INSCMagazine: Get Social!

A trash pump is equipment commonly used for dewatering purposes. Dewatering refers to an engineering application in which water is removed from a site or mine to create a safe working environment for all. Whether it is a standing pool of water at a construction site or water mixed in soil at an underground property, removing water is necessary to keep the site safe and hygienic. Dewatering is a time-consuming process, but it can be made simple with the use of the right kind of trash pumps.

What is a Trash Pump?


Trash pumps are heavy-duty pumps designed to remove water from sites where the water contains big amounts of trash. Trash refers to anything ranging from dead leaves, rocks, dirt, branches to other solid materials. These pumps are available in a variety of sizes, styles, and designs, and can remove hundreds of litres per minute if installed properly and maintained. Most of these pumps have a centrifugal system with a bladed rotating impeller that allows water to flow towards the discharge. They can handle solid as well as semi-solid materials during the dewatering process. Usually, these pumps are submerged in water and are often powered by electricity or gas.

Types of Trash Pumps

These pumps can be of four different types:

Sanitary pump: This pump is used in places where a higher level of hygiene and sanitation is required, such as breweries, biotech companies, pharmaceuticals, or food factories. It can even remove slurries.

Syringe pump: This pump can process materials with the exact rate of flow at accurate intervals of time. It can be a withdrawal pump that removes fluid or an infusion pump that can process liquids at specific pressures.

Positive displacement pump: This pump uses devices like gears, pistons, and diaphragms to move liquids. When the liquid is pumped into a cavity and then pumped again, it creates a vacuum which sucks in fluids. It is highly effective to move viscous fluids that have great pressure.

Progressive cavity pump: This pump can be used to move slurries and even liquids that have suspended solids. It moves the fluids from the suction side to the discharge side and then transfers it through a pipeline or to a storage tank. These trash pumps can also move slow and dense viscous fluids and materials efficiently. It is often used in places that need greater sanitation and sterilization, as they are easy to clean and operate.

Things to Consider While Buying a Trash Pump

While buying a trash pump, you need to keep several things in mind, including the following:

Quality: There are several manufacturers who produce trash pumps in the market, but you need to choose one that is durable, high performing and long-lasting. You can rely on brand names but don’t forget to read their reviews before making your purchase.

Purpose: The purpose of using the trash pump and the type of water you want to dewater would also influence your selection. Give attention to the capacity of the pump too to handle your project.

Features: You can look for certain features in the pump such as dry running, adjustable speed settings, pressure gauges, power backup, slurry gate, etc.

Price: Even if you are buying a branded trash pump, it should be priced reasonably as per industry standards. Compare a few pumps in the market and make an informed decision regarding its quality and price.

With all the information that we have given above, you can make a wise selection regarding trash pumps. Finally, you need to choose the one that best suits your purpose and project requirements. It should fall within your budget and it should have the features that you want in your pump.
