Grundfos SB is a submersible well pump for water supply systems. It is used for efficient pumping of clean water from wells and rain storage tanks.
The well pump is available in two basic designs:
- with built-in mesh filter (perforation 1 mm);
- with side entry, which includes a flexible suction hose and a floating mesh filter (perforation 1 mm).
In both versions, the Grundfos SB pump can be supplied with or without a float switch. The float switch can be used for automatic operation or for dry-running protection.
Pump options
A- built-in strainer with float switch.
M- built-in strainer without float switch.
A.W.- float filter with float switch.

Features and Benefits
Silent operation
When submerged, the Grundfos SB pump runs silently and is therefore a cost-effective alternative to non-submersible pumps.
High reliability
The Grundfos SB well pump is made of composite materials and of stainless steel corrosion resistant. In addition, the pump is equipped with a stainless steel filter that prevents large particles from getting inside.
Built-in protection
The pump is equipped with thermal overload protection.
Float strainer
The float strainer model sucks water just below the surface, where the water is clean and free of solids.
Technical details
Quick Selection Guide
If the distance from the wall of the tank (well) to the pump is more than 1.5 meters, it is recommended to use a model with a side entrance. If the distance from the wall of the tank (well) to the pump is less than 1.5 meters, a model with a strainer is recommended.
Selection of the size of the pump depending on the application:
Additional advantages when installing well pumps with PM1 and PM2 automation units
- Installation of automation units PM1 and PM2 right in the house: the ability to control the operation of the pump.
- Automatic pump operation.
- Dry run protection.
- Automatic restart.
- Extended functionality when installed with PM2.
Permits and markings
The Grundfos SB pump has the following marking: EAC (Customs Union).
Submersible pump SB and submersible automatic installation with an integrated SBA control system are designed for the water supply of private houses. SBA pumping units do not require additional pump controls, making them ideal for water supply systems from wells and tanks (rainwater tanks that serve as an additional source of industrial water for household appliances, watering), disposal of sewage in private cottages and summer houses.
Unique Benefits
- Unique equipment
Everything necessary elements controls (flow sensor, pressure switch, non-return valve) are already built into the SBA pumping unit - Automatic start
The SBA submersible pumping unit automatically starts when water is supplied. The SBA pumping unit without float switch automatically restarts every 24 hours.
The SB pump stops when the minimum water level is reached. Restart is carried out using external control devices.
The pump will automatically start as soon as you open the tap, and turn off after you close it. - Built-in dry run protection
The automatic SBA unit has a built-in dry-running protection that will turn on in the event of a lack of pumped liquid. Float switch versions are available for all pump models. - Long service life
The Grundfos float switch prevents air from entering the system due to dry running. - overheat protection
built-in thermal protection immediately stops the pump in case of overheating. When the permissible temperature is reached, the pump automatically restarts. - Clog protection
Stainless steel mesh filter prevents large particles (more than 1 mm) from getting inside - Corrosion resistance
Submersible pumps and pumping units are made of composite materials and stainless steel, which ensures corrosion resistance. - Pumping clean water
The floating strainer draws water just below the surface, where the water is clearest and free of large particles and solids. - Accessories
The SB pumps can be controlled by a float switch or a PM1/PM2 automation unit. - High quality materials
The pumps use reliable metal threaded connections. - Silent operation
When submerged, SB/SBA units operate silently and are an alternative to non-submersible pumps.
The SB and SBA pumps are available in 2 sizes with a maximum head of 35 and 45 meters and in three different versions:
M– without float switch,
A- with float switch
A.W.– with float switch and suction hose with float and filter.
Fluid temperature: from 0°С to +40°С
Parameters of the electrical supply network: 50Hz, 1*240V
Power cable length: 15 m with Schuko plug
The maximum flow of the pumps is 6 m3/h
*Designed for pumping clean water.
** SB pumps can be controlled by a float switch or a PM1/PM2 automation unit.

Price list for Grundfos pumps
In March 2014, Grundfos upgraded its range of well pumps. Outdated SPO pumps replaced by new well pumps Grundfos SBA and SB. In pumps new series much more used polymer materials, which allowed to significantly reduce the price of the pump for the consumer. In addition, there are a number of other innovations.
First of all, a model has appeared in the new well pumps that allows water to be drawn close to the surface. Suction is carried out through a hose, to the end of which a float is attached. This innovation makes it possible to fence almost from the very surface, avoiding sand and silt being drawn in. Meanwhile, the manufacturer recommends using these pumps when the distance from the pump to the tank/well wall is 1.5 meters or more, which is usually not feasible in conventional wells. Otherwise, the hose may rest against the walls (or it will have to be shortened). Pumps of this series have the designation AW in the name.
So what is the difference Grundfos pumps SBA from Grundfos SB and from Grundfos SPO?
Grundfos SB well pumps are essentially a continuation of the SPO series. They are represented by 6 models:
Grundfos SBA well pumps, unlike the SB series, have built-in automation: a pressure switch and a flow sensor and are ready for use immediately after connection.
Grundfos SBA pumps are available in the following models:
- Grundfos SBA 3-35 A- 24680 rubles - with a float switch and a suction grate
- Grundfos SBA 3-35AW- 27650 rubles - with a float switch, with a side intake through a hose with a float
- Grundfos SBA 3-45 A- 24500 rubles - with a float switch and a suction grate
- Grundfos SBA 3-45AW- 29190 rubles - with a float switch, with a side intake through a hose with a float
New pumps now for the most part consist of a polymer, including impellers, stainless steel suction grate and motor shaft. It is worth noting that the perforation of the grating has noticeably decreased and is now 1 mm, which will allow even small grains of sand to be retained. In addition, all models are equipped with a removable check valve and a universal herringbone adapter for hose connection.
