Water pumps are meant to pump clear water. But when you introduce debris and other solids to the mix, things can get clogged or damage your pump. That's where trash pumps come in.
You can find more information on our web, so please take a look.
They're capable of passing water that other pumps just can't handle. There are many types of water pumps you'll need to choose from, depending on your situation.
In this article, you'll learn about the different types of trash pumps and which applications work best for each.
If you simply need to pump small amounts of greywater around the home with solids in it (like in flooded window wells with sand and leaves), then an electric submersible trash pump may be right for you.
They are as easy to use as attaching the hose and dropping it wherever compact areas you may need it. Just keep in mind that the function of these pumps are extremely limited, so if you need to move large amounts of dirty water with solids involved, we definitely recommend a semi-trash pump or better.
Semi-trash pumps get their name from the fact they can pass small debris, but not much more than that. The pump housing just isn't large enough to pass larger items.
Semi-trash pumps are typically used to pump clean or slightly muddy and sandy water.
The largest items any of our semi-trash pumps can pass is about 5/8 of an inch. You'll want to use a hose with a strainer so the hose doesn't get clogged with any items too big to pass through. The strainer just sifts the debris that the pump can handle and leaves out the stuff that's too big.
Trash pumps are made to handle debris and solids such as leaves, pebbles, and twigs. With larger impeller veins and pump housing, trash pumps can pass solids like those mentioned above.
The pump does not grind these up as they enter the impeller, but leaves them intact and sends them on their way. You'll want to use a hose with a strainer for trash pumps too. In the event the pump does get clogged though, there are easy cleanouts, which you can open up by hand and remove any items too big.
Diaphragm pumps work entirely differently than other trash pumps. Instead of using centrifugal force, the pump has a diaphragm that is pushed up and down, creating a vacuum effect.
When the diaphragm goes up, it creates a vacuum, sucking in water. When the diaphragm is pushed down, it ejects the water that was just suctioned into the pump. It essentially acts like a piston in a combustion engine, alternately drawing in and then ejecting out.
Diaphragm pumps are most commonly used to pump sludge and extremely abrasive liquids. A common example would be draining a pond because it can handle the muck and mud on the bottom, as well as the water, leaves, and weeds.

PTO trash pumps are beloved by farmers and workers in the agricultural industry because they attach to a tractor's power take-off driveshaft and are powered by the tractor's massive gas engine. They attach quickly, prime in seconds, and are virtually maintenance-free because they don't have an engine of their own.

Sometimes you need the power of ten industrial trash pumps in places you can't really carry it to. The natural solution is an industrial-grade, trailer-mounted trash pump. You no longer have to imagine a pump that boasts a 6" inlet size, can pump up to 2,750 GPM (gallons per minute) and can lift that water 150 feet high with these behemoths.
Armed with a venturi dry prime centrifugal pump and a water-cooled, turbo-charged diesel engine, the possibilities are virtually endless with industrial, top-tier trash pumps like these. Don't let the price tag fool you, they're worth every penny for the toughest water pumping applications on construction sites, mining operations, sewer bypass projects, and much more.
When you need to move water efficiently from one area to another, water transfer pumps are the tool you’ll need to get the job done right the first time. Water transfer pumps are versatile devices designed to handle a large variety of water relocation tasks, making them essential tools in various scenarios. Let’s explore what water transfer pumps are, the various types of water transfer pumps, and how you can best utilize them for their effective and efficient solutions.
Water transfer pumps are mechanical devices used to transfer water from one location to another. Some of the purposes for water transfer pumps consist of draining pools, removing water from basements, and irrigation efforts. Water transfer pumps are known for their fantastic ability to quickly move large volumes of water with ease.
Below are the different types of water transfer pumps available. Each water transfer pump is suited to specific tasks based on their unique design and capability:
Centrifugal Pumps: Centrifugal pumps are the most common type of water transfer pump. A centrifugal water transfer pump utilizes a rotating impeller to create a vacuum and centrifugal force to efficiently move water. A centrifugal pump is ideal for transferring clean water, as they tend to clog if debris is present.
Submersible Pumps: Submersible pumps are designed to be placed directly within the water itself. Submersible pumps are completely sealed against all fluids and are very effective in deep water scenarios.
Trash Pumps: Trash pumps are different when compared to standard water transfer pumps. Trash pumps are designed to handle water containing large debris. Trash pumps have larger intake and discharge ports. With these larger intake and discharge ports, trash pumps are great for scenarios with large levels of debris or runoff.
High-Pressure Pumps: High-pressure pumps are specifically designed to move water over longer distances or to higher elevations. These types of pumps are often found in areas with hilly landscapes where the need for water transfers from low elevation to high elevation is necessary.
Here’s a basic guide to get you started: To use a water transfer pump, it’s important to understand the specific needs of your project and the type of pump you’re using. Here’s a breakdown of what to do:
Select the Right Pump: Choose a pump based on the average volume of water you need to move on a daily basis and the nature of the liquid which is being moved. Ensure the pump is suitable for the water’s cleanliness or debris level, as some pumps may need to be selected based on the job being performed.
Set Up the Pump: For a centrifugal pump, you'll need to place the pump near the water source with hoses or pipes securely attached to the intake and discharge ports. You should ensure all connections are tight to prevent any possible air leaks.
Prime the Pump: Most centrifugal water transfer pumps require priming prior to use. This involves filling the pump and intake hose with water to create the necessary vacuum for water movement. Verify this information against the manufacturer’s guide for specific priming instructions for your pump.
Start the Pump: Turn on the pump and monitor its operation to ensure water flows smoothly. Checking for any leaks or drops in pressure which may indicate problems is a crucial step.
Maintain Your Pump: Regular maintenance is key to extending the life of your water transfer pump. This maintenance includes checking seals and bearings, cleaning any intake and discharge ports, and ensuring the motor is in good working order; functioning as it should with efficient performance.
