Pressure on Concrete Stationary and Boom Pumps

Increased demand of equipment with distinctive features are driving the stationary concrete pumping and concrete boom pumps sector in India.

Partha Pratim Basistha explores the equipment variants being provided by manufacturers to cater project specific requirements and overall emerging market demand.

Contrary to couple of years back, specialization is being characterised in utilization of concrete pumps among contractors both for high end and real estate projects. The distinction is essentially in terms of usage of equipment with enhanced concrete pumping pressure, better reach and rugged features to counter abrasion.

Schwing Stetter
Requirements of equipment with improved reach, supported by increased pumping pressure is mainly on account of bigger size project requirements, not to mention tight completion schedules. In accordance with this, Hindustan Construction Corporation used number of Schwing Stetter stationary concrete pumps to pour concrete to its recently completed landmark, Bandra-Worli Sea Link Project in Mumbai. "Based on pouring concrete at high intensity with greater precision, the contractor used eight numbers of Indian manufactured BP 1800 and Germany imported, BP 3500 stationary concrete pumps with a pumping output of 46 cubic meter/hour-65 cubic meter/hour. Additionally,
Schwing Stetter
21 numbers of Schwing Stetter's, AM 6SHN of transit mixtures were deployed for the completion of India's mega project," says, Mr. V.G. Sakthi Kumar, Chief Operating Officer, Schwing Stetter (India) Private Limited. He adds, "for pumping concrete efficiently, Schwing uses advanced rock valve and flat gate valve technology in its stationary pumps." Schwing Stetter makes pumps available having an output capacity between 46 cubic meter/hour-96 cubic metres per hour.

Greaves Cotton
In demand with bigger size project requirement, prominent concrete equipment manufacturer Greaves Cotton also offers stationary concrete pumps of higher capacity. As per Mr. K. Sunil Kumar, head Construction Equipments Division, Greaves Cotton "Greaves offers stationary concrete pumps having concrete output of 90, 60, and 46 cubic meter/hour. The equipment can undertake vertical pumping upto a distance of 120 meters and horizontal pumping upto a distance of 430 meter. The equipment has centralized grease pump for automatic lubrication of moving parts."

While Greaves truck mounted GCP 350 DRT metro pump is capable of delivering concrete output of 46 cubic meter/hour, comes with a compact design with less overall length and neat storage of end hose and foldable side door, "essential" to work in crammed project sites added Mr. Kumar.

Driven by Application

While emerging bigger size project requirements is essentially driving the concrete stationary pumps and boom pumps sector. It is also the heterogeneous construction application requirements that is driving the sector as well. "Though demand of equipment with increased pressure for higher output, meant for bigger projects continues to characterize the market demand,
there are also demand of mid size equipment as well based on assorted nature of projects requirements," according to Mr. Brahmanand Pandey, Chief Marketing Officer, Sany Heavy Industry India Private Limited. The Chinese construction equipment manufacturing major's concrete stationary and truck mounted boom pumps have been used in India's major infrastructure projects comprising, Delhi Metro Railway Corporation, Commonwealth Games village in New Delhi, irrigation and dam projects etc.

Equipped with S-valve concrete pumping technology, Sany offers its HBT-60 C1413, HBT-60 C 1816 stationary concrete pumps bearing a concrete output of 60 cubic meter/hour. It also offers its HBT-40 C 1410 D concrete pumps having a concrete output of 40 cubic meter/hour apart from having 80 cubic meter/ per hour stationary concrete pumps for the Indian construction equipment market.

As per Mr. Pandey, "having being placed with advanced wearable S-Valve technology, the seal structure in our stationary concrete pumps can automatically make up abrasion clearance, with favourable seal performance. It is made up by pile welding. The axle head made of high–strength alloy steel is processed through nitration, thus being prevented from cratting." He adds, "the new wearable concrete piston in our stationary pumps is developed after study, selection and repeated tests on hundreds of prescriptions. The distinction between a traditional concrete piston and ours lies in the fact that it is made of wearable polyester reinforced urethane material to have a longer service life."

Sany which makes available concrete placing booms having a reach of 32 & 38 meter height would be launching its new mobile concrete pump. The new pump, according to Mr. Pandey, "would be developed exclusively for the Indian construction sector with necessary technological inputs. The equipment would have a concrete output of 40 cubic meter/hour mounted on an Indian truck chassis.

Assorted offering of concrete pumps is also provided by Zoomlion Heavy Industry Science & Technology Development Co. Ltd. Relatively new entrant into Indian construction equipment market, the construction equipment manufacturing conglomerate's concrete pumps have found their usage in projects. According to Mr. Jimmy Pan, the G.M. of Zoomlion Concrete Machinery Division Overseas Business Unit, "more than 60 sets of Zoomlion Trailer Pumps are working in projects, such as L&T Delhi Metro project, Ahluwalia Contracts in Mumbai, JMD Limited in Gurgaon. Two sets of Zoomlion truck-pumps were used by 23YE Construction Group Co. Ltd, a Chinese contractor involved in major construction projects in Jharkhand, Bokaro, Kolkata." Mr. Pan adds, "This year, Zoomlion also successfully recommended a package solution of Concrete Machineries to M/s Simplex for their Libya project."

