Metal Forging Industry

TDS-DYI SHENG’s pneumatic double diaphragm pump has passed the EU CE certification and ATEX explosion-proof certification, which is very suitable for the transportation of high-risk flammable liquids. In addition, the diaphragm siphon design has excellent wear resistance and durability for fluids mixed with slurry. Even if the particles are mixed in the liquid, as long as the larger particles are filtered through the initial stage and the particle size is maintained within the allowable particle range, it can be transported smoothly without clogging. At present, pneumatic diaphragm pumps have been widely used in various metal forging /CNC processing industries.

Application: Methanol, Parting agent, Waste effluent recycle, Red Lead Primer, Rust Shield Enamel

Advantages and Applications:

High safety, motorless operation, ensuring safe use in hazardous industrial environments.
Heat and chemical resistance, suitable for handling cooling liquids and chemicals in casting processes.
Able to transport particle-laden and viscous fluids.

Why Are Air-Operated Diaphragm Pumps Suitable for Transporting fluids of Release Agent?

Excellent Chemical Resistance Materials
The wetted parts of pneumatic diaphragm pumps are primarily made of metal and plastic materials. By utilizing the different characteristics of these materials, they can cover the transportation of up to 99% of chemical substances. You can refer to the "Material Chemical Resistance Reference" to understand the applicable material specifications for conveying fluids.
Air Pressure Driven
Air powered diaphragm pumps do not use electric power, eliminating concerns about pump overheating due to overload or generating sparks during operation, which could pose an explosion risk.
Excellent Shear Force
Dual diaphragm pumps exert very low shear force on the transported fluid, preventing the destruction or reaction of molecules. This is crucial for the safe conveyance of substances.
Full Bolted Structure
The design with full bolts ensures secure locking for complete sealing and pressure resistance. This prevents leakage, ensuring the safe conveyance of substances without impacting environmental safety.
Leak-Proof Sealing Structure
For DYI SHENG TDS pneumatic diaphragm pumps, complete sealing performance is required at each joint to effectively prevent liquid leakage, reducing environmental pollution. The diaphragm design prevents the direct leakage of transported liquids to the external or internal parts of the pump, ensuring the safety of the environment and operators.
Ability to Run Dry
Pneumatic double diaphragm pumps allow for prolonged dry running without causing pump damage or overheating.
No Heat Generation
During the operation of AODD pumps, they do not generate high temperatures or emit harmful gases, allowing for the effective and safe conveyance of chemical substances.

Why are Air Operated Double Diaphragm Pumps Suitable for Metal Casting Industry Applications?

Leak-Free Operation

The dual-diaphragm structure of the pump ensures that metal liquids do not leak during operation, enhancing safety and preventing fluid contamination.

Self-Priming Capability

These pumps exhibit excellent self-priming performance, effectively suctioning molten metal liquids and transporting them to casting molds or other required locations.

Controllable Flow

The pump's flow and pressure can be adjusted to ensure different fluid requirements during various stages of the casting process, providing a more flexible operation.

SUITABLE FOR

In the metal casting industry, AODD pumps are primarily applied in the following areas:

Circulation of Coolant

During the metal casting process, air-operated double diaphragm pumps are used to deliver coolant to cooling systems, helping to control metal temperatures and ensure casting quality.

Casting Mold Slurry Treatment

These pumps are ideal for transporting casting mold slurry. The diaphragm design ensures minimal wear on parts, and the air-driven mechanism enhances safety when handling flammable liquids.

Chemical Process Fluid Transfer

Air-operated double diaphragm pumps are used to transfer acidic or corrosive chemical liquids, such as release agents or cleaning solutions, during the casting process.

Lubricant Transfer

In metal casting, the circulation of lubricants is critical. Air-operated double diaphragm pumps ensure a stable and reliable supply of lubricants to maintain the proper operation of production equipment.

Spraying Coatings and Protective Agents

For surface treatment of castings, special coatings or protective agents are often applied. Air-operated double diaphragm pumps provide precise flow control for spraying or supplying these coatings.
