How Does a Sewage Pump Work?

What is a Sewage Pump?

A sewage pump is used to transfer sewage liquids and solids from one place to another. Usually, in residential applications, sewage includes soft solids up to 2" in diameter is pumped from a sewage basin to a sewer system or a septic tank. A sewage pump is installed at the lowest point of the sewage basin.

Since the pump is submerged most of the time, it is also referred to as a submersible sewage pump. Sewage pump can be automatic, manual or dual mode. A dual mode pump contains a piggyback plug, which allows the pump to be used as either manual, wherein the pump bypasses the switch and is plugged in directly into the socket or as automatic, wherein the pump is plugged in through the floating switch and works only when the switch is activated.

Due to a possibility of sewage overflow, it is generally not advised to use a manual sewage pump inside of a sewage basin.

Sewage pumps are centrifugal pumps, with the special design enabling solids to pass without clogging the pump. When the pump is turned on, the motor starts to rotate the impeller, creating the pressure that pushes water into the impeller and goes into the discharge pipe.

The sewage pump is powered through a 10-25 ft. electric cord. Depending on the model, the voltage can be 115, 230, 460, or 575 volts. The pump housing, which contains a motor and an impeller, is made with cast iron and is built for long-term use.

Types of Sewage Pumps

Effluent Pumps - effluent pumps are the pumps most often uses in the small on-site system. They are designed to pump effluent, the effluent flowing out of a septic tank. This effluent is relatively clear liquid because the solids have developed out in the septic tank. The effluent pump can pump higher levels and more efficient than the other types of sewage pumps because these pumps don't have to handle sewage solids.

Solid Handling Pumps - these pumps are also called sewage ejector pumps made to pump raw sewage. Raw sewage contains too many solids for most pumps, so only solids-handling pumps should be used where raw sewage has to be pumped.

Grinder Pumps - a grinder pump is much like a solid-handling pump. It can pump raw sewage. The difference is that the grinder pump has rotating blades, like garbage grinders that cut and grind the solids into small particles before the sewage is pumped.

Benefits of Sewage Pumps

Sewage pump is designed to remove water build-up from basements and crawlspaces and safely deposit it through the wastewater system of a house. The operation of a sump pump is relatively simple, although their installation is more complicated.

Here the major benefits of having a sewage pump:

• Prevent flooding damage - When heavy rains trigger a flood of water into your basement, you can quickly have 15 inches of flood water covering the floor and damaging almost everything inside, which can be especially devastating if you store valuable items in the basement. With a working sump pump, this disaster can be averted easily.

• Reduce the threat of mold and mildew - Continual dampness inside a basement from water in stagnant pools will contribute to the growth of mold and mildew. Not only are these both damaging to building material, but they are health problems as well.

• Reduce the risk of fire - The water will short-circuit the appliances in the basement, such as laundry machines, water heaters, and heating systems. So, aside from ruining these valuable appliances, water can also create a fire danger. A sump pump will keep the water from threatening equipment that could trigger household fires.

Maintenance and repairs of this device

• If a ground fault circuit interrupter is installed at the outlet or in the electric panel, make sure it is working. Use the test button on the unit to confirm proper ground-fault protection.

• Remove the cover. There are 3 common types of lids, each with slightly different removal methods.

• Inspect the pit for a silt or debris that might obstruct the float or clog the pump impeller or discharge tube.

• Make sure that it is positioned so that the float that turns it on and of moves freely and is not obstructed by the walls of the sump, discharge piping or other objects.

• Check the drain line from the pump until it meets the air gap for any signs of corrosion, holes, damages or leaks.

• Check for a small 3/16 to 3/8 inch deep hole in the discharge pipe directly above it.

• Visually inspect all alarm mechanisms (if applicable), exposed metal parts and connections for corrosion. You may apply a silicone water repellant spray to deter corrosion. Refer to manufacturer usage instructions to apply silicone spray.

• Verify that there is a check valve in place on the drain line just above the pump cover. Contact a licensed plumber to add a check valve if one is not present.

• Check to make sure the air gap in between the interior and exterior discharge pipes should be open and clear of debris.

Conclusion

There are many pumping station facilities, including pumps and equipment for pumping fluids from one place to another. They are used for a variety of infrastructure systems, such as supplying water to canals, and the removal of sewage to the processing site. This station in the sewage collection system also called the lift station, are designed to handle raw sewage that is fed from underground pipelines.

