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
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.
Size (discharge): 8" to 40" Pump
Capacity: 600~ 25000 m3/hr
Head: 20m ~ 86 m
Handing solids: 0 ~ 350mm
Concentration: 0%~ 70%

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
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:
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.
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
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
