The SB and SBA pump is a submersible booster pump for the pumping of clean water. It is especially suitable for rainwater applications and private wells. The pump is available in two versions:

SB

The Grundfos SB is a submersible pump for the pumping of clean water. It is designed for use in domestic applications. The pump itself is very silent, and when installed underground in a rainwater collecting tank or well, noise will never become an issue. The SB pump requires an external controller, like Pressure Manager, for automatic operation.

Features and benefits

• Flexible selection – Pump + controller
• Complete control and monitoring
• Easily accessible controller – for service & replacement

SBA

The new Grundfos SBA is a complete all-in-one unit. It is built on the proven SB platform, but comes with an integrated control unit – eliminating the need for an external pump controller.

The SBA is literally a plug- and pump solution. Once installed and connected to the piping, all you need to do is switch on the pump.

Features and benefits

• Easy selection – one unit
• Easy installation – one unit
• Flexible installation – no controller inside the house

All SB and SBA pumps are available in two main variants

• With integrated suction strainer (1 mm mesh)
• Or with side inlet/flexible suction hose with floating suction strainer (1 mm mesh).

All variants are available with or without float switch:

The float switch offers automatic operation and dryrun protection, stop at low water level, ensuring that surface fragments do not enter the strainer.

Applications

The SB and SBA pump is a submersible booster pump for the pumping of clean water. It is especially suitable for rainwater applications.

Features and benefits

• Noiseless operation
• High reliability
• Integrated protection.
• Floating suction strainer
  The model with floating suction strainer always draws the water from just below the water surface where the water is clean and free from solid particles.

Additional features of the SBA:

• Simplicity – all-in-one unit
• Easy installation – no external control unit

Unilift KP pumps are submersible drainage pumps for pumping drain water or grey wastewater. The KP is suitable for both temporary and permanent free-standing installation or installation in collecting tanks.

All Unilift KP pumps can be supplied with or without a level switch for automatic or manual operation. The strainer is clipped onto the pump housing and can easily be removed for cleaning and maintenance.

The robust design – all metal parts in contact with the pumped liquid are made of stainless steel – makes it ideal for rough environments. The outer casing is made in one piece. The motor is a canned motor with liquid-filled rotor chamber and water-lubricated bearings.

The motor incorporates automatic overload protection which cuts out the motor in the event of overload. When it has cooled to normal temperature the motor restarts automatically.
Applications
The Unilift KP pumps are designed for the pumping of:

• Water from rivers and lakes
• Rainwater, drainage water and water from flooding
• Water for filling/emptying containers, ponds, tanks, etc.
• Effluents from showers, washing machines and sinks below sewer level
• Pool water
• Ditch drainage water
• Lowering groundwater
• Domestic effluents from septic and sludge-treating systems
• Effluents from viaducts, underpasses, etc.

Grundfos’ new range of GHP (Grundfos Hygienic self-Priming) pumps takes efficiency and durability to new levels in sanitary processes.

The pumps are based on the well-known HILGE technology and are further optimised to offer reliable operation even under the tough conditions encountered in cleaning processes.

The single-stage self-priming GHP pumps combine the best of the F&B-HYGIA end-suction pumps with the reliable HILGE technology. The result is an optimised pump range that comes with increased efficiency compared to traditional side-channel pumps and can be counted on for long operational life.

One pump – More applications

Due to the robust construction of the new GHP pumps they are able to handle liquids with a high content of air as is the case in CIP return systems.

In effect, this means that the same pump can be used for product conveyance as well as for the cleaning processes. Compared to side-channel pumps, GHP pumps are also less sensitive to handling products containing particles.

Low noise operation

The GHP pumps feature a new, unique hydraulic technology that allows the impeller to be adjusted to accommodate exact duty-point requirements.

This translates into a noise level significantly lower than compared to traditional side-channel pumps.

Specially designed for sanitary applications

The all-stainless steel GHP pumps have been specially designed for trouble-free operation in sanitary processes such as:

•  Cleaning processes (CIP return)
•   Evacuation of tanks and pipes
•   Pumping liquids with a high gas content
•   Pumping liquids in Food and Beverage industries.

