There are different types of pumps on the market that are made and designed for specific applications. One of these pumps that has many uses is the Sump Pump. We will discuss what a Sump Pump is and what its uses are in this article. Sump Pumps are from the group of centrifugal pumps.
These pumps are used to transport and pump slurry with solid and suspended particles and long fibers such as muddy water, contaminated water, fluids with abrasive particles and industrial and domestic wastewater. In general, Sump Pumps are responsible for transporting thick water.
Thick water is water with impurities such as mud, fine sand particles, fine waste and settled sludge. Sump Pumps are also called skimmer pumps, sewage pumps, thickener pumps, electro-slurry pumps and mud pumps.(The best Cordless Pruning Shear)
Since the Sump Pump is mainly driven by electric motors, they are also called Electro Sump Pump or EPS pump. These pumps consist of a centrifugal pump with a vertical shaft in which the pressure of the fluid discharged from the pump depends on the rotation of the impellers. The electric motor in the Sump Pump drives the pump shaft and provides kinetic energy to transport fluids.
The electric motors used in sludge pumps are of two types: single-phase and three-phase. The rotation speed of the electric motors is 900, 1500 or 3000 rpm. Lower-speed pumps are used to pump thicker fluids. Mechanical sealing is used in the Sump Pump to prevent water from entering the motor.

Dry and Submerged Sump Pump:
Sump Pump is produced in two types: dry and submerged.
Submersible Sump Pump:
Submersible Sump Pump has an outlet diameter of 4 cm to 50 cm.
Submersible Sump Pump is used in fixed and mobile installation.
The protection degree of submersible sumps is IP68, so they can be completely immersed in fluids.
The passage of fluids around the sealed electromotor cools the device and increases its lifespan.(Drill Saw Adapter)
Dry Sump Pump:
In this type of Sump Pump, the electromotor and pump are connected through a coupling.
The electromotor is located at the desired height and outside the fluid, and only the pump is immersed in the fluid.
The motor and pump can be easily separated.
There are three types of Sump Pumps available in terms of material:
To choose the best option for the Sump Pump, it is best to pay attention to the motor power, the diameter of the pump inlet and outlet, and the pump water flow rate. To choose the type of Sump Pump, it is best to first pay attention to the type of fluid and sludge that needs to be moved.
Cast Iron Sump Pump:
The body of these pumps is made of cast iron. Cast iron sludge pumps are cheaper, more popular, and more widely used than steel sludge pumps. This type of pump is used for high-concentration, non-corrosive water. Cast iron sludge pumps do not have as much resistance to corrosion and acidity as steel pumps.
Steel Sump Pump:
In corrosive and acidic water, it is better to use a steel Sump Pump. These pumps are used in two types: single-phase and three-phase.
Bronze Sump Pump:
The bronze sludge pump is used to pump salt water or seawater. This type of pump is used less than the other two types.(The 10 Best Garden Hoses of 2024, Tested and Reviewed)
Sump Pump with Crusher:
A Sump Pump with Crusher is a type of sludge pump that has blades in its opening that are used to crush all kinds of long fibers, fabrics, wood, plastic, etc., so that the pump channels are not blocked during pumping or moving fluids.
Pneumatic Sump Pump and Explosion-Proof EX Sludge Pump:
Pneumatic sludge pumps and explosion-proof EX sludge pumps with cast iron or steel bodies are used to pump chemical, flammable and explosive fluids, and petroleum derivatives.
Floater in Sump Pump:
When the fluid falls below the pump level, the pump heats up, which damages the sludge pump’s electric motor. To prevent damage to the pump, a device called a floater is connected to the Sump Pump, which is responsible for turning the pump on and off. When the fluid level falls below the pump level, the floater cuts off the power to the pump. The floater is mainly installed on single-phase sump pumps.
Sump Pump Impeller:
Impellets are available in semi-open or fully open, fully closed, single-channel or dual-channel types and in terms of shape in vortex impellers, eddy current impellers, impellers with cutting blades. The shape and structure of an impeller depends on the type of fluid being moved, its concentration, and the amount and shape of suspended particles.
The material of the impellers is selected from three materials depending on the type of fluid: steel, cast iron, and bronze. The fluid concentration must be such that the impellers can circulate. If the concentration of suspended particles is higher, a suitable screen is used.
Sump Pump Application:
Pumping clean water
Rainwater drainage
Sewage well drainage
Pool dredging
Well dredging and sludge removal
Industrial and domestic sewage pumping stations
Garden and greenhouse irrigation
Activated sludge
Screened sewage
Long fiber sewage
Industrial sewage
Industrial sewage sludge with water
Fish and shrimp farms
Water features and fountains
Pumping slurry and thin construction materials
The most important questions from users
1-When do I need a slurry pump?
Answer: When your basement is flooded and has no way out. For transporting concrete and grout for foundations – in agriculture for irrigation of contaminated water and for transporting industrial waste.
2-Can a sump pump be used to drain toilet waste?
Answer: No! Unless you use a special model that is specifically designed for this purpose, if you want to use it for sewage, you should use the type that has a shredder to break down tissues and large items into small particles.
3-What is the difference between a sump pump and a water pump?
A water pump is for liquids, but a sump pump pumps both liquids and small solids such as sand and gravel.
