All chemicals  injection pumps are what are called; positive displacement pumps. Positive displacement pumps basically push the fluid into the pipe or tank where the fluid is needed. These tanks and pipes have an internal pressure. This means that the injection pump needs to be able to push the fluid at a pressure higher that the pressure inside the pipe or tank, so the fluid can be inserted in the system. Chemical injection pumps are described by the maximum pressure at which they can push the fluid. If your pipe or tank have a 100 psi internal pressure, the chemical injection pump to select has to have a higher than 100 psi maximum pressure (lets say 120 psi). This will assure that the pump can inject the chemical in the pipe or tank and also all the pressurize parts can withstand the pressure continuously without failure.

Chemical injection pumps are positive displacement pumps. These pumps have a maximum flow of chemicals they can feed. Unfortunately, because of the nature of the fluids and systems, all pumps have a discharge curve where the pumps discharge decreases when the discharge pressure increases. Normally pump manufacturers state what the flow rate is at a given discharge pressure (like 1.2 GPH @ 120 psi). It is expected that the pump will pump less at higher pressures and more at lower pressures. In this case, a pump that can pump 0.8 GPH at 120 psi, could pump 1.8 GPH at 30 psi. When selecting a pump, make sure that the specifications indicate that the pump can inject chemicals at the required rate, at a pressure higher than the required pressure for your application (the pump's flow rate can be adjusted once installed on site)

Not all chemical injection pumps are built of the same materials. the part of the pump that is in contact with the chemical, is normally built out of materials that are compatible with a large number of chemicals. What this means is, that the material will not crack or break when used with a chemicals it is compatible with. To make sure your pump is compatible with the chemical to feed, you can access a Materials Compatibility Chart to search the chemical see how it affects the most common materials used to build pumps, valves and tubes. If the pump you are thinking o using is not compatible with the chemical, just contact us and  we will find a pump for you (our email is sales@yamathosupply.com). 

There are three common modes of control: manual, digital pulse and analog input. Manual is simple control based on manually adjusting stroke length and frequency to obtain the desired flow rate. Digital pulse is a discrete contact or optical signal that can be read by the control module and converted to strokes per minute. Many chemical injection pumps have multipliers and dividers for the discrete contacts, allowing greater flexibility in the output range proportional to the pulse signal. Analog control is typically a 4-20 milliamp signal, which varies the stroke frequency in a linear fashion proportional to the output of the device, such as a flowmeter or controller. For example, a pH controller may be set to pH 7 which is equal to 4 mA and pH 9 is equal to 20 mA. The pump has 0-360 strokes per minute. A pH of 8 would be the middle of the scale equal to 12 mA and the pump would be running at 180 strokes per minute.
