Weir Minerals has launched the new Multiflo® Mudflo™ hydraulic submersible slurry pump, engineering the pump to, it says, tackle abrasive applications and large particle handling.

The Multiflo Mudflo pump features a hydraulically driven wet-end specifically designed to efficiently and safely reprocess and relocate tailings ponds, maintain water retention dams and manage slimes and sludge ponds.

It combines the Warman® MGS pump-end, Multiflo CB32 hydraulic cutters and ESCO® excavation teeth to provide efficient pumping of highly charged and abrasive slurries, the company claims.

Weir Minerals’ Ultrachrome® A05 chrome alloy impeller ensures high wear resistance and the specially engineered suction strainer minimises the risk of clogging by preventing large solids and debris from entering the pump. Drawing on decades of Warman pump design experience, the Multiflo Mudflo pump is capable of pumping between 150 cu.m/h and 1,200 cu.m/h, up to 82 m head.

The Multiflo CB32 hydraulic cutters feature the ESCO Ultralok® tooth system to prevent premature breakage, avoid tooth loss and protect the integral locking system to ensure the continuous operation of the pump, it says.

Engineered by the Weir Minerals dewatering pump experts in Australia, it is available for global customers from July 2021.

Cameron Murphy, Director of Dewatering Weir Minerals APAC, said: “The Multiflo brand is synonymous with high quality and long-lasting equipment. In designing the Mudflo pump, our dewatering experts drew from the very best Multiflo, Warman and ESCO technology and used advanced hydraulics to create an innovative and cost-effective new solution for mine dredging applications.”

The product was developed following close customer collaboration and a mutual commitment to safety and technical excellence, Weir Minerals said.

Geoff Way, Weir Minerals Dewatering Specialist, said: “It is not uncommon for sites to use a combination of pumps, shovels, excavators and trucks for dredging applications. When one of our long-time partners in Indonesia contacted us about developing a custom solution for the slurry build-up in their sumps, we knew we could provide a better solution. We are problem solvers. We considered our customer’s pain points and engineered a new solution to efficiently and safely manage their site processes.”

The Multiflo Mudflo pump can also be retrofitted to competitor OEM equipment, Weir Minerals says, with the quick-hitch plate attachment ensuring convenient installation and removal from hydraulic excavators.

The Multiflo Mudflo pump can be assembled on land, eliminating the safety risks associated with assembling pumps over water. Furthermore, the new hydraulic hose management system reduces the risk of hose entanglement and trip hazards, all the while providing a reliable hose bend radius to ensure smooth oil flow.
