Do you need to move large amounts of water quickly? If so, investing in a dewatering pump is one of the most innovative and cost-effective solutions. This type of pump is designed to suck up water and transfer it to areas where it doesn’t cause any harm. They are used for drainage purposes in residential and commercial buildings or underground structures such as basements, tunnels, wells, etc.
Whether your task is big or small, this device has been proven time after time again that work! But with all the choices on the market today, how do you know what will get the job done best? This blog post dedicates every detail for a dewatering pump for your needs.
Dewatering Pump
A dewatering pump is a type of pump used to remove unwanted water in areas with excess moisture. It is commonly used in construction sites, basements, flooded fields, and mines. The pump uses a vacuum to suck out the accumulated water on the ground and send it away through a drainage pipe or tank. Dewatering pumps can also filter and reuse the drained water, which helps reduce costs associated with wastewater disposal.
Basic Component Of Dewatering Pump
A dewatering pump is constructed with several components. Some of the most valuable and essential components of a dewatering pump include:
Pumps
The essential component of a dewatering pump is the pump itself. Pumps come in different materials and sizes to adapt to various needs, from large industrial pumps for heavy-duty applications to small manual pumps for residential or agricultural use. They are designed with impellers that move water quickly through the system and out of the area requiring drainage.
Valves
Valves are used with pumps to ensure optimal flow control, pressure stability, and safety precautions related to flooding risks. Different types of valves can be employed depending on the application requirements, such as gate valves, swing check valves, globe valves, etc.
Discharge Lines
Discharge lines transport water away from where it was being pumped out of and into a reservoir or storage container. They also help balance pressure within the dewatering pumping system by controlling how much fluid is flowing into/out of it at any given time and containing overflow potentials during high output periods.
Control Panels
Control panels connect all components to work smoothly together in tandem upon activation by an outside source (such as a controller) which triggers their movement simultaneously when desired results have been specified by users ahead of time via programmable settings.
While these are the main components of a dewatering pump system, other ancillary equipment may be needed to ensure smooth operation, such as hoses, flow meters, moisture sensors, and more.
Construction Of Dewatering Pump
A dewatering pump is typically constructed with a centrifugal pump and composed of a motor unit, volute, shaft seal, impeller, and diffuser. The motor turns the shaft which spins the impeller at high speeds to move water through the volute. This creates an area of low pressure within the volute that draws water in from around it. The diffuser then helps further reduce stress on the liquid being pumped out by allowing it to flow into a larger area before exiting via the pump outlet.
How Does a Dewatering Pump Work?
A dewatering pump removes water from an area by siphoning it away. It creates negative pressure in the area and draws water up into the suction line, then out of the discharge nozzle. Generally, some filter traps solids while allowing liquids to pass through. This can be done with a submersible pump or as part of a more extensive mechanical system involving pumps and filters combined with valves and tanks.
Dewatering pumps help remove water from construction sites; drain lakes and ponds; empty swimming pools, hot tubs, or aquariums; or for collecting runoff during wet weather events such as floods.
Types Of Dewatering Pump
The types of dewatering pumps include the centrifugal, diaphragm, and progressive cavity pumps. Centrifugal pumps use a spinning impeller to generate pressure, generally used for high-capacity water removal in construction and industrial sites. Diaphragm pumps use a rubber membrane to create suction, drawing the water out of a chamber.
Finally, progressive cavity pumps move fluid in an intermittent motion which is excellent for applications with solids or wastewater with high concentrations of suspended particles.
Final Words
A dewatering pump is a helpful tool for removing water from flooded areas. Dewatering pumps come in various sizes and styles, so choosing the best suited for your needs is essential.
