Tobee™ Dredging Sand Pump

Tobee™ WN Dredge Pump is horizontal, single-stage cantilevered structure, which is designed to meet the requirement of the contractor demanding and comprehensive dredging requirement. WN type dredge pump impeller passage is very wide, to continuous pumping gravel or high plastic clay and not happens jam. The minimal amount of wear parts design in these dredge pumps results in reduced wear, long life and lower maintenance which translates into less downtime, significant cost savings and dredging good performance within high efficiency.

200 WN - 500 WN type dredge pump integral by a single pump shell, single stage single suction cantilever horizontal structure, press and gear box of the connection way all can provide two kinds of typical structure, namely take bracket type and pump box and type. Own bracket type lubrication way as the grease lubrication or thin oil lubrication.

600 WN - 1000 WN type dredge pump overall adopts double pump shell, single stage single suction cantilever horizontal structure, bring their own bracket, lubrication way as the forced thin oil lubrication. Double pump shell the safety and reliability of the design makes sheath always can use to close to wear through, and when sheath rupture, pump room will not fill.

Detailed specification:

1.Overall construction ship uses in the cabin
With natural good WN Dredge pump are used in submarine to satisfy the different hull structure to the mud sand pump request, the serviceability is broad.
The pump whole use the horizontal-type single stage single suction bracket structure, according to the gear box joint way it may provide two kinds of structure, namely the pump service department dispenses the gear box to gather a form or the pump bringing bracket and the gear box through the junction box connection.
2.Dredging performance finely
Through the optimized design, the WN dredge pump have the good performance, the mud pump attract ability, digs deeply,the density is high, concentration, the WN dredge pump flow channel is worry-free,the overflow performance is good.the Mud pump performance curve drops,has the very good compatibility to the row of distance change.WN dredge pump may through changing the impeller the rotational speed or changes the impeller's the diameter to realize the pump current capacity,head adjustment.
3.Resistancees to wear are fine, the overflow life long
WN Dredge pump wet-end part uses the high strength antifriction metal to cast iron (KmTBCr27), degree of hardness is smaller than 58HRC, has very strong bears the impact ability and good abrasion performance.
4. Efficiency high, the benefit good
WN dredge pump water power design use CFD to carry on the flow field simulation, the mud sand pump efficiency is high, simultaneously avoids in the flow channel the excessively quick change to the overflow partial attrition, reduce the spare parts the consumption,guaranteed the pump the reliable movement,the economic efficiency is remarkabie.
5.Axes seal the form
WN dregde pump to be possible to use the packing seal, the mechanical seal,the skeleton seal (replenishment fat), the wing nut (add L rubber seal) and so on many kinds of seal form,satisfies the customer the demand.

Tobee™ WN Dredge Pump Shaft Seal:

Packing seal:

As one of the most commonly used seals for rotating shafts, the packing seal can come with low-flush or full flush arrangement which uses flushing water to prevent media from escaping the pump housing. This kind of seal is suitable for use under all pumping conditions. In situations where corrosive solids or high temperature might be encountered, Teflon or aramid fiber is used as the packing material for the gland. For high abrasion conditions, a ceramic shaft sleeve is available. 

Expeller seal:

The combination of impeller and expeller creates the pressure needed to seal against leakage. Together with the gland seal or lip seal which is used as the shut-down seal, this type of seal can handle sealing requirements for applications where full-flush gland seal is impractical due to lack of water on the site, or sealing water is allowed to enter inside the pumping chamber to dilute the slurry.

Mechanical seal:

TG Dredge Pump utilizes a leak-proof mechanical seal design which allows easy installation and replacement. Other types of mechanical seal are among options to suit the slurry pump for various pumping applications.
