New technology for SE and SL series Grundfos announces that its SE and SL pumps are available with innovative technologies and functionality ensuring optimised performance.
can be permanently installed using an auto-coupling guide-rail system or with a fixed pipe connection, and are also for freestanding installation or as portable utility pumps
The SE and SL wastewater pumps are designed for the transfer of drainage and surface water, domestic, municipal and industrial wastewater, and process water. They
These heavy duty wastewater pumps, are claimed by Grundfos to offer the best total, wire-towater efficiency yet seen with IE3 motor efficiency and new hydrau-
lics, including the S-tube impeller, with hydraulic efficiency and nonclogging capabilities, without compromising free passage. The SE and SL ranges of submersible and dry-installed wastewater pumps are available up to 30 kW. The SL range is for submerged installation, and the SE range is for all installation types, including

World’s largest hose pump is unveiled The LPP-T100 from Flowrox can pump maximum flow of 100 m³/h with pressure up to 10 bar.
LPP-T100 from Flowrox
Flowrox’s roller design enables the pump to deliver 31 l per single 360° revolution and still only requires 25 l of lubricant. Flowrox hose pumps are developed for pumping various slurries and dosing a wide range of abrasive, corrosive, viscous or crystallizing
media. The hose pumps incorporate a design, which eliminates friction, maximizes hose life time and reduces energy consumption. They offer various process benefits, such:
• Medium does not have to be homogeneous
• Continuous flow rate 24/7 without overheating, resulting in higher flow with a smaller pump.
Flowrox hose pump can operate in hot temperatures and can run continuously even in 98°C degrees due to the low friction rolling design.
• Accurate flow

• No mixing or shearing of the medium
Multiflo highwall offering New AODD version for launches to market chemical delivery Weir Minerals Multiflo (WMM) launched its Multiflo MH-C2 highwall pump. The Multiflo MH-C2 highwall pump is a highwall mine dewatering pump for the mining and resources market. The pump was developed in response to industry feedback following the major flooding disasters of 2011 and 2012, and is expected to contribute to job sustainability, as well as provide other important economic benefits and improved environmental outcomes.
dollars a day in lost productivity, we believe the Multiflo MH-C2 highwall pump will be extremely well received by the industry, simply because of the urgent need for a robust and reliable highwall mine dewatering solution.”
The manufacturing industry was worth (Aus) $590 M to the Sunshine Coast region in 2008, and has become one of the region’s biggest contributors to jobs growth and economic output.
Featuring an environmentally friendly dual pipe system that separates hydraulic oil hoses from the dedicated discharge pipe to reduce the risk of hydraulic oils contaminating discharge water, the Multiflo MH-C2 is a welcome advancement in mine site dewatering technology.
WMM managing director Paul Avey commented, “With a flooded mine or quarry costing up to a million

WMM has previously stated it would like to see a greater emphasis placed on pre-emptive dewatering strategies built into risk management policies for the industry to mitigate loss of jobs, productivity and lives.

Trebor International is introducing a new version of one of its Magnum 620 pumps. The 620D (D for ‘D style’) is the third in a series of pumps offering deadhead capability. The new pump allows fabrication technicians to more efficiently control flow requirements to tools in chemical delivery systems where high back pressure exists, which is commonly referred to as deadhead. The 620D is deadhead capable with a single air supply, allowing the pump to run without power and providing a non-stalling shuttle once a supply valve is turned off. In deadhead situations, one or more valves are turned off to control flow rates at the end use point. In those situations, there is an increase in the backpressure on the pump. Most pumps either completely turn off or continue to
cycle. Neither is a good option. In the case of a complete turn off, supply pressure is lost and the pump cannot immediately respond to the open valve at the necessary pressure for the application. In the case of a continuously running pump, inlet air supply is unnecessarily consumed, which adds costs to the process and there is ongoing wear and tear on the pump. The Magnum 620D directly addresses these issues. When valves in a system are shut off, the 620D responds by pausing operation – the pump shaft pauses causing no additional wear and tear or air consumption. In addition, when the valve is opened, the 620D immediately responds with the necessary supply pressures without priming or air bubbles. www.treborintl.com
