Asia-Pacific
volute pumps market is anticipated
to grow at a steady pace during the forecast period. A
volute pump is a spiral pump casing often used in centrifugal pumps. The
purpose of the volute is to convert the velocity of the liquid into pressure as
the impeller ejects it from the case nozzle. This is achieved by gradually
increasing the vortex cross-sectional area, fluid flow area, and fluid static
pressure.
As
the centrifugal pump impeller rotates, it increases the velocity of the liquid
in the pump casing. Because this impeller is eccentric to the volute, the flow
area within the pump casing is different and gradually increases. Fluid flow
due to impeller action begins at the part of the scroll closest to the impeller
with the smallest cross-sectional area. As the fluid moves around the casing to
the exit area, it builds up pressure as it fills the enlarged area of ​​the
vortex. Therefore, the fluid gains maximum pressure at the exit region where
the swirl area is the largest.
From
a techno-economic point of view, volute pumps are the best pump option for
handling large volumes of water. Volute pumps ensure strength and rigidity and
virtually eliminate corrosion and erosion problems. Volute pump housing and
suction pipes are made of in situ concrete with rotating metal parts. A volute
pump consists of three main sections: a concrete volute and draft tube, a cast
embedded component, and a rotating assembly. These pumps are useful for
applications that need to handle high flow rates and are ideal for seawater
applications. Advantages of centrifugal pumps include high reliability, simple
construction, excellent operating performance, vibration-free equipment, and low
maintenance costs.
Oil
& Gas Industry is Expected to Propel the Asia-Pacific Volute Pumps Market
Asia
poses the greatest threat to global net-zero targets due to a single factor:
the dominance of fossil fuel energy. The Asian oil and gas industry is a key
factor in addressing CO2 emissions. Over the last 40 years, Asia has
experienced a significant increase in oil and gas consumption. It accounts for
a large part of the overall energy mix and energy supply. Nevertheless, oil and
gas are still small in the Asian power mix compared to the rest of the world.
The region offsets this with coal, which accounts for more than half of its
power generation. Asia lags behind the rest of the world in phasing out fossil
fuels. However, this does not diminish the importance of continents in the
energy transition. On the contrary, according to the International Energy
Agency (IEA), the projected increase in energy demand in Asia over the next 20
years will be a major driver and proxy for global energy trends. In 2018,
according to International Association of Oil & Gas Producers, China was by
far the largest oil producer in the Asia-Pacific region. Their production was 3.8
million barrels per day, making China accountable for 49% of the region's total
production. The other largest producers were Indonesia with 12% share, India
with 11% share, and Malaysia with 9% share. Asia-Pacific consumes 35% of the
world's oil and processes 34.6 million barrels per day. This consumption has
increased by a third over the past ten years. China was the largest consumer in
the region. Demand in excess of 13 million barrels per day accounts for 38% of
total Asia-Pacific demand. India was the second-largest consumer in the region,
with rising wealth and industrialization accounting for 14% of total oil demand
in the Asia-Pacific region. Japan was the third largest consumer in the region,
accounting for 12%, while South Korea accounted for 8% of the region's total
oil consumption. With the exception of Japan, demand across Asia Pacific was at
or above record levels in 2017. This demand is expected to drive the growth of
the Asia-Pacific volute pumps market during the forecast period.
Recent
Developments propelling the Asia-Pacific Volute Pumps Market
Water
and wastewater treatment is necessary to meet the demand for water resources.
It is essential not only for municipal and agricultural purposes, but also for
industrial processes. Wastewater treatment is becoming a priority in many
countries and regions around the world. The water and wastewater treatment industry
in Southeast Asia is in a growing stage, and countries in the region are at
different stages of development. The scale of water and wastewater-related
problems is enormous, impacting human health, coastal and terrestrial
ecosystems, and climate change. These problems require the introduction of
water treatment processes to overcome the problems associated with wastewater
treatment. Infrastructure in Southeast Asia looks at some of the initiatives
countries are taking. The Cambodian government also plans to build a second
small-scale waste treatment plant in 2025, and the Asian Development Bank has
signed a USD332.05 million loan package with the Ministry of Economy and
Finance, helping Cambodia recover from the effects of the COVID-19 pandemic.
This includes USD30 million for the Greater Mekong Subregion Health Security
Project, USD180 million for the Liveable Cities Investment Project, USD82.05
million for the Road Network Improvement Project (Phase 2), and USD40 million
for the Comprehensive Financial Sector Development Programme. The Liveable
Cities Investment Project will help provide better sanitation and waste
management services to more than 140,000 residents of the cities of Bavet,
Kampot, and Poipet. The funds will also help improve the city's stormwater and
drainage systems and reduce flooding. Vietnam's rapid growth and
industrialization have a negative impact on the country's environment and
natural resources. According to the World Bank's water report, water
productivity is low at around 12% of the global benchmark, and domestic water
demand continues to grow. Currently, Vietnam's water supply covers only about
70% of its demand, and the water loss rate is relatively high at about 30%. The
country has several centralized wastewater treatment plants and about three
quarters of industrial wastewater is discharged into the environment without
proper treatment. Vietnam's largest project, the Soc Son Waste Power Generation
Project at Hanoi's Nam Son Waste Treatment Complex, began operations in August
2021.
The project consists of a wastewater treatment plant designed to treat
1,740 tons of wastewater per day. It also has the capacity to process 4,000
tons of solid waste. The project required him to invest USD303 million.
Singapore used to rely on imports from Johor and Malaysia for its water supply.
Singapore has built a robust, diverse, and sustainable water supply from four
sources, known as the Four National Taps. These four water sources include
water from local catchments, imported water, high-quality treated water known
as NEWater, and demineralized water. The NEWater process recycles treated used
water into ultra-pure, high-quality treated water. There are currently five
NEWater systems in operation in Singapore. Other countries such as India have
also adopted his NEWater process in Singapore to improve domestic raw water
supplies using highly treated wastewater. Many countries in Southeast Asia are
facing severe water shortages. The increased demand for clean water, increased
water pollution, stringent government regulations on water treatment, and
increased discharge of industrial waste into water bodies require initiatives
to expand wastewater treatment plants in these countries.
