Regional creation ensures fast and reliable delivery as well as the possibility to address alternatives for local customers.
1. 2 Grundfos Singapore
Grundfos Singapore (GSI) was set up in 1984, marking a very important level in Grundfos occurrence and target in the Asia Pacific region. It assists the local Singapore market as well as the rising markets in neighbouring countries. GSI is in charge of Grundfos subsidiary sales companies in China, Korea, Hong Kong, Taiwan, Malaysia, Thailand, Indonesia and India. Also, GSI is responsible for developing some of Asia's newer markets such as Sri Lanka, Nepal, Philippines, Vietnam, Laos and Cambodia. In Singapore, they are a leading distributor of pumps and pumping systems to the commercial and domestic building services, professional and OEM (Original Equipment Manufacturer) market segments as well as municipal advancements. GSI also has modern and highly efficient assembly functions, advanced assessment facilities and considerable warehousing facilities. Therefore GSI performs a competent role as the Asia Pacific Regional Distribution Centre. As the regional distribution centre, GSI retains an extensive stock of pumps, components, accessories and service spares, with a complete well worth of S$20mil in value. Presently, GSI operates in 2 factories in Singapore.
With an total annual production of more than 10 million pump models, Grundfos is one of the world's leading pump manufacturers. Circulator pumps (UP), submersible pumps (SP) and centrifugal pumps (CR) are the three major product communities.
Pump is suitable for a particular liquid when is determined by lots of factors like the chloride content, pH value, temps and attentiveness of the pumped fluids and pressure.
2. 1 Centrifugal pump (CR)
2. 1. 1 CR, CRI, CRN
CR, CRI and CRN pumps are vertical multistage centrifugal pumps. The CR pumps consist of two main components which will be the motor unit and the pump unit.
Grundfos CR pumps are available in various sizes and various numbers of levels to supply the movement and pressure required. CR pumps are made for a variety of applications from the pumping of potable drinking water to the pumping of chemicals. The pumps are therefore suited to a wide diversity of pumping systems where the performance and material of the pump meet specific demands. CRI is constructed of lower quality of stainless steel and CRN is constructed of higher level of stainless.
2. 1. 2 CRE, CRIE, CRNE
CRE, CRIE and CRNE pumps are belong to E-pumps family and are built based on CR, CRI, and CRN pumps. CRE is fitted with E-motor, which has a built-in rate of recurrence control with a pressure sensor is connected, to adapt the performance to confirmed requirement.
2. 2 Submersible Pump (SP)
Various SP pumps
The SP pump is a centrifugal pump. The pump consists of an inlet, lots of pump levels and a pump store. Each pump stage creates a pressure difference, and a lot more pressure needed, the greater stages need to be included. A pump stage includes an impeller where the impeller blades transfer energy to this inflatable water in terms of the speed and pressure increase between your pump inlet and electric outlet. Various kinds of submersible pumps such as SP A, SP, SP-G with different sizes range from 4", 6", 8", 10", 12".
2. 3 Circulator Pump (UP)
The composition of circulator pump contains pump housing, impeller, rotor, stainless rotor can, stator and stator cover. Circulator pump provides circulation of cool water and other liquids in chilling and air-conditioning systems.
3. 1 Examples of E-pump applications
Industry uses a sizable volume of pumps in numerous applications for regular pressure, temp and stream such as water resource systems, pressure boosting and commercial uses.
In professional freezing systems, the demand for cooling down is is determined by the amount of water circulated in the machine. In a heavy steam boiler, the level sensor in the pump can keep an eye on and control pump procedure to maintain a consistent level of drinking water in the boiler. E-pump with pressure sensor has been used as dosing like in the chemical substance industry to control of pH-values till the correct mixture percentage is achieved when more liquids are combined. Also, E-pumps with pressure sensor are used for water supply in high-rise properties to ensure a constant pressure even at the best draw-off point. It could keep the heat range continuous in air-conditioned high-rise complexes such as colleges and hotels, regardless of the seasonal fluctuations of the outdoor temperatures and various heating impacts inside the building.
E-pumps with heat range sensor increase comfort and lower operating costs weighed against pumps without a temps sensor. A regular drinking water level ensures optimum and cost-efficient procedure because of this of a well balanced steam development.
