AcuFlow Pumps & Chemical Feed Pump Systems Accessories
AcuFlow strongly suggests using a back pressure valve, pressure gauge, inlet strainer, and calibration column with chemical feed pumps to maximize life and efficiency. Your system may also require a safety relief valve and pulsation dampener depending on the application. Please ask us to quote these compatible accessories.
Back Pressure Valve (BPV)
Mounting back pressure valve on the discharge line will ensure holding a constant pressure for the discharge check assembly on the chemical feed pump. This allows for the repeatability of a constant fluid discharge per stroke and the desired accuracy.
Safety Relief Valve (SRV)
When using a motor driven pumps or Hydraulic diaphragm metering pumps capable of higher pressure than your discharge line pressure. A Safety Pressure Relief Valve must be installed to prevent over pressure from occurring in the discharge line. Installation of the Safety Relief valve must be in the line closest to the discharge of the chemical feed pump and ensure that there are no isolation valves or components capable of closing the discharge line off prior to the relief valve.
Pulsation Dampener
In some applications, pulsation is a problem, typically with most metering pumps. A Pulsation dampener helps remove a high degree of pulsing and surging in the line. They only work if installed properly, in the right order in the line, and with the right pressure bladder to offset the incoming pulsing. It is important that the directions supplied by the manufacturer regarding recommended set pressure and location of the dampener be adhered to.
Calibration Column (Cylinders)
AcuFlow offers calibration columns to calibrate chemical feed pumps and make sure that it reaches their desired flow rate. Choosing a calibration column should be based on the flow rate and the chemical compatibility to the fluid.
Pressure Gauge
Pressure gauge is a pressure indicator where you can read your discharge pressure to ensure that it is within the desired pressure range. It comes in different sizes based on customers’ applications. It comes with a gauge isolator to separate its internal components from the chemicals.
Inlet Strainer
A Strainer has a very important role in chemical feed pumps. It is mounted on the suction line to prevent any debris or impediments from reaching check valves and cause clogs. This will affect the accuracy and life of the pump.
Strainers should be replaced and checked periodically to ensure that it is in good condition and that there is no debris or any impediment that can stop the chemicals from flowing.
