Knowing the limitations of your equipment can help you plan your construction project accurately. A trash water pump is irreplaceable when it comes to soiled excavations. However, not all trash pumps are suited to the task of extracting fouled water.
When choosing between trash and semi-trash water pump, it’s important to consider the amount, size, and nature of debris the equipment has to deal with. In order to understand how well the pumps can work, let’s discuss their limitations.
Different Types of Trash Water Pumps
Even when you’ve settled for a trash pump, you are faced with different types to choose from:
Semi-trash pump – you can save some time and money if your project requires a semi-trash pump instead of a trash pump. It’s a great choice if you have muddy or sandy fluids to work with. These pumps are very common and cost less than their trash counterparts.
Limitation: Semi-trash water pumps can only deal with small solids under about 2 cm in diameter.
Submersible Trash Pump – if you need to submerge the pump into the fluid to get the job done, you need a submersible trash water pump. This pump can prevent pump cavitation. Unlike other pump types, it pushes the fluid out rather than pulling it upward. These pumps can work with viscous materials. They are great for moving sand at the bottom of a pool.
Limitation: Submersible trash pumps are created for specific projects and are useless for regular excavation pumping.
Diaphragm Trash Pump – works in a different manner than other trash pump types, which use centrifugal force. This pump is equipped with a diaphragm, which by being pushed up and down, creates a vacuum effect and sucks the water out. This is a heavy-duty pump, which is used whenever you can’t determine the degree of water contamination. It can pump debris up to 5 cm in diameter.
Limitation: diaphragm trash pumps are very expensive (about four times more expensive than semi-trash pumps) and work much slower than other trash pump types.
Other Factors To Consider
- Portability – The majority of trash pumps are equipped with handles for easy portability. If your project requires using the pump at different places, it must be easy to carry around.
- Self-priming – A high-quality trash water pump should be self-priming. It should work without the operator bringing the liquid into the system.
- Adjustable speed – Some pipes offer the option of speed adjustment, which may be useful at some construction sites.
- Flow rate – Describes how much litres the pump can discharge per minute.
