Such pumps are used to supply domestic water directly from well to a cottage house, dacha or to your site. The water that needs to be transferred from the well to the room must be at a certain temperature (not higher than 40°C). The SBA series pumps have individual properties that distinguish them from the SB series pumps. Their special feature is the presence of a control unit, which is built into their design. The control unit is a switch on and off (using a sensor and flow), which are already built inside. Based on the above, it follows that the need to connect to Grundfos well pump series S.B.A. additionally a hydraulic tank or other control systems does not make sense. Price such Grundfos well pumps very low, as well as their ease of installation and compactness. For Grundfos well pumps such as S.B.A. and SB series, the same materials were used during assembly: pump housing, base, Working wheel and cameras are made from composite materials. Since the materials from which the pumps are made are very practical and durable, it can be concluded that they are highly corrosive wear resistance and long service life of the pumps. Pumps of both series last for 10 years, and the manufacturer’s warranty is 2 years.

Modifications of such pumps:

1. Pumps with the letter "M" (SB M) - have a strainer that is built into bottom part housings. It serves to collect water;

2. Pumps with the letter “A” after the numbers - with intake mesh filter and with float switch;

3. With the letters AW after the numbers - pumping units with a suction hose with a plastic float buoy.

Mesh filters made of of stainless steel, have a cell size of 1 mm, this completely eliminates the entry of large particles into the structure. The float switch, which is installed on well pumps, controls the operation of the pumps depending on the water level in the well relative to the suction pipe. Because the float always occupies the closest place to the surface of the water, when it reaches the minimum water level in the well, the contact breaks and the pump stops working.

Design

Grundfos SBA and SB – submersible automatic installations and well pumps. The electric motor is located in the upper part of the pump, next to the pump discharge pipe, and is cooled by the pumped water.
The impellers and pump housing are made of high-quality composite materials, the shaft with rotor and the strainer/suction pipe (depending on the version) are made of stainless steel.
SBA units and SB pumps are supplied with an adapter for a pressure port with a G 3/4" or G 1" connection.

Check valve included in SBA and SB:

in SBA units, the check valve is built into the pressure part of the housing;

on SB pumps the check valve is located inside the adapter.

SBA units and SB pumps with a single-phase electric motor have a built-in capacitor, and a float switch can be supplied.

The pump/unit is equipped with a thermal switch and does not require any additional motor protection.

terms of Use

• Temperature of the pumped liquid: from 0°C to +40°C.
• Ambient temperature: from 0 °C to +50 °C.
• Maximum diving depth: 10 m.
• The pump must not run dry.
• The pump should not operate with the valve closed.
• The pump must pump only clean water.

Operating principle

The SBA installation control system ensures automatic start of the pump when water collection begins and automatic stop when water consumption stops. The operation of the SB pump when using a float switch is controlled depending on the water level relative to the suction pipe. Since the float part invariably occupies a position as close as possible to the surface of the water, determined by the length of the cable, when the minimum level is reached and the container or well is emptied, the contact opens and the pump stops working. A pump without a float switch is turned on/off manually or using an external device, for example, automation units PM 1 or PM 2. The SB pump, installed, for example, with an automation unit, switches off in an emergency when “dry running” occurs.

Why are submersible pumps needed?
