you will have a dedicated team, made up of a technical office and representatives from the High Vacuum department, who will follow you during all phases of the process, from analysis to design, installation and assistance, guaranteeing maximum customization of the system.
