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.
Which pumps are commonly used for chemical dosing?
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). The specific application will dictate the best pump to use.
How do I choose a dosing pump?
First and foremost, you need to select a pump that can provide a flow rate that is adequate for your needs. Larger robust pumps are designed to be able to pump chemicals at a much higher flow rate than smaller-sized pumps.
How do I prime my chem tech 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.
How do you size a chemical feed pump?
When sizing the pump, the pump should be set 50-70% of its maximum output to maximize efficiency and not overrun pump. The 3 gpd pump would be set to inject 1-1.5 gpd; the 10 gpd would be set to inject at 3-5 gpd. In the example above, our “required feed rate” is 0.41 gpd.
How does a metering pump work?
Air operated diaphragm metering pumps use compressed air to drive a double diaphragm (two diaphragms) alternatively. A shuttle valve alternates the air flow between the two diaphragms. The flow of the media that is being pumped is adjusted by how much air pressure is supplied to the pump.
What is difference between metering pump and dosing pump?
A metering pump (also called a dosing pump) is used to add small but accurate volumes of a liquid to other fluid streams or vessels. Metering is achieved by controlling the pump’s speed or stroke length to achieve a specific delivery rate or by controlling the period of operation to supply an accurate single dose.
How do you size a chlorine dosing pump?
Multiply the Flow Rate (in gallons per minute) times the Applied Dosage in Parts Per Million Desired times 1440. Then divide by the Solution Strength being used. Household bleach is approximately 5% chlorine, pool chlorine is 10 to 12%.
How does a dosing valve work?
During active regeneration, the doser valve injects a fine mist of fuel into the exhaust stream, where it then ignites on the surface of the DOC to raise the exhaust temperature and oxidize the particulate matter in the CDPF. The Doser assembly also includes a fuel pump and filter.
