Key Features of Submersible Wastewater Pumps

High Durability and Efficiency

A submersible pump is designed for high durability and efficiency, making it ideal for demanding applications. These pumps are constructed with robust materials such as cast iron, stainless steel, and high-chrome alloys, ensuring longevity, corrosion resistance, and wear resistance. This durability is crucial for maintaining reliable operation in harsh environments where the pump is exposed to abrasive and corrosive substances.

Efficiency is another standout feature of submersible waste water pumps. Their design allows them to operate while fully submerged, enhancing cooling and reducing the risk of overheating. This results in longer motor life and less downtime for maintenance. Additionally, the direct contact with the fluid minimizes energy losses associated with suction lift, making submersible sump pumps more energy-efficient than other pumps.

Advantages of Submersible Designs in Harsh Environments

Submersible designs offer significant advantages in harsh environments. One of the main benefits is the ability to handle solids and debris without clogging. Solids handling pumps, an industrial submersible pump, are specifically engineered to manage fluids with high solid content, making them ideal for waste water applications involving sludge, effluent, sewage, and other particulate-laden liquids.

The submersible design protects the pump's components in harsh environments. Being fully submerged in the fluid helps to dissipate heat generated by the motor, preventing overheating and ensuring continuous operation. This is particularly beneficial in industrial settings where pumps must run for extended periods under demanding conditions.

Moreover, submersible sewage pumps are less prone to issues like air locking and cavitation, which are common problems in non-submersible ones. The submerged operation also means that these pumps operate more quietly, reducing noise pollution and making them suitable for residential, urban, and industrial sites.

Submersible Sewage Pump: Core Components and Their Functions

A submersible sewage pump is a marvel of engineering, made up of several key components that each play a crucial role in its operation. Here, we break down these core components and their functions.

1. Motor: The motor is the heart of the pump. It is typically a robust, electrically powered component that is hermetically sealed to prevent water ingress, which could cause a short circuit. The motor provides the power needed to drive the impeller and pump the sewage.

2. Impeller: The impeller is a rotating component driven by the motor. It has vanes that draw in the sewage and propel it outwards by centrifugal force, pushing it through the pump and into the discharge pipe.

3. Pump Casing (Housing): This is the shell that houses the impeller and motor. It is typically made of durable materials like cast iron or stainless steel to withstand the harsh conditions inside the sewage tank. The casing also has channels that guide the sewage from the impeller to the discharge pipe.

4. Seal Chamber and Seals: This component prevents sewage from entering the motor compartment. Mechanical seals are used, which create a watertight seal between the motor and the pump casing.

5. Discharge Pipe: This is the pipe through which the sewage leaves the pump. It's designed to handle the pressure of the sewage being forced through it by the pump.

6. Power Cord: This is what connects the pump to the electrical power source. It's designed to be waterproof and durable to ensure reliable operation of the pump.

These components work together to provide a robust and efficient system for managing and transporting sewage.

How To Pick The Perfect Submersible Sump Pump?

Submersible sump pumps are the preferred choice for most residential applications, but not all pumps are made equal!

Submersible pumps come in multiple horsepower ratings and have different accessory options, and it can be confusing to choose between them.

This guide will explain everything you need to know to confidently choose the right submersible pump for your sump pit and ensure it's the right size for the job. After all, a properly sized sump pump saves money and hassle in the long run.

How to Properly Size a Submersible Sump Pump
There are four major factors to consider to be confident you're choosing the right submersible pump for the job. There's a saying about "bigger is better," but with sump pumps, this is not true.

Oversizing a sump pump can lead to constant cycling and premature burnout of your pump system. Under-sizing a pump can lead to the same issue, so it's important to choose a submersible pump that most closely fits the needs of your sump pit.

To properly size a submersible sump pump and safely put together a proper sump pump system, you'll need to:
Choose the right horsepower
Choose the right float switch
Choose the right water alarm
Choose a backup sump pump system

How to Choose the Right Horsepower (HP) for Sump Pumps
Horsepower is the most important factor when determining which sump pump is best for your application, and it's used to determine how much power your pump can produce to empty your sump pit through the discharge piping.

It's important to understand that each submersible sump pump has its own pump curve and recommended uses, so make sure to check the specifications of the pump to make sure it's going to work for you since total pump output can vary between manufacturers. This information can be found for each pump on our product pages.

If you're replacing a previous pump, typically you should stick to the same horsepower (HP) rating as your old pump unless you experienced any issues with that pump before it failed. Every sump pump has a data plate that can be checked to determine all the most important pump information, including HP ratings and model number for reference.

If you can't locate the information or can't find your user manual, we have a manual lookup tool you can use to find your old pump's manual.

1/3 HP Submersible Sump Pumps
For most average-sized homes in areas with average water tables, a 1/3 HP sump pump should be sufficient. Typically, 1/3 HP pumps can handle 7' - 10' vertical lifts from the sump pit if they have one 90-degree elbow and a horizontal pipe run between 3 feet and 25 feet.

1/2 HP Submersible Sump Pumps
If you live in an average-sized home with an above-average water table, you will most likely need a 1/2 HP sump pump. These pumps will generally pump about 35%-40% more than their 1/3 HP counterparts, and can also handle higher vertical lifts for water being pumped through your discharge pipe.

When you have a slightly higher vertical lift (10-15 feet) or a long horizontal run (example: 30-150 feet), you may notice a loss of water flow due to the increased friction from the longer runs. For those conditions, you may need a higher pumping capacity (HP and GPH) to overcome that loss.

3/4 HP - 1 HP Submersible Sump Pumps
3/4 HP Submersible Sump PumpFor people living in high water table areas, flood plains, low-lying areas susceptible to flooding, or have a deeper basement, you will likely need a stronger 3/4 HP sump pump

These pumps will generally provide a 20% - 25% increase in pumping capacity over a 1/2HP sump pump. In addition, if you have an installation where you need a high vertical lift or head (20-30 feet) and/or a long horizontal run (150-250 feet), 3/4 - 1 HP pumps provide the additional power needed to pump that water. These higher-output sump pumps are also ideal for outdoor pump applications.

When dealing with higher GPM and longer pumping distances, special attention needs to be placed on choosing a proper discharge pipe diameter to prevent problems with higher-powered pumps.

Wifi Submersible Sump Pumps and Accessories
Float switches, water alarms, and backup pumps are all necessary to prevent your basement from flooding, which is why you need a sump pump in the first place.

Most sump pumps will come with a float switch, or you can purchase a replacement separately. We recommend electronic float switches because they take up less space in your sump pit and are the most reliable switches on the market.

With water alarm systems, wifi-enabled kits can be purchased that connect to your sump pump and call, text, or email you if anything is going wrong with your sump pit. They are extremely useful to have because a regular beeping water alarm won't do much good if no one is home to hear it.

Backup sump pump systems are your only hope of preventing a flood if you lose primary power at home and don't have a generator standing by. You can buy a backup sump pump system separately, or get one included with your primary pump by getting a combination sump pump system.
