Sodium Hypochlorite, Ferric Chloride, Sodium Hydroxide, Hydrochloric acid are some of the chemicals that are commonly used as disinfectants, coagulants, corrosion Inhibitors and neutralizing agents in a typical water treatment plant. These chemicals could be very corrosive if the right material is not selected for the liquid end of the injection pumps causing premature failures and down time, according to the company.
AquFlow has a line of pumps that was started in 1972 as Hydroflo. The range of materials available for liquid end in these pumps includes 316 Stainless Steel, PVC, PVDF, Hastelloy C, Alloy 20 and PTFE. When a pump is correctly matched to ensure chemical compatibility and accurate flow, the water treatment process becomes more dependable, the company claims.
In addition to its traditional hydraulic diaphragm metering pumps AquFlow now has a complete line of Solenoid metering pumps as well for smaller and less heavy duty applications. While the Solenoid pumps cover the lower end of flows and pressures, the AquFlow hydraulic diaphragm pumps are predominantly used for higher pressures and flow capacity as high as 3,500GPH.
AquFlow said that controlling its pumps is easy with manual stroke adjustment and optional automatic electronic capacity adjuster. In addition to the stroke it also alows to fine tune the speed for a highly accurate flow rate.
These controls are capable of taking the input 4-20mA signal from SCADA systems. Most water treatment plants are using these to control the capacities from their computers and/or the internet, the company said.
