The speed and efficiency of Enerpac ZE split-flow pumps has helped global heavy lift and transport specialist Mammoet to significantly increase its conveyor installation rate at Rio Tinto's materials handling facility at Tom Price in Australia’s rugged North West.
Enerpac has delivered two stage lifting sets both consisting of 4 BLS506 cylinders operated by a ZE split flow pump, which Mammoet used to install 98 conveyor sections as part of Rio Tinto’s Western Turner Syncline Project, at their open pit mine 20 km north-west of Tom Price.
The sets were used to lower conveyors as part of the installation process and expected to lower one per day.
With Enerpac’s system, Mammoet were able to lower four per day, increasing their efficiency fourfold, despite the extreme conditions of the site.
“We expected to be able to lower one section each day, but with Enerpac’s stage lift system, we were able to install four per day, which substantially improved our overall installation time. We ended up installing 98 pieces completely problem free,” Arjan Nagelhout,Operations Supervisor for Mammoet Port Hedland, explained.
Mammoet is the world’s leading heavy lifting and multi-modal transport solutions specialist for the petro-chemical industry, civil engineering projects, the power generation sector, offshore and marine projects.
Enerpac states that is has over a decade of experience with split-flow pumps. Depending on the application, Enerpac has a PP-type split-flow pump as well as its ZE-series with split-flow functionality.
For this project, which is part of a mine that produces 6 million tons of ore a year, Mammoet used the ZE split-flow pumps.
“Each pump out of our ZE-,ZA- or ZG-series can also be delivered with split-flow functionality to meet the exact requirements of any application. The biggest advantage is that it gives accurate control in lifting due to equal flow rates,” Enerpac Integrated Solutions Manager for Australia, Richard Verhoeff, said.
The split-flow pump also has the option of wireless controls for easy and safe operation as the operator does not have to be by the pump to operate it but can freely move around the object being worked on.
The ZE series of 700 bar electric pumps from Enerpac is engineered to save power and increase reliability by reducing the number of moving parts it incorporates, enhancing flow characteristics and reducing friction.
The high-efficiency design of the ZE series electric pump has higher oil flow and by-pass pressure, runs cooler and requires 18 per cent less current draw than comparable pumps, says Enerpac.
The totally enclosed, fan-cooled electric motor supplies extended life and stands up to harsh industrial environments encountered in Australia and New Zealand,including mining, oil and gas, energy, manufacturing and metal fabrication applications.
By reducing the number of moving parts, improving flow dynamics and decreasing friction, Z-Class pumps will stay on the job longer, require less energy to operate and when needed, have lower service costs.