3. 2 Applications of submersible pump
The pumps are suitable for raw water resource, irrigation systems, groundwater decreasing, pressure boosting, fountain applications, mining applications and off-shore applications.
In other countries, submersible pumps provide irrigation and drinking water source systems from the groundwater by submerging in the well.
3. 2. 1 For sea normal water application
Cathodic protection by means of zinc can be used for corrosion security of SP pumps in chloride-containing liquids such as brackish normal water and seawater.
Songs of the sea
Songs of the ocean is a stellar combo of technology, imaging and live personas. Lights, lasers, flames effects and normal water jets create a sensational visual feast together with attractive computer images projected on gigantic water screens.
Submersible pumps are also found in the place of interest such as songs of the sea in Sentosa. Ruthless and quickness are made by the impeller blades in the submersible pumps prior to the water can photograph high up to the sky, thus it helps to create the result in the performance.
3. 3 Applications of Circulator pump
All the UP pumps shown have the common benefits which include low energy used, low noises is produced, and maintenance is free. Low energy is better as compared to higher energy consumption, and high energy will have a tendency to give higher costs. Sound pollution is cut down when low noise is produced and comfort.
Circulator pumps, which were developed especially for solar thermal home heating systems, boast vitality consumption figures that have almost been halved.
It is more being used in circulating hot water around the houses in cold countries where there are four seasons, for instance, Western european residences. Normally, many places in Singapore such as schools, hotels and shopping centres preferred to work with centrifugal pumps for air-conditioning systems. Hence, circulator pump is very rarely seen or found in Singapore.
4. GSI - Local Projects
After understanding all the functions of the 3 major pumps, Grundfos in Singapore (GSI) has adopted several jobs in the local, and let's have a closer look of what GSI has added in Singapore development.

5. Local Case Stories
5. 1 Efficiency in the Hands of the Law
Grundfos has proven itself to be the suitable partner in being energy-efficient and providing spontaneous after sales service for such a exclusive job from the Singapore Supreme Court docket. Grundfos is asked to provide the pumping solution for Air-Conditioning and plumbing which both these 2 services are incredibly important to the easy procedure in Supreme Court. Furthermore, high quality product is demanded for the pumps to perform for extended hours in a day operation. The domestic plumbing and Air-conditioning deals are from Daiden and Symbol Point, who will be the HVAC contractor and plumber respectively. The plumbing related contract contains 4 packages of Grundfos CRN booster systems.
The system that can be used in the water supply and copy pumps is to guarantee the comfort of a continuous supply of a good quality drinking water from taps at a comfortable pressure. The systems not only quench thirst but also provide continuous water source for the flushing systems in toilets and also serve the other needs. 5 sets of Grundfos AP100 sewage pumping systems are being used in sewage ejector systems and drainage system over the structures to keep courts dry and clean. Trustworthiness and low noises made by the pumping systems are of paramount concerns, and systems are also likely to handle all types of solids which are anticipated to be drained in to the systems.
Grundfos offered 27 collections of Grundfos horizontal splitcase pumps to the air-conditioning systems. As these pumps have been picked under strictest criteria of efficiency and noise emission level to operate every hour the courtroom is in operation. Also the compact design of the Grundfos horizontal splitcase pumps gives a more reliable, sturdy procedure and prolonged pump life while creating a lower noises level.
5. 2 Singapore's struggle with SARS --- Grundfos has a component to play
Most Singaporeans have heard of momentary built-in wards in Singapore General Clinic and Tan Tock Seng Medical center. These wards were used to isolate SARS patients from the others of clinic community. Inside the SGH wards, there would be 20 fully fitted-out pots with bathroom and bathtub facilities for patients, providing 40 isolation rooms and another six containers for the staffs. The building tasks at the clinics were granted to 2 companies, particularly Magnificent Seven Structure Pte Ltd. among other essential, they had chosen Grundfos as their only pump distributor for pumping systems necessary for this task.
The pump systems used per location include 2 booster pump systems using CRN 16-40 pumps, together with one 300litre capacity container. Booster systems are essential in this situation as water supply is remote control from the mains. The pumps were decided on for use based on certain requirements of the hospitals and the conditions enforced. Individual flush valve systems were also found in both nursing homes for the sewage and sanitation facilities in the wards. These used 3 CRN 16-40 pumps, supplied with a 300litre tank. The 2 2 hose-reel systems made up of CHI 4-60 pumps. Pressure vessels were included whenever necessary.
