Multiflo® Mudflo™ pump solution

Our Multiflo® Mudflo™ pump solution has been proving itself in the field since July 2021. Inspired by the Warman® range of gravel pumps, the Multiflo® Mudflo™ pump is designed to provide continuous pumping of highly abrasive slurries, often containing large particles, whilst continuing to maintain high efficiencies.

The Multiflo® Mudflo™ pump is suitable for multiple dredging applications including;

  • mud and sludge management,
  • tailings storage facility management,
  • harbour and marine maintenance,
  • sand and gravel mining,
  • maintenance of water storage capacity in retention ponds,
  • slimes removal from sludge ponds, and
  • land reclamation

The Challenge

Mud, sludge and spoils often accumulate in active or decommissioned mining and run-off pits and at times it is necessary to transfer the material to another, more suitable, location.

It is common practice for sites to use a ‘truck and shovel’ method to transfer mud from sediment ponds and haul it as a part of their ongoing pond maintenance programs. The ‘truck and shovel’ method requires at least a spotter, an excavator operator and potentially multiple truck operators, coupled with a large multi-million dollar budget in associated machinery and operational fuel costs.

This “conventional” process is costly, labor-intensive, time-consuming and has a considerably high carbon footprint. In some instances, it is also a safety hazard to transport mud through a site in a truck bed.

The Solution

  • With over 45 years of experience in floating pump solutions, Weir Minerals Multiflo pump engineers created a new dredging solution for mud, sludge and spoils, the Multiflo® Mudflo™ pump.
  • The Multiflo® Mudflo™ pump combines the Warman® MGS pump-end, Multiflo® CB3 hydraulic cutters and ESCO® excavation teeth to provide long wear life and efficient pumping of highly charged and abrasive slurries.
  • The Multiflo® Mudflo™ pump uses built-in agitators to aid in processing slurries with heavier solids (up to 1.45SG)
  • The Multiflo® Mudflo™ pump can be supplied as part of a complete dredging pontoon barge solution, with Linatex®; hose pipework, and Multiflo® booster pumps OR mounted onto common earth moving equipment such as excavators.
  • The Multiflo® Mudflo™ dredge solution can be dragged or pushed into position and shore-launched using common earth-moving equipment found on site.

Dredge-mounted Multiflo® MudfloTM pump reduces mud processing time by 60%

PT Putra Perkasa Abadi (PPA), located in South Kalimantan, Indonesia, is a full-service coal mining contractor that specialises in overburden removal and run-of-mine coal hauling. At the PT Borneo Indobara (BIB) mine site, the PPA team estimated that there was over 25,000m3 of mud contained within sedimentation dams.

PA needed to find an alternative solution to using extensive machines such as several 30-tonne excavators and multiple Articulated Dump Trucks (ADT) to remove the mud.

The Weir Minerals team designed, fabricated, assembled, installed, and commissioned an ‘Engineered-To-Order’ Multiflo® Mudflo™ 200 hydraulic submersible slurry pump mounted to a dredge. To complete the mud transportation pipeline on site, the team also installed multiple Multiflo® diesel-driven slurry booster pump units.

Reported savings operating at 400m3h at an average of 20 hours per day:

  1. Almost 40% reduction in mud processing costs
  2. 60% reduction in mud processing time

Promoting sustainable solutions


Weir Minerals dewatering experts work together with customers to develop more sustainable solutions on site.
  • The Multiflo® Mudflo™ pump demonstrates efficiency improvements on the current market competitor products (up to 15%).
  • The solution is one piece of equipment that can be operated by a single operator rather than multiple machines with multiple operators compared with the “conventional” ‘truck and shovel’ method.
  • The Multiflo® Mudflo™ pump solution reduces fuel consumption and carbon footprint.
  • The Multiflo® Mudflo™ demonstrates component wear life improvements resulting in fewer replacement parts and therefore limiting machinery downtime.
  • With the Multiflo® Mudflo™ pump solution, the relocation of all pumped material remains fully is contained within transfer pipeline ensuring surrounding environment remains clean and contaminant free.
