To do this, follow these three steps:
- Open the priming port on top of the pump and fill it with water.
- Slowly open the suction isolation valve and the air vents on both the suction and discharge pipes.
- Wait for the pumped water to flow out of the vents, and then close both the air vents and suction isolation valve.
How do you Prime a chemical metering pump?
Chemical metering pumps need a moment to fill their solution heads with fluids and then to displace all the air out of the lines. If it is already piped to the pressured system it will be dosing into, the pump WILL NOT self-prime. You would need a valve somewhere in the line to bleed out the air; or, manually prime the line.
How do I set up a chemical feed setup?

How are chemical feed controls selected for chemical pumps?
The required chemical pumps are selected based on the strength of the chemicals and the required flow rate. When chemical feed controls are part of a process control panel, define the requirements from the control panel’s perspective. The control panel has to know the status of process variables required to control the application.

How do you remove air from a hydraulic pump?
Open the bleed valve at the top for the air to escape. Leave it open until the hydraulic fluid from the valve flows freely. This indicates all the air has been bled out. If the fluid is foamy, pass it through some gauze or alternatively, refill the system with new hydraulic fluid.
How do you get air out of hydraulic fluid?
For dissolved air, you can remove it by raising the temperature of the fluid until the air is released. This should only be done if absolutely necessary as hydraulic oil will normally tend to be at least 10% dissolved air.

How do I get the air out of my pool pump line?
The trick to bleeding the pool lines of air is to start with all the line valves closed. With the pump running, very slowly open the valves to introduce air into the pump until the pump sucks out all the air.
How long does it take to prime a pool pump?
two minutesFill The Pump With Water Allow water to run into the pump housing for at least two minutes. This will allow some water to seep into the pipes that extend from the skimmer to the pump so there'll be enough water to create suction in the pump.
What is a chemical feed pump?
A chemical feed pump, also known as a dosing pump, is a compact positive displacement pump that injects a precise amount of chemical or other substance into water, gas or steam. It is typically part of a chemical feed system that comprises a pump or multiple pumps, storage tank, pipes and control panel. There are different methods and types of pumps that can be used, but the general procedure is to draw a preset amount of the chemical into a holding container and then inject it into a pipe or tank that holds the water or other material to be dosed. Chemical dosage is dependent on the desired purpose. For example, the addition of chlorine serves many purposes in wastewater treatment, as illusted in the table below.
Why is it important to establish a pumping cycle time?
Establishment of appropriate pumping cycle times is important to protect the life of electrical motors and to prevent the development of septic conditions in wet wells, clarifiers and sumps . The cycle time can be determine by using one of the following formulas:
Can you plug values into a formula?
Even though the measurements are given in L/s, you simply plug the values into the formula, only because the units are identical. If the two flows were different you would have to do some preprocessing first. The unit L/s will cancel in the numerator and denominator and by multiplying by 100, it gives you the percent:
Do we need to do preprocessing before entering values into the formula?
We still need to do some preprocessing before we can enter all the values into the formula. For instance, the problem gives the flow in MGD, but we need it in cubic meters per day, so let's do that conversion first:
How is the motor speed of a pump controlled?
Often, motor speed (Diaphragm Stroke Frequency) for the group of pumps is controlled based on water flow rate , and the Diaphragm Stroke Length (amount of Chemical delivered per Stroke) for individual metering pumps is controlled by the chemical analyzer measuring the chemical property the metering pump is controlling.
How is a diaphragm pump controlled?
Diaphragm Pumps are more expensive. They consist of an flexible Diaphragm controlled by a motor through an adjustable stroke rod. The fluid flow rate is controlled by changing motor speed (Diaphragm Stroke Frequency) and changing the Diaphragm Stroke Length (amount of Chemical delivered per Stroke)
How does a peristaltic pump work?
Peristaltic Pumps are simple, but can be expensive. They consist of a continuous tube wrapped around a rotating squeegee that pushes fluid through the tube. A motor controls the rotating squeegee. The fluid flow rate is controlled by changing the motor speed.
What is a solenoid pump?
Solenoid Pumps are the simplest and least expensive type of Metering Pump. They consist of a spring return piston controlled by an electric solenoid. Each time the pump is stroked (solenoid On – Off) a fixed amount fluid is pushed out by the piston. The fluid flow rate is controlled by increasing the stroke frequency.
How are chemicals added to a process?
In a process control application, chemicals are usually added in liquid form at a controlled rate using positive displacement metering pumps. The required chemical pumps are selected based on the strength of the chemicals and the required flow rate.
Can you buy a chemical feed system?

How to contact Madden metering pump?
You can call (800) 369-6233.
What keeps a chemical meter pump from displacing liquid?
Air keeps the chemical metering pump’s wetted end from displacing liquid. Until liquid is forced inside, or the air is bled out of the system, the pump will sit there and stroke forever when air locked.
What happens when a chemical metering pump is wetted?
If the chemical metering pump’s wetted end has air in it, the stroke of the diaphragm will not move air forcefully enough to unseat and firmly reseat these check ball valves; which results in the liquid in the piping remaining stagnant. Air keeps the chemical metering pump’s wetted end from displacing liquid.
How does a positive displacement diaphragm pump work?
Positive displacement, diaphragm metering pumps work using a check ball valve at the suction end and discharge end of the pump. These allow for a fixed amount of liquid to enter the pumps solution head with each backward stroke of the pump, and for that same fixed amount to then exit the pump with the forward stroke.
What does it mean when a chemical metering pump is air locked?
What it means when a chemical metering pump is air locked. Air is not the friend of a chemical metering pump. Air is hard to compress, and as a result, very hard to move. Diaphragm type metering pumps do not move air well, if at all, unlike water which is much denser than air. So if your chemical injection system has air in ...
Is a Madden pump self priming?
Madden chemical metering pumps are self-priming; but to a point. Chemical metering pumps need a moment to fill their solution heads with fluids and then to displace all the air out of the lines. If it is already piped to the pressured system it will be dosing into, the pump WILL NOT self-prime.
Do metering pumps move air?
Diaphragm type metering pumps do not move air well, if at all, unlike water which is much denser than air. So if your chemical injection system has air in the suction or discharge piping, do not be surprised when your application experiences. diminished flow rates or even no flow rate at all from the chemical injection pump.
