Pumps for Chlorine

CANNED MOTOR PUMP MANUFACTURER FOR CHLORINE (CL2)

Chlorine is an essential product in the chemical industry. It has contributed to the development of several daily products that have improved our health, nutrition and quality of life. Therefore it is necessary to produce, store and transport Chlorine.

Liquid chlorine is a highly dangerous substance due to its toxic, corrosive, and reactive properties.

PUMPING RESTRICTIONS FOR CHLORINE:

Liquid chlorine is highly corrosive to most materials, especially metals. It can cause rapid oxidation, leading to rust and deterioration of surfaces. Chlorine’s reactivity with moisture accelerates its corrosive effects, making it especially harmful in humid environments.

Due to its physical, chemical and toxic properties, chlorine should be handled with care. Chlorine has a high vapour pressure, which can lead to vaporization inside the pump. Vaporisation should be avoided as it can seriously damage the pump.

OPTIMEX SOLUTIONS:

By its experience in pumping chlorine, Optimex is today able to adapt the design of its machines in order to guarantee the good operation of the centrifugal pumps avoiding for example the phenomena of butter chlorine (formation of deposits if chlorine gas is combined with humidity)

Several solutions are possible depending on the suction pressure. In order to guarantee absolute safety when using liquid chlorine, OPTIMEX follows the construction recommendations of the Euro Chlor.

Examples of chlorine liquids:

Chlorine (Cl2)
Vynil Chloride

Pumps for Hydrofluoric Acid

CANNED MOTOR PUMPS MANUFACTURER FOR HYDROFLUORIC ACID (HF)

Hydrofluoric acid (HF) is an extremely dangerous and corrosive substance. Even in low concentrations, it can cause severe chemical burns that penetrate deep into tissues, affecting bones and nerves. One of the most alarming aspects of HF exposure is that the pain and damage may not be immediately apparent, which can delay treatment and increase harm. HF can also be deadly if inhaled, as it causes respiratory damage, and in severe cases, it can lead to systemic toxicity by interfering with calcium levels in the body, potentially resulting in cardiac arrest.

Despite its hazards, hydrofluoric acid has important industrial applications. It is used in glass etching, metal cleaning, and the production of fluorine-containing compounds like refrigerants and pharmaceuticals. Additionally, HF is crucial in the petrochemical industry for alkylation processes in oil refining. Due to its high risk, strict safety measures, such as specialized protective equipment and rapid medical treatment protocols, are essential when working with hydrofluoric acid.

PUMPING RESTRICTIONS FOR HYDROFLUORIC ACID:

Hydrofluoric acid (HF) is highly corrosive, posing significant challenges in handling and pumping. It aggressively reacts with most materials, causing rapid degradation and failure of equipment.

HF’s ability to penetrate deeply into materials makes it exceptionally dangerous and difficult to contain. Its corrosive action is further accelerated by the acid's ability to dissolve many materials.

The risks involved include not only damage to equipment but also the potential for hazardous leaks, which can expose workers and the environment to the acid's toxic and corrosive effects. Therefore, robust safety protocols, including leak detection systems, and special equipment, are designed for pumping HF.

OPTIMEX SOLUTIONS:

One key aspect is minimizing the number of seals and joints, as these are potential points of failure where leaks could occur. By reducing the seal lengths and optimizing the mechanical design, the risk of leaks is significantly decreased. The use of welded construction for critical components, such as the pump casing and containment shell, further enhances the integrity of the system, avoiding the need for gaskets or seals that could degrade over time.

A leak detection system could be proposed in option for monitoring the pump's integrity. This system should include sensors that can detect even the smallest leaks and trigger automatic shutdowns to prevent fluid loss and potential hazards.

The choice of materials is critical to ensure resistance to the pumped fluid and to handle the stresses of operation. For corrosive or aggressive fluids.

In summary, the design of a canned motor pump focuses on reducing potential leak points, using welded components, integrating reliable leak detection, and selecting appropriate materials to ensure safe, long-lasting operation.

Pumps for Phosgene

CANNED MOTOR PUMPS MANUFACTURER FOR PHOSGENE (COCL2)

Phosgene is a highly toxic and dangerous gas, primarily known for its use as a chemical weapon during World War I. Exposure to phosgene can cause severe respiratory damage. Inhalation may not immediately cause symptoms, but it can lead to delayed lung injury, including fluid buildup (pulmonary edema), which can be fatal if not treated promptly. Even brief exposure to high concentrations can result in death within hours.

Despite its hazardous nature, phosgene is still used in industry today. It is a key reagent in the production of plastics, pesticides, pharmaceuticals, and dyes. It is also employed in the synthesis of isocyanates and polyurethanes. Due to its toxic effects, strict containment, safety measures, and specialized equipment are necessary when handling phosgene in industrial processes to prevent accidental exposure.

PUMPING RESTRICTIONS FOR PHOSGENE :

Phosgene, though not corrosive in its gaseous state, becomes highly reactive when dissolved in water or combined with moisture, forming hydrochloric acid (HCl), which is corrosive to many materials. When handling and pumping liquid phosgene, the primary concerns are the risk of leaks, material degradation, and the formation of corrosive byproducts. Phosgene can degrade metals and other materials if exposed to moisture, which compromises the integrity of pumping systems.

The challenges in pumping liquid phosgene involve selecting materials that resist both phosgene and any corrosive byproducts. Because of phosgene’s extreme toxicity, any leak or material failure poses serious health and environmental risks, so specialized equipment, containment systems, and rigorous safety protocols are critical to prevent accidental exposure. Leak detection systems, and special design of equipment, are essential safeguards in handling phosgene safely.

OPTIMEX SOLUTIONS:

Designing and constructing a sealless canned motor pump for handling phosgene requires extreme safety measures due to the high toxicity and reactivity of the substance. A key design feature is the implementation of triple containment, ensuring multiple layers of protection. This includes an inner containment shell to house the rotor, a secondary containment system, and a third layer as an additional safeguard against leaks.

A purge system for the secondary containment is essential to manage any potential phosgene leakage. Inert gases such as nitrogen are typically used to purge the second containment area, preventing phosgene from escaping and neutralizing any reactive vapors.

The welding of critical components is vital to eliminate the need for gaskets or seals, which are potential leak points. Welded joints provide a more robust, long-term seal that can withstand high pressures and corrosive conditions, minimizing the risk of leaks.

A leak detection system must be incorporated to continuously monitor for any breach in the containment layers. Sensors should be capable of detecting even trace amounts of phosgene and triggering automatic shutdowns or alarms to ensure prompt action.

The choice of materials is also crucial. Phosgene’s reactivity requires the use of corrosion-resistant materials, which can resist both phosgene and any byproducts it might form.

In summary, a canned motor pump for phosgene must emphasize triple containment, welded construction, effective purge systems, precise leak detection, and careful material selection to ensure safe and reliable operation.