The Grundfos HS horizontal split case pump is a single-stage, non-self-priming, between bearing, centrifugal volute pump. The axially split design allows easy removal of the top casing and access to the pump components (bearings, wear rings, impeller, and shaft seal) without disturbing the motor or pipework.
The independent bearing housing allows for ease of maintenance without removing the top casing. The double volute design reduces the radial load on the shaft, extending component life, minimising vibration and providing quiet operation.

The HS pump also offers high pump efficiencies throughout the range.  High energy efficiency along with long pump life and easy maintenance add up to low life-cycle costs.
The HS pump is available in three configurations – pump with motor and baseframe, pump with baseframe, and bare shaft pump only.
The HS pump is ideal for custom applications and is available in a wide range of variants. The high efficiency and low life cycle costs make the HS ideal for any commercial building, water utility or industrial project.

Applications

Grundfos HS horizontal split case pumps are typically used in these applications:

• Air-conditioning/heating systems
• Public water supply
• District cooling/heating plants
• Cooling systems
• Public waterworks
• Process cooling
• Irrigation.

Features and benefits

• Easy to service: split case design
• Double suction minimises axial load,which extends the life of the wear rings, shaft seals and bearings
• Double volute reduces radial forces and minimises noise and vibration
• Independent bearing housing design allows access to the pump components without removing the top half of the casing
• High energy efficiency
• Low life-cycle costs
• Many product variants available.

CHLORINE DIOXIDE – Effective, Lasting Protection Against all Germs and Biofilms

Chlorine dioxide for long-control of dangerous germs and prevention of biofilm formation.

Chlorine dioxide ( CLO2 ) provides excellent, lasting disinfection for your water. Even if water is not flowing through the pipes, chlorine dioxide prevents germs from building up again thanks to its outstanding sustained-release action. The sterilization process with chlorine dioxide is also taste and odour-free.

Chlorine Dioxide Offers a Wide Range of Other Benefits

As  a bactericide, sporicide , virucide and algicide, chlorine dioxide is in every respect highly effective against all critical and even chlorine resistance germs.

Chlorine dioxide is particularly effective in fighting legionella and prevents biofilm formation and corrosion of water pipeline systems. It removes the nutrient source for these types of hazardous germs, which significantly prologs the duration of the disinfectant effect.

Its disinfection capability very high even in relatively small quantities and is more or less independent of the PH value. Chlorine dioxide can therefore also be used in an alkaline environment with no problem.

The formation of strong-smelling by-production such as trihalogeno methyls (THM), chlorophenols or chloramines that cause irritation to mucous membranes is negligible. This makes chlorine dioxide the disinfectant of choice for processing food and drink.

Disinfection properties : The disinfection effect of chlorine dioxide is very high even if only very small quantities are added.

Generate Your Chlorine Dioxide Directly on Site With Maximum Yield :

Two Methods Have Been Tried And Tested Worldwide And Conform To International Standards

The disinfectant can be generated on site either from chlorine and hydrochloric acid or from chlorite and chlorine. With both these processes, Grundfos Alldos meets the stringent  requirements of DIN EN 12671 for disinfection of drinking water.

The disinfectant yield is up to 95% with both methods. It is used as an aqueous solution containing 0.5 – 3 mg CLO2/I , depending on the application.

1. Hydrochloric Acid / Sodium Chlorite Method :

With the acid dioxide can be generated from diluted or concentrated sodium chlorite and hydrochloric acid solutions depending on the user’s requirements :

Diluted                 : HCL  9%, NaCLO2  7.5%

Concentrate       : HCL  33%, NaCLO2  24.5%

The Chemical Formula :

5 NaCLO2 + 4 HCL  <========è 4 CLO2 + 5 NaCL + 1H2O

1. 2.       Chlorine / Sodium Chlorite Method :

With this particularly cost-effective preparation method, the chemical starting materials are concentrated sodium chlorite solution (24.5%) and chlorine gas ( acidic chlorine solution) dissolved in  water.

The chkorine dioxide is produced according to the chemical formula :

2 NaCLO2 + CL2  <========è 2 CLO2 + 2 NaCL
