Product Introduction
WN (Q) dredging pump is a kind of highly effective wear-resistant marine dredging pump, which is based on absorption of abroad technology. WN (Q) dredging pump meets the comprehensive dredging requirement at home and abroad.
Features
Overall structure performance well in marine use
Simple and reliable structure: 200WN-500WN and 600WNQ-1000WNQ type dredge pump with a single pump casing or double pump casing, single stage single suction cantilever horizontal structure. According to the connection type with the gear box, there are two kinds of typical structure, one is with independent support, the other is combined with gear box. The lubrication of pump with support is grease lubrication or thin oil lubrication. The double casing design can make the pump body safe even when the liner is worn out. Easy to disassemble and maintenance: WN type dredging pump can be disassembled from front. This make the disassemble and maintenance easier.
Good performance of dredging
Good cavitation performance: WN type dredging pump have good cavitation performance which can ensure suction ability of pump. While it can achieve greater digging depth and higher suction concentration.
High flow capacity and wide applicability: WN type dredge pump impeller passage is very wide to continuous pumping gravel or high plastic clay and not happens jam. Good carrying ability of pump is guarantee for dredger performance.
Sharp Dropping performance curve: The flow and head curve falling steeply makes the mud pump having a stronger adaptability to the change of row spacing.
Achieving various blendings of pump performance: WN dredging pump can change the rotational speed and the diameter of the impeller, to achieve the different head of pump under the same flow.
Wear-resistant and long-life service wet parts
Wet parts of WN dredging pump , such as impeller, volute liner, throat bushing and frame plate liner insert(wearable liner) adopt alloy cast iron material whose hardness is not less than 58HRC. It has not only impact on resistance but also high anti-abrasion performance.
The service life of each part is fully considered in the process of product design. The same replacement cycle reduces the maintenance and replacement costs.
Small hydraulic loss, high efficiency, low power consumption: Due to the advanced hydraulic model, the dredging pump has high efficiency level. The efficiency of WN dredging pump is higher about 2-3 percentage points than imported. Thus, in the same production, it can achieve lower fuel consumption.
A reliable seal and no leakage
200WN-500WN dredge pump adopts mechanical seals or packing seals or combination of mechanical and packing seals.
600WN(Q)-1000WN(Q) dredge pump adopts shaft seal with L-shaped screw shell rubber seal device which has three L-shaped seal rings and one shaft sleeve with special thread.

The market for flue gas desulfurization systems (FGD) will exceed $6 billion per year over the next decade. However, whether it is just $7 billion or as much as $10 billion depends on regulatory initiatives which are not yet solidified. This is the most recent forecast in the McIlvaine report, FGD World Markets.
Flue gas desulfurization systems remove SO2 from the stack gases of coal-fired power plants. The market is split between older plants which must retrofit FGD and new plants which must include FGD. Presently less than half the world’s FGD capacity at power plants is fitted with FGD systems, so the retrofit market is quite large. In addition many FGD systems in Europe, Japan and the United States are more than 20 years old and must be replaced.

STORYLINE
Workers from the Dutch salvage firm Smit continued their preparations on Sunday as they waited for the green light to remove fuel from the stricken cruise ship, the Costa Concordia.
According to Smit, there are about a half million gallons (2,400 tons) of heavy fuel oil on board the vessel, as well as some 200 tons of diesel oil and smaller amounts of lubricants and other environmentally hazardous materials.
The ship is perched precariously on a rocky ledge of seabed near Giglio island.
There are fears the vessel could tilt further and plunge some 90 feet (30 metres) into deeper water, further complicating the pumping operation and possibly rupture fuel tanks.
Italy’s environment minister has warned that if the tanks break, the thick black fuel would block sunlight vital for marine life in the seabed.
On Saturday, authorities said light fuel, apparently from machinery aboard the capsized ship, was spotted in nearby waters.
Franco Gabrielli, the head of Italy’s civil protection agency, also suggested that the luxury liner would have leaked contaminants on board when it tipped over.
But Coast Guard official Cosimo Nicastro said there was no indication that any of the nearly 500-thousand gallons (2,400 tons) of heavy fuel oil has leaked from the ship’s double-bottomed tanks, seen as a risk if the ship’s position changes.
He said the leaked substance appears to be diesel, which is used to fuel rescue boats and dinghies and as a lubricant for ship machinery.
At least 12 people have died and another 20 are missing following the shipwreck on 13 January.
