AquFlow Pumps in Cooling Tower Applications

Cooling towers are very common in industrial complexes and commercial buildings. The one thing common is that they use a lot of water. Water conservation requires that water to be recirculated. And that recirculated water needs to be treated to ensure that it does not corrode or scale the cooling elements. Additionally there are possibilities of organic growth within the water which requires treatment with biocides.

Corrosion Inhibitors – These are injected in the recirculated water to prevent corrosive damage to the components.
Scale Inhibitors – Scaling can be more damaging than corrosion sometimes as it drastically reduces the heat transfer. Anti-scalants are injected to prevent scaling in the pipes and tubes.
Biocides – There are two options here Non-Oxidizing Biocides and Oxidizing Biocides. The Non-Oxidizing biocides are dosed once or twice a week and they typically require and contact time of 4 hours. Oxidizing Biocides such as Chlorine and Bromine are used depending upon the pH of the water. Bromine is effective for pH up to 9 and Chlorine is good for lower pH around 6 or 7. Their level are usually measured using Redox (Oxidation Reduction Potential – ORP).

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.

Pumping Viscous Liquids with AquFlow Pumps

Not all liquid chemicals are the same. Liquid chemicals come in various shapes, consistencies, viscosities and solid content. In this article we are going to explore the most suitable options for pumping high viscosity liquids.

Viscosity is by itself a complex subject which requires a very detailed explanations to various kinds and measures of viscosity. For our purposes we will keep the discussion relatively simple. Viscosity of a liquid is the resistance it generates to flow. When a liquid flows it has various frictional resistances that act on it and within itself. Two major types of viscosities are the dynamic (shear) viscosity AKA absolute defined as the friction between adjacent layers of the liquid as it flows and the second one being the kinematic viscosity which is measured as the ratio of absolute viscosity to its density.

Hence the higher the viscosity is of a liquid the slower it flows or pours out of a container. If we were to take two jars of exactly the same size and shape and fill one with water and the other with honey. Then we try to pour the contents out by turning it at a 45 degree gradient downwards, we will notice that the water jar empties out in a fraction of the tie it takes for the honey to empty if it ever empties completely. This is an illustration of what viscosity does to the movement of a liquid which is the rate of flow. So now we have established that the higher viscosity liquids flow slowly.

AquFlow makes several modifications to its pumps depending upon the liquid and the application to make it ideal for these high viscosity liquids. Some of these are as follows,

1. We reduce the speed of the flow by reducing the strokes per minute. […]

Did you know Hydroflo is AquFlow?

Many of you may already know this, but we started our life as Hydroflo in 1972.

Hydroflo pumps were revolutionary in design and quickly built their reputation as one of the most durable pumps. Soon the teal colored pumps were all over known for their quality and reliability. Then after the original founder Mr. John Klembeth retired in 1996, the company changed hands a couple of times under two different managements. That is where the names Penn Process Technologies and Nikkiso come in.
In 2007, AquFlow re-launched the pump line with a new name and a fresh new look with Golden Yellow color. So whether you have a teal green pump, a yellow pump, a Hydroflo pump, a Penn Process pump, or a Nikkiso pump, you need to contact AquFlow for all the spares, accessories and replacement pumps.
