Fireproofing Injection Pump

Injecting Alum / Accelerator into the fireproofing materials is the key to effective coverage that stays in place on structures for a very long time. AquFlow pumps are widely used for their dependability for Alum injection applications in many fireproofing systems. The ability to easily operate and adjust the flow of the pump while it is running along with the reliability of AquFlow pumps which last for years with almost no maintenance makes AquFlow a preferred pump. AquFlow also has Duplex pumps which can pump material in two parallel lines to feed two sprayers simultaneously. So whether you are spraying on cementitious material like CAFCO 300 or fire resistive plaster like Monokote you will be in control and confident with AquFlow injection pumps.

Selecting the Right Material (#4 of 8)

This is the fourth of eight articles in the series Sizing & Selecting the Right Chemical Metering Pump.

Every liquid, including water, has some corrosive interaction with pump wetted components, the degree of which depends upon the material that is coming in contact with the chemical. In our world of injecting chemicals, we come across some of the most aggressive chemicals such as Sodium Hypochlorite, Sulfuric Acid, Sodium Hydroxide etc. If careful consideration to selecting the right material is not given, the resulting failure could be expensive at best ad catastrophic and injurious at worst. There have been cases where a chemical eats through the inside of a pump housing without being noticed until it develops pin holes or explodes due to pressure, causing injuries to personnel around. Hence it is always advisable to double check the material being selected to ensure that it is corrosion resistant. The good news is is that there are corrosion resistant materials available with most manufacturers for use with such chemicals.

The first step is to know the chemical and its properties.

1. Exact composition of the chemical: Knowing that it is an acid is not enough. You need to know what acid it is and what other chemicals are in that solution.
2. Concentration: A 10% concentration of a certain chemical behaves entirely differently as compared to a 40% concentration. A material of construction which is resistant to 10% solution of something may get destroyed by 40% concentration of the same chemical.
3. Temperature: Just as the concentration these chemicals behave differently with increased temperature.

In addition to the above which pertains only to the chemical coming in contact with the internal surface of the pump, one must take into consideration events such as spillage […]

Sodium Hypochlorite – Quick Facts & Safety Information

We at AquFlow pumps know many of our customers use our pumps for Sodium Hypochlorite. We wanted to share this safety information from NJ Department of Health for their benefit.

Sodium Hypochlorite is A.K.A – Liquid Bleach, Sodium Oxychloride, Clorox, Hypochlorous Acid

Sodium Hypochlorite is a clear, slightly yellow or green liquid with a strong Chlorine odor. It is mostly diluted in water to be used as a disinfectant, household cleaner and bleaching agent.

Exposure Limits: The workplace exposure according to NIOSH and AIHA are 0.5 ppm (as chlorine) for a 15 minute period and 2 mg/cubic meter for a 15 minute period respectively.

Exposure Risks:
– It can affect you when inhaled.
– Contact can severely irritate and burn the skin and eyes with possible eye damage.
– Inhaling it can irritate the nose and throat
– Inhaling it can also irritate lungs. Higher exposures can cause build-up of fluid in the lungs (pulmonary edema), a medical emergency.
– Exposure can also cause headache, dizziness, nausea and vomiting.
– It is not combustible but is a strong oxidizer which enhances the combustion of other substances.

First Aid:
Eye Contact – Immediately flush with large amounts of water for at least 30 minutes, lifting upper and lower lids. Remove contact lenses, if worn, while flushing. Seek medical attention immediately.
Skin Contact – Quickly remove contaminated clothing. Immediately wash contaminated skin with large amounts of water. Seek medical attention.
Inhalation
– Remove the person from the exposure.
– Begin rescue breathing (using universal precautions) if breathing has stopped and CPR if heart action has stopped.
– Transfer promptly to a medical facility.
– Medical observation is recommended for 24 to 48 hours after overexposure, as pulmonary edema may be delayed.