Zoomlion Trailer Pumps
Mr. Pan says, "We can offer array of concrete pumping equipment to suit different applications." He elaborates, "We can offer a wide variety of Trailer Concrete Pump with the capacity from 40 cubic meter/hour to 125 cubic meter/hour with famous brand engines, such as Volvo, Cummins, DEUTZ, Kirloskar engines. For Indian market, we have designed HBT40RS, HBT60RS (40&60 cubic meter/ per hour) S-Valve equipped trailer concrete pump fitted with local Kirloskar engine, and Japanese hydraulic circuits. The trailer pumps have PLC to reduce the amount of electric components, making in turn the machinery more intelligent."

He informs, "For truck-mounted concrete pump, Zoomlion can supply different model truck pump which ranges from 22 meter to 60 meter matched with the world famous chassis such as BENZ, VOLVO, ISUZU, DAF, MARK, and so on. Moreover, the steel of our truck pump are imported from Sweden, Japan, Australia and USA, clubbed together with our professional manufacturing technique making them technologically refined products. However, for Indian market, we have specially designed 22 meter and 37 meter truck-pump with Ashok Leyland chassis which is more practical and economical."

Zoomlion makes available full range of Concrete Machinery, under its brand comprising trailer Concrete pumps, truck-mounted Concrete pumps, truck-mounted Line Pumps, concrete mixing plant and transit mixers. It set a global record by pumping C100 HPC (High Performance Concrete) concrete to the height of 434 meter in Guangzhou West Tower project in China.

Aquarius Engineer
At par with other manufacturers, home based Aquarius Engineers Private Limited has deployed its stationary concrete equipment and boom pumps in prominent projects across the country. This includes, Delhi Metro, Penna Cement in Andhra Pradesh, ROB project at Jharkhand, etc. Aquarius has so far produced and delivered 800 numbers of concrete equipment. As per Mr. Abhijeet Sonawane, Manager Technical & Product Support, Aquarius Engineers, "our boom pumps are highly efficient owing to its significant features primarily owing to its low Diesel Fuel consumption, low wear and tear parts. Additionally, the delivery pipeline is well designed for smooth concrete discharge from the end hose. While proportional servo control valve used for boom movement making the boom pump flexible and precise for proportional distribution of concrete."

He adds, "a boom pump can be powered by either the truck engine (Propeller shaft is cut and separate Splitter Gear Box is used for directing the truck engine power to either truck movement or Boom Pump operations) or by a separate engine.

Aquarius offers the second option i.e. a separate engine is used for driving the concrete pump & boom functions; truck is used only for transportation. Thus the engine can be used very effectively & economically as there are no power transmission losses."

Concrete Pumping System
On technology employed in the concrete pumps to pump concrete at high pressure and also to ensure safety. Mr. Sonawane informs, "we use Servo Valves for boom operations and slewing, pilot operated check valves for outrigger system (important from safety point of view) and Flow Pressure & Power Regulations control in Concrete Pumping System.

The concrete pumping system and technology we are adopting is state-of-the-art. This additionally is suited for the local site conditions in India. As long as the concrete is homogeneous, non-segregated and pumpable Aquarius pumps are capable to pump the so called ultra strength concrete."

Aquarius have 32 meter and 36 meter vertical reach boom pumps in its product range. It recently delivered Stationary Placing Booms – Hydro-Mechanical type of size 10 and 12 meter placement radius. The company would be launching fully hydraulic operated stationary concrete placing boom of size 17-meter horizontal radius.

In line pumps, Aquarius Fuel Economical series for the normal applications of 12 to 20 floors pumping heights. It has recently launched another model of line pump for RMC applications. This pump will have enhanced ease of handling due to lesser overall length; but at the same time other features of bigger cylinder diameter, sufficient engine power and concrete pressure are maintained intact in this new model.

As per Mr. Sonawane, "an output of 70 cubic meter/ hour is sufficiently higher for most of the projects in India. If pumps of higher output are used, it also causes higher wear & tear of wear parts and delivery pipeline due to higher velocity of concrete. Aquarius offers both the options of output 70 cubic meter/ hour and more also."

Revathi Equipment
Wide range of equipment for varied concrete output requirement is offered by Revathi Equipment Limited. The Chennai based company offers its Revathi Waitzinger stationary concrete pumps manufactured in technical collaboration with Waitzinger of Germany bearing concrete output at 46,55, and 66 cubic meter/hour through its three models THP 45D, THP 50D, THP 60 D respectively.

Ltd has its corporate office located at New Delhi and has its production units at Ludhiana.

This is ably being supported with a dedicated team of Sales and Service team with its offices in New Delhi, Bangalore, Hyderabad, Mumbai, Ludhiana and Kolkata.

It is quite commendable to note that there are good deal of concrete pumping and placing equipment available to contractors to suit varied requirements as mechanization sets in an increasing order. Before acquiring the equipment contractors can make a checklist for selecting the right equipment weighing the pros and cons of its features. However, it is perceived among the features most essential would be taking into account the valve technology employed before buying the right nature of equipment. For knowledge sake it should be mentioned that in rock valve and s-valve the wear and tear part is low. However, the concrete requires to be disciplined before pouring it into the pump. But flat gate valve equipped machines can take upon any nature of concrete. Deliberations on other features could be a part of standard exercise it is felt.
