Expedited Production with 2-3 Day Delivery Coast to Coast from AquFlow

AquFlow over the years has built a solid reputation for industry leading quick production and deliveries. We have now formalized the process of an Expedited production, testing and deliveries for those unplanned pump emergencies. For most standard pump models we can expedite the whole process from order to delivery in less than a week. Call us and ask for Expedited Pump Delivery (EPD) if you need a pump in a hurry.

We have partnered with a couple of major LTL trucking companies that can deliver any pump, skid or a complete system to any of our customers coast to coast in 2-3 days. This is the standard service without paying any Express or Expedited charges. So when you need a large pump, skid or a complete system to be delivered almost anywhere in the 48 states, please ask us for the 2-3 days LTL service without any extra charge. This is just another way we try to serve our customer better and faster.

Major Factors to Consider in Designing and Installing a Chemical Injection Skid System

4. Control Systems For The Skid

This is where we decide about the controls for the delivery of the chemical (and hence the pump) and sensors to verify if the system is doing what it is expected to do.

The first thing we take into consideration here is the power that is available. That will determine the selection of the motor, sensor and controls. Usually that power is single or three phase AC voltage. Although in remote areas there could be the need for DC power especially if the source is a generator or solar.

The flow of the chemical can be regulated by using a VFD on the motor to regulate the speed or by an automatic stroke adjustment system (like AquFlow’s ECCA) which will increase or decrease the effective stroke length. Many engineers prefer a combination of the two controls calling it a Dual Axis control. Both these controls can be driven by a 4-20 mA signal from an external system such as SCADA which takes into consideration several other inputs such as flow or quantity of the water to be treated, contamination level etc.

Once the flow of the chemical is controlled it is often recommended to measure the output of the chemical in the pipe line by suing a flow measurement device. This device again communicates back to a central system like SCADA which takes this input and fine tunes the pump flow capacity by one or both of the above methods.

If an external control system like SCADA is not available, AquFlow offers a self contained control unit called IVAX which stands for Intelligent Verification and Control System. This has the ability to offer a complete feedback loop to send control signal, verify the actual […]
