Price list for Grundfos pumps

In March 2014, Grundfos modernized its line of well pumps. The outdated SPO pumps have been replaced by new Grundfos SBA and SB well pumps. The new series pumps use significantly more polymer materials, which made it possible to significantly reduce the price of the pump for the consumer. In addition, a number of new innovations have appeared.

First of all, the new well pumps have a model 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 allows the fence to be taken almost from the very surface, avoiding sand and silt being drawn into it. Meanwhile, the manufacturer recommends using these pumps in cases where the distance from the pump to the wall of the tank/well is 1.5 meters or more, which is usually not feasible in ordinary wells. Otherwise, the hose may rest against the walls (or you will have to shorten it). Pumps in this series have the designation AW in their name.

So, what is the difference between Grundfos SBA pumps and Grundfos SB and Grundfos SPO?

Well pumps Grundfos SB are essentially a continuation of the SPO series. They are presented in 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 pumps SBAs are represented by the following models:

• Grundfos SBA 3-35 A- RUB 24,680 - with float switch and suction grille
• Grundfos SBA 3-35 AW- RUB 27,650 - with float switch, with side intake through a hose with a float
• Grundfos SBA 3-45 A- RUB 24,500 - with float switch and suction grille
• Grundfos SBA 3-45 AW- RUR 29,190 - with float switch, with side intake through a hose with a float

The new pumps are now mostly made of polymer, including the impellers, stainless steel suction screen and motor shaft. It is worth noting that the perforation of the grille 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 connecting a hose.

SB and SBA pumps are supplied in 2 sizes with a maximum head of 35 and 45 meters and in three different designs:

M– without float switch,
A– with float switch,
A.W.– with float switch and suction hose with float and filter.

Temperature of the pumped liquid: from 0°С to +40°С

Electrical power supply parameters: 50Hz, 1*240V

Power cable length: 15 m with Schuko plug

The maximum pump flow is 6 cubic meters/hour

*Designed for pumping clean water.
**SB pumps can be controlled using a float switch or PM1/PM2 automation unit.

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 the cameras are made of 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 have a service life of 10 years or more, 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 an intake strainer and a 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 stainless steel have a mesh 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 constantly takes the most close place to the surface of the water, then when it reaches the minimum water level in the well, the contact is broken and the pump stops working.

The most attractive price at submersible well pump .

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.

How to choose a Grundfos well pump.

Wells and wells are by far the most popular source of water in a private home or country house. Drilling a well is more difficult and more expensive than equipping a well, however, the issue is not only about cost.
The depth of the wells starts from 5 m and can reach 15 m, depending on the passage of the aquifer. The well is budget and effective option for carrying water to a house or country house. The water supply from the well is uninterrupted. This method is affordable and easy to use and can last at least 50 years.
To supply water simply and comfortably, you need to buy a submersible pump equipped with a filter. Such a unit will become a universal assistant for every homeowner and summer resident, since it can be used not only to lift water, but also to water the garden, garden and lawns, pump water from the pool and fill it with water, pump rain water, pump water from flooded rooms (basements, cellars, ground floors). Surely you are interested in: how to choose a reliable and high-quality pump for a well and where to buy a similar unit in Moscow?

The variety of well devices is quite large and it is quite difficult to understand this variety without the help of a specialist. Before you make a choice, you need to know exactly the depth of the well or borehole. However, there are several points that will help you navigate and choose the appropriate modification:

• power,
• performance,
• presence of overheating protection,
• presence of a float switch,
• body material.

There are several classifications of units:

• submersible,
• superficial,
• vibration,
• centrifugal,
• pumping stations.

What type of equipment is preferable for home and garden use? Experts unanimously recommend purchasing submersible devices for wells. Equipment of this type has a cylindrical shape, is made of stainless steel, and is equipped with one-, two- and three-phase electric motors.

Devices for raising water operate in difficult conditions and in almost uninterrupted mode, so they are very important nuance is the presence of overheating protection. Since the water level in sources is not stable and periodically drops, the pump must be protected against dry running.

The most durable are well pumps equipped with a float; if the water level is insufficient, the float switch stops the operation of the unit, and after the water level has stabilized, it automatically turns it on.
