What is the function of a metering pump?
A metering pump is used to add small but accurate volumes of a liquid to other fluid streams or vessels. Metering pumps are also called dosing pumps and proportioning pumps. A metering pump must be able to deliver liquid with an accuracy of greater than 3% across a wide range of discharge pressures.
What type of pumps are metering pumps?
A metering pump is a form of reciprocating pump that uses positive displacement to release a precise amount of a liquid with each of its strokes. The rotary motion of the pump is converted into reciprocating motion through the use of a wheel and worm shaft.
Where are metering pumps used?
They are commonly found to pump chemicals in water treatment applications, such as water for drinking, swimming pool or treatment in wastewater. Food processing plants also use metering pumps to blend liquid ingredients or in laboratory and medical applications where accuracy is required.
What is fuel metering pump?
A metering pump moves a precise volume of liquid in a specified time period providing an accurate volumetric flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering.
What are chemical metering pumps?
Chemical metering pumps dispense liquids at precise rates. Also known as dosing pumps, they can handle harsh and hazardous fluids such as bases, slurries, and corrosives. Chemical metering pumps dispense liquids at precise rates.
What is a fuel metering pump?
What is metering in diesel engine?
The term proper metering is applied to diesel engine injection system in which delivering the same quantity of fuel to each cylinder for each power stroke depending upon the engine load.
What is fuel metering valve?
Fuel metering valves are the gas turbine’s throttle control. Industrial gas turbines generate power from the expansion of hot gases when fuel is burnt in the compressed air. The proportions of the fuel and air mixture decide how much power the gas turbine delivers.
What is pump stroke?
The number of strokes the polished rod completes in one minute. This determines the rate at which liquid is pumped. If the number of strokes per minute is increased, the pump rate is also increased. This term is also referred to as stroke speed. Privacy.
How does a solenoid metering pump work?
How they work. A solenoid moves the solenoid shaft forwards and backwards by switching on and off. This stroke movement is transferred to the diaphragm in the dosing head. Two check valves prevent the feed chemical from flowing back during pumping.
How do you prime a pulsafeeder?
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 enclosure holds a chemical metering pump?
This cost-effective enclosure holds a single chemical metering pump and is constructed of UV stabilized and chemical-resistant linear polyethylene for longevity in harsh chemical and weather environments. Looking for our PCS-PLUS Pump Containment Enclosure, click the link and we will gladly take you to that section.
How does a metering pump work?
How do metering pumps work? Most metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the dosing line on the compression stroke. The pump settings can be changed to achieve consistently accurate metering.
What types of metering pumps are in the database?
The database contains all solenoid metering pumps, motor-driven metering pumps, process metering pumps and peristaltic pumps from ProMinent. They are divided into more than 30 different product ranges. Narrow down your search by clicking on different selection criteria. Do you have a specific industry, operating mode, medium or viscosity in mind?
How can the pump settings be changed to achieve consistently accurate metering?
The pump settings can be changed to achieve consistently accurate metering. The accurate control of the pumps is made possible by microprocessor technology. Sophisticated monitoring functions ensure operational reliability and guarantee minimal chemical consumption yet optimum disinfection.