Businesses can benefit from using sewage pumps as it can handle loads of water in a small amount of time. It is cost efficient if you have a sewage pump to handle those unwanted water and wet waste.

Chemical Process Pumps – Designed to Withstand Corrosive or Aggressive Liquids

For many years, the chemical industries have played a crucial role in the world economy. The chemical industries are the main factors to convert raw materials into desired products that we use in our daily lives.

In every chemical industry, there is a growing problem to transfer the chemical from one place to another. Many chemicals are so dangerous and harmful to the human body. Therefore, the difficulties of transferring these oils are the headache of all the owners of the chemical industry.

Basically, chemical pumps are used to transfer liquids from one container to another container. And they are designed to withstand corrosive or aggressive liquids such as paint, fuel, bleach, etc. It is widely used to move liquid chemicals at high pressures.

Hazardous chemicals are chemical products that are eliminated in the workplace and with the possibility of causing damage. Hazardous chemicals are harmful to workers in the industry who do not know about them or know their health effects. Day by day, there are many industries such as textiles, oil and petroleum, pesticides and pharmaceuticals, mining, motor vehicles and many more that produce hazardous waste.

The importance of chemical process pumps in the handling of dangerous chemicals

Chemical process pumps are specially designed to assist in manufacturing and other processes that include hazardous waste and other chemical products. It is used mainly used in manufacturing industries where there are dangerous chemicals. Chemical process pumps are made for hazardous chemicals and corrosive acids that will ensure that machines and workers are not damaged or affected during contact with each other. This situation occurs mainly in the chemical, pharmaceutical, and other processing industries.

Chemical process pumps can prevent chemicals easily in meeting with the skin and any exposure that may cause allergies and uncomfortable work environments. Handles gases and chemicals at high temperatures can be used in industries such as the battery manufacturing industries.

Chemical process pumps easily prevent reactions between hazardous chemicals and other chemicals. These pumps are made with the suction capacity to protect the material and go to the required locations. Some hazardous chemicals react with common metals and can be avoided by having special finishes on internal surfaces. Some chemicals and gases such as acetic acids, naphtha, benzene, and toluene are classified as dangerous because they are highly flammable. Handles poisonous gases and prevents them from mixing with normal air.

How do Dosing Pumps Work? An Overview

Powered by electric motors or air actuators, dosing pumps are these small displacement pumps – primarily employed for pumping a limited flow of chemical substances into steam, water or gas flow. There are several methods that can be employed to drive these pumps. However, they primarily function by drawing a limited amount of water into a chamber, followed by the “injection” of this volume of chemical into the pipe or a tank which is actually being dosed. These pumps are used in several industries including:

• Agriculture
• Manufacturing Industry
• Medicine
• Food processing 
• Mining

In short, these pumps are widely used as essential automation components to deal with large amounts of fluids. Notably, when it comes to waste water treatment, dosing pumps are used to inject products such as chlorine into fluid streams or water in order to cause a chemical reaction. The particular reaction is meant to maintain the desired level of pH or to destroy pathogens. 

How Do Dosing Pumps Work?

As has already been indicated above, there might as well be several methods employed to run dosing pumps depending on the brand or the model but the primary function of these pumps is to inject a measured amount of chemical into a pipe or a vessel. 

Different Models and Different Ways in which they Function

There are 4 different types of models made available today. Each of these units differs in terms of action and the mechanisms backing them. Accordingly, they are suited for myriad applications, chemicals, and pressures. 

Topping the list is the Diaphragm Type Pulse Injection – a model controlled by a solenoid coil. The coil is meant to suck in and inject the chemical in pulses and it’s the time gap between the pulses that actually controls the rate of flow. This particular type of technology is actually ruled out by modern technicians as outdated and less effective since the product is delivered in pulses. They are notably simple as far as their operations are concerned. Additionally, they are cheaper than most of the other models. 

The Diaphragm type constant injection is a more accurate version of the aforementioned model – since it is filled and emptied by a piston – delivering a steady flow rate. The rate at which the product is injected out of the pump depends on the amount of product being dosed. With just the right kind of control, you will be able to achieve various dosing rates with this machinery. 

Then there are the Lobe type pumps that inject a certain volume through an arrangement of impellors that resemble a gear. Once again they are not really known for the accuracy of their function owing to their wearing surface. It is wiser to invest in them only when you’re working with products backed by self-lubricating capacity so that chances of wearing down are reduced.
