A Simple Solution for Degassing Problems

AquFlow Series 1000

Some chemicals are susceptible to giving off gas while being moved or pumped. This challenge is especially complicated when this gas could get trapped in a small volume pump. Then the pump would not move any liquid as the gas trapped in the pump chamber would expand and contract with each stroke without moving any liquid. Fortunately, this is an issue AquFlow can easily overcome.

We have a special degassing diaphragm head which senses and expels the gas through a valve at the top where the gas usually tends to rise. This special design of the degassing head is very popular among municipal water and wastewater treatment facilities that use 12% sodium hypochlorite. With our assistance in proper pipe layout and a degassing head the possibility of degassing is minimized.

AquFlow over the last 42 years have come up with many such specialized industry solutions such as IVAX (Intelligent Verification and Control System), tubular pump for viscous liquids, etc. Please visit our website to learn about various configurations and newest product developments at www.aquflow.com

Skid-Mounted Systems Built Specifically for You

AquFlow offers customized ChemInjector systems based on your specified applications. We provide everything you need for an accurate chemical injector system. Most assemblies are skid-mounted, which is then placed at the site. Some chemical injector systems are too large for skid mounting. For very large systems, AquFlow provides on-site assembly as well as the option for mobile chemical injector stations.

Features:
* Systems are customized for you based on your chemical dispensing requirements.
* A complete turnkey system that can perform dependably and durably with minimal down time.
* Every component that goes into the system is pre-matched and tested so there are no incompatibility issues.
* On-site assembly available for systems that are too big for skid mounting.
* Mobile systems mounted on carts / trailers or other vehicles for covering long distances.

For more information on our standard ChemInjector packages and other available skid systems, contact our sales team at sales@aquflow.com.

Four Differentiating Facts – Solenoid Vs Hydraulic Diaphragm Metering Pumps

Hydraulic Diaphragm Series 900

Solenoid Series 200

1. Cost of Ownership: While it is true that solenoid pumps are often less than half the purchase price of hydraulic diaphragm metering pumps, the total cost of ownership tells a completely different story. Hydraulic diaphragm metering pumps last over 10-15 years in the field with almost no maintenance. Solenoid pumps usually need service and replacement diaphragms every 6-9 months depending upon usage. Typically, a solenoid pump is considered good if it lasts 2-3 years in the field.

2. Balanced Diaphragm Vs Imbalanced Diaphragm: Hydraulic diaphragm pumps have process liquid on one side and hydraulic liquid on the other side to achieve balanced pressure on the diaphragm. This results in the diaphragm experiencing almost no mechanical stress which ensures a long life. On a solenoid metering pump, you have all the process pressure on one side with nothing to balance against it on the other side. This puts a lot of mechanical stress on the diaphragm and eventually causes bulging and failure.

3. Accuracy Matters: Due to the very nature of its design, hydraulic diaphragm pumps are extremely accurate throughout its life. That is the reason they are the only pumps that can meet API-675 standards. Solenoid pumps cannot because the diaphragm could bulge out or balloon even before it fails, which causes the accuracy to drop significantly.

4. High Performance: Solenoid pumps are good for low flow and low pressure applications usually under 100 psi. The duty cycle also needs to be very light. On the other hand, hydraulic diaphragm pumps can achieve flows and pressures hundreds of times higher than solenoid pumps. Hydraulic diaphragm pumps are also made for heavy duty or continuous operations 24/7.

So while solenoid pumps have their place […]

How Does a Teal Pump Change to Yellow?

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.

Why Matching Accessories is All The Rage in the Pump World

You seldom use a metering pump by itself. You need many if not all of these accessories based upon your application:

Back Pressure Valve
Safety Relief Valve
Calibration Column 
Inlet Strainer
Pressure Gauge 
Pulsation Dampeners 
Injection Quills, etc.

Shopping around for these accessories could be time consuming and complex when you are trying to match the material of the wetted parts, connection sizes and pressure capabilities. Then when you finally have it all put together and something is not working as expected, the blame game begins. It’s the pump’s fault, no it is the valves’ fault, or may be the pressure gauge or calibration column is not accurate. Call all these vendors who conveniently blame every other component except theirs.

To solve this common problem AquFlow provides a complete set of matching accessories. Just ask for these accessories when you order the pump. So it all comes together and ready to use. In the unlikely event something does not work, you only need to call one company – AquFlow. Please call us and ask us to email you the brochure for these accessories.
