Reliable and energy-efficient wastewater pumping
Pumping wastewater is challenging. In addition to all states of water, pumps must be robust enough to ensure large solids, rags and fibers can pass freely without causing unwanted downtime and extra maintenance. The SE 12-42 hp range of wastewater pumps from Grundfos are designed to optimize your system performance.
The SE 12-42 hp range of submersible wastewater pumps from Grundfos feature the following three hydraulic concepts:
- Grundfos Open S-tube® semi-open impeller hydraulics (offered for SE/SL pumps fitted with Superhigh -or High head hydraulics. Open S-tube® semi-open impellers provide high efficiency over a wide operating range. They can be trimmed to meet a specific duty point, and SE pumps fitted with Open S-tube® impellers are the ideal solution for medium to extreme contamination of wastewater.
- Grundfos closed S-tube® hydraulics (offered for SE1/SE2/SL1/SL2 pumps fitted with Superhigh -, High -, Medium -, Low and Extra low head hydraulics) or S-tube® closed impellers provide large free passage and high efficiency. SE pumps fitted with the closed S-tube® impeller are ideal for low to medium contaminated wastewater.
- SuperVortex free-flow hydraulics (offered for SEV/SLV pumps). SuperVortex free-flow impellers are ideal for challenging applications with high abrasives content or long fibrous materials.
When combined with intelligent controls and high-efficiency IEC and IE3 motor components, the SE 12-42 hp range of pumps provide an ideal solution for challenging wastewater applications.
Submersible Wastewater Pumps & Controls for Modern Demands
Grundfos’ range of grinders, submersible wastewater pumps (from 1 to 42 hp) and control panels are designed to stand up to the toughest applications, reduce energy consumption and allow for simple maintenance. See why our solutions are different.
Learn how Harris County Reduced Pump Clogging by 90%
Four SE submersible pumps were used by Harris County, Texas in a retrofit application. Thanks to the SE’s S-Tube impeller, the county was able to reduce clogging by 90%. Other advanced features like the pump's Smart Trim System allowed the equipment to be serviced in-house, lowering maintenance costs by 61% and ensuring the pump was always running at maximum efficiency.

Reduce Clogs & Optimize Pump Efficiency with the S-TUBE® Impeller
Learn how the innovative, non-clogging capabilities of our S-TUBE® impeller prevent rags and fibrous materials from getting stuck in the volute. The S-tube also delivers greater hydraulic efficiency when compared to any other type of wastewater impeller, resulting in the lowest life cycle cost, trouble-free operation, and best-in-class non-clogging capabilities.
2-Pole VS. 4-Pole Motors for Submersible Solids Handling Pumps
New technologies have altered how we view mechanical and hydraulic challenges. Historically, in the United States, there has been a broad tendency to specify 4-pole nominal 1750 rpm motors for use on submersible solids handling pumps, however, this approach is changing. Many engineers now prefer 2-pole motors for lower flow/higher head applications. Learn about the factors you should consider when selecting a motor type for your application.
We’re Experts on Pump Controls
A drive can help lower energy consumption at wastewater pumping stations, but a drive on its own is not enough. For an optimized system you also need an intelligent and complete wastewater control and monitoring solution.
The Grundfos CU 362 (Dedicated Controls), was developed specifically for network pumping stations and allows for system measurement and calculation, and integration with other monitoring, control, and energy optimizing equipment.
