What is Chem Tech pulsafeeder?
The Chem-Tech Series 100 is the standard by which all other dosing pumps are judged, Chem-Tech Series 100/150 pumps with motorized-diaphragm technology deliver dependable performance and extended longevity. The Series 100/150 provides quiet, consistent metering over long periods of time in a compact form.
How do you prime a pulsafeeder pump?
While pump is running, turn adjustment knob counterclockwise. Run with valve open until a solid stream of fluid comes out of the bypass tubing with no air bubbles. Close air bleed valve by turning adjustment screw clockwise. Chemical should reach the pump head after a few minutes of operation.
What type of pump is used for chemical feed?
Types of Chemical Feed Pumps Chemical dosing pumps that are used for water treatment fall into the following categories: centrifugal pumps, piston pumps, and displacement style pumps (peristaltic and diaphragm pumps).
How do I choose a dosing pump capacity?
With that in mind, a metering pump should be sized so that the maximum expected flow rate is 85% to 90% of the pump’s capacity, which will leave room for additional capacity, if needed. The minimum capacity should never be less than 10% of the pump capacity to maintain accuracy.
How does a chemical feed pump work?
A dosing pump draws a measured amount of liquid into its chamber and injects the chemical into a tank or pipe that contains the fluid that is being dosed. It’s powered by an electric motor or an air actuator and has a controller that turns the pump on and off and manages the flow rate.
What is the difference between 50 GPD and 100 GPD?
Normally, the lower the GPD volume, the higher the removal rate is. The 50 GPD membrane has a 97% rejection rate whereas FilmTec redesigned their 75 GPD membranes and it now has a 99% rejection rate. Along with redesigning the 75 GPD, they redesigned the 100 GPD to where it now has a 98% rejection rate.
What is the difference between 50 GPD and 100 GPD membrane?
The rejection rate of a 100 gph membrane is lower than a 50 gph membrane. 100gph will produce more clean water output with slightly higher Tds but at the same time the waste water output is less.
How do you calibrate a chemical feed pump?
Calibration Procedure
- Calculate the capacity of the pump at the speed and stroke rate at which the test will be run.
- Fill the calibration cylinder with the product that the pump is feeding.
- Record the starting level of the calibration cylinder.
- Run the pump for the desired amount of time, generally 0.5 – 1.0 minute.
