A wastewater pump, also known as a sewage pump, is a type of pump used to transport wastewater or sewage from one location to another. Wastewater pumps are typically used in municipal sewage systems, industrial applications, and other settings where wastewater needs to be transported from lower to higher elevations or over long distances.
Wastewater pumps come in many different types and sizes, but most operate by creating pressure to move wastewater through a pipeline. Some common types of wastewater pumps include centrifugal pumps, positive displacement pumps, and grinder pumps.
Centrifugal pumps use an impeller to generate centrifugal force, which creates pressure and moves the wastewater through the pipeline. Positive displacement pumps, on the other hand, use a piston or other mechanism to displace the wastewater and move it through the pipeline. Grinder pumps are a specialized type of wastewater pump that are designed to grind up solid waste and then pump it through the pipeline.
Wastewater pumps are used to move wastewater from one location to another, typically from a lower to a higher elevation or from a more remote location to a treatment facility. The basic operation of a wastewater pumps can be described as follows:
1. Inlet: Wastewater flows into the pump from a collection system or holding tank through an inlet pipe.
2. Impeller: The pump contains an impeller, which is a rotating component with curved blades. As the impeller rotates, it creates a low-pressure area at the center of the impeller and a high-pressure area at the outer edge. This pressure difference causes the wastewater to be drawn into the center of the impeller and then forced outward toward the outlet.
3. Outlet: The wastewater is forced out of the pump through an outlet pipe, which carries it to its destination.
4. Check valve: A check valve may be installed in the outlet pipe to prevent the backflow of wastewater into the pump when it is not operating.
5. Control system: A control system may be used to monitor the pump’s operation and automatically turn it on and off as needed.
The S-WN pumps, which are dry-installed, have the flexibility to be mounted horizontally or vertically. The design of these pumps is compact and versatile, making them suitable for a wide range of service conditions. These pumps, specifically designed for wastewater, are powered by an energy-efficient, air-cooled IEC motor and are connected to the piping via flanges located on both suction and discharge sides.
Our product line includes a range of pumps, from the smaller S-WN1 to the larger S-WN5, which can handle everything from light industrial effluents to heavy-duty wastewater projects from urban areas and industries. These pumps can handle flow rates ranging from 68m³/h to 4000 m³/h, and can be connected to piping with DN80 to DN600 connections.
To meet your specific requirements, the S-WN pumps can be customized by adjusting the motor size and impeller type, allowing them to be used in a variety of applications.

1. Unique Cartridge Seals & Easy Maintenance
Our double mechanical seals are one-of-a-kind and come in a cartridge that is easy to use, allowing seal replacement without requiring any specialized tools. This feature eliminates the possibility of incorrect installation, making it safe and convenient installation.
2. Fast Lock Latch Bolt
The Greenleading S-WN-line boasts the exceptional fast lock latch bolts feature that simplifies the separation of the pump from the motor. Service staff highly favor this feature since it significantly reduces maintenance downtime.
3. Higher Efficiency with Adjustable Wear-ring
The hydraulic loss between the impeller and the wear-ring is reduced thanks to the wear-ring feature. It can be regularly adjusted to optimize the pump’s efficiency.
4. Premium Efficiency Motor
Incorporating a Premium Efficiency motor as a standard is the most effective method to minimize energy consumption. It enhances the efficiency of the system while also maintaining the same risk of blockage.
This air-cooled IEC motor is designed to handle wastewater and sewage pumping applications, ranging from 2.2 to 200 kW. It’s suitable for various settings, including domestic, commercial, industrial, and municipal areas.