6. SWOT analysis
- Energy saving
-There a wide range of purposes of the pumps
-Wide types of pumps to choose
-materials made of high quality metal steel
- Able to select the types of metal steel
-materials used can be recycled helps to save the earth's limited options and energy.
- High price of pumps; might be too expensive to afford, that is because of the material made of (e. g. quality of stainless steel used).
- Can promote circulator pump to cold countries for hot water circulation
- Price balance in other country (moving down of the 'blueprint' for the other country to make; in other words the make and labour cost stay within the country's market price)
-So low labour cost low production cost (e. g. China)
- Others in the same industry (Ebara, Wilo) which they are selling almost the same pumps as Grundfos and makes them as the competitors.
*Ebara is a pump creation company from Japan and Wilo is from Germany.
With more than 73 companies right across all the continents of the world, Grundfos is one of the world's leading pump manufacturers, really helps to supply drinking water using their pumps. Although our Earth has 97% of seawater and 3% of fresh water, two-third of the new water is destined as glaciers and polar ice. The remaining, significantly less than 1% of all water on the globe, is somehow available in different options for mankind to make use of. With this really small amount of fresh water, it is insufficient to supply to the global use. Grundfos would like to take up this opportunity, to utilize their pumps to provide normal water resource system.
Grundfos is constantly striving to make its products more user-friendly, reliable, energy-saving and effective, so that both users - Grundfos and its customers and the environment reap the benefits of their improvements. Grundfos pumps include ultramodern electronics including the built-in pressure sensor, permitting them to regulate their outcome corresponding to current needs. This not only ensures convenience for the user, but also saves a great deal of energy.
As it is mentioned previously, CRN is made of better class of stainless than CRI so the price of the pump is more expensive. The inner area of the pump where it associates with this particular more, will made of higher grade stainless steel to be able to prevent any corrosion. Let's say that if the pump is completely made of high quality stainless steel, then your price will be much higher and cost. This is why why Grundfos pump is very cost, as they aim for the higher quality of pump. Recommending that the customer can choose to acquire outer part of the pump with lower class stainless steel and except the interior part will need to have higher grade stainless. Hence, it can help to save the price and long term of the pumps as well as low production cost. The price of the Grundfos pump is also is determined by the sizes.
Higher energy saving of the pumps can help to stop reduced emission of skin tightening and from the air-conditioning systems to the ozone level. When there is required for higher energy of pump, the materials used could be more expensive to create a higher quality of the product.
People in the global choose Grundfos once and for all services, quality of pumps, reputation and standing of the business. Services like unit installation and restoring of the pumps as well as providing the warranty to get more trust. Also, Grundfos has consultants to guide the customers to find the suitable pumps for his or her applications. Since Grundfos is set up in 1945, the reputation is high as they may have managed to get to the top of society for the several decades. Along the street, Grundfos has gained more trusts from the individuals surrounding the world as their pumps have shown the usefulness.
Back to Grundfos in Singapore (GSI), GSI is the regional syndication centre that distributes pumps to China, Korea, Taiwan, Hong Kong, Malaysia, Indonesia, Thailand and India. Furthermore, GSI is accountable for developing some of Asia's newest marketplaces such as Sri Lanka, Nepal, Philippines, Vietnam, Laos and Cambodia. Generally, centrifugal and submersible pumps are being found in local. For occasions, centrifugal pumps are being used in the HDB to ensure the normal water can reach every floor fast which also offers to control the water pressure. As the submersible pump is considered has the similar function with centrifugal, however the only difference is submersible pump can submerge in the ground for groundwater resource such as irrigation. Not just that, submersible pumps also performed a little role in tourism panel in Singapore. By using it to be an attraction put in place Sentosa, Songs of the sea, to appeal to more visitors, thus it enhances our economies. When choosing the right pump, the affecting factors are the PH value, chloride content, heat and awareness of the pumped water and pressure. If the suitable pump is not chosen, the pumps might rust easily or exploded as the pumped water is very intense. Last but not least, Grundfos in Singapore has triumphed in the projects in local whereby displaying their effective, reliable, energy-efficient alternatives. Eventually, the usefulness of the Grundfos pump has given big contributions and advantages to our day to day life and population.
