  • WN (WNQ) series mud pump --our company uses the advanced computer-aided design, in view of scours, blows fills in the profession the dredge boat the new mud pump which researches and develops with the pump.


    Features:

    1.Overall construction ship uses in the cabin

    with natural good WN, WNQ are used in submarine to satisfy the different hull structure to the mud 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 (Q) mud pump have the good performance, the mud pump attract ability, digs deeply, the density is high, concentration, the WN (Q) mud 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 (Q) may through changing the impeller the rotational speed or changes the impeller's the diameter to realize the pump current capacityhead adjustment.

    3. Resistances to wear are fine, the overflow life long

    WN series 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

    5.Axes seal the form

    WN (Q) mud pump to be possible to use the packing seal, the mechanical sealthe skeleton seal (replenishment fat), the wing nut (add L rubber seal) and so on many kinds of seal form, satisfies the customer the demand.
