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 […]
