Schwing Stetter, with the use of the SCHWING Concrete Pump SP3000, created history in pumping eight lakh m³ concrete for the 300m high Supernova Spira project, being constructed by Arabian Construction Company at Supertech Supernova site in Noida.

Being built for their high profile clientele who desire a luxurious lifestyle, Spira is an iconic tower located at Supertech Supernova site in Noida Sector 94. It is being constructed by Arabian Construction Company (ACC) and is India’s tallest mixed-use development consisting of 80 floors, standing 300 metres tall.

The building comprises all modern facilities, such as a clubhouse, jogging track, swimming pool and much more. Supertech Supernova is offering the mixed use development and residential, service apartments, hotels, shopping malls, office spaces and recreational centres. ACC has completed the vertical pumping of 200 metres of the iconic tower, Spira, by using the SCHWING SP3000 pump.

Supernova is the biggest mixed-use development in the whole of North India, spread across 5.0 million sq.ft area. It has first-of-its-kind water front development on the banks of the river Yamuna. This entire project costs $30-bn whereas, Spira alone costs $8-bn.


SCHWING Stetter pumps at its best
SCHWING portable concrete pumps are successfully deployed worldwide, whenever vast quantities of concrete have to be pumped over exceptionally long horizontal and vertical distances. In building and civil engineering projects, they are also fast, reliable and economically efficient in handling concrete under extreme conditions concerning concrete design, job site and climate.

SCHWING pump SP3000 has pumped 357,000m³ of concrete. Concrete grade used are M50, M70 and M80, which were pumped at the height of 200 meters.
SP 3000 pump is equipped with variable flow hydraulic pumps that eliminate the risks of overloading the motor. The variable hydraulic flow optimizes the distribution of the oil volume and pressure of concrete pump and automatically adapts to different pumping requirements or pumping difficulties.

The twin hydraulic circuit and soft switching system combined with the open command block ‘hi–flow’, means low heating of hydraulic oil with almost no loss of power, and conservation of hydraulic components.

Materials Used	M80 Core wall Kgs/m3
Cement	440
PPC	120
Micro Silica	30
Water	165
F.A.1 (river sand)	877
20 mm	348

Grade concrete of M80 was pumped at the height of 200 meters, which was quite a challenging task for the team with pumping cylinder with the diameter of 180mm and stroke length 1,600mm. This is a record breaking pumping in high rise construction with M80 concrete grade. The concrete used for the project was primarily M80 (80mpa) grade, whereas M50 grade concrete was the requirement for raft foundation of the Spira tower.

Pipe line layout
The concrete pump was placed in the ground level and the pipeline was anchored inside the tower with 75 numbers of pipes with the height of 200m. The concrete from batching plant (M 1.25 T) was transported using four numbers of transit mixers (AM6SHN) and then fed into the concrete pump (SP 3000) for pumping. For the efficient work progress, the clean system components was kept organized near the concrete pump.

Customer Talk
Sandeep Mazumdar, Project Manager, Arabian Construction Company Limited says, “SCHWING Stetter have helped in training our teams to achieve maximum results. Employing Schwing Stetter equipment has saved the company valuable capital cost, time and workforce, thus adding to our profitability.”
Mazumdar also added that the technical support extended by SSI for this unique and challenging project was tremendous. “We chose SCHWING Stetter because of their remarkable reputation in the industry,” he adds.
Sharat Chandra, DGM, SuperTech India Limited says that they felt that this project was challenging; so, they were looking for a concrete partner who should be committed and can perform as per their expectations. “We handed over this challenging task to SCHWING Stetter India and associated them with this prestigious project. As on date, we are pumping 180m, that too grade like M80 and M70, and their pump SP3000 is performing well,” he says.
