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.

    This instructional video will show you how to install or replace a shower pump.
    For the purposes of this video we are installing a Grundfos Niagra 1.5 bar
    shower pump. But this video will work for Salamander, Grundfos Amazon, Grundfos nile and Stuart turner. The 1.5 bar relates to the pressure output delivered by the pump.
    When you receive a pump they often come with flexible hoses supplied. This makes the
    installation much easier. These are rubber washers to use in water connection.
    They’re very important so don’t lose them. If we look closely we can see the
    water supply inlet and the rubber feet. These disperse
    any vibration caused by the pump in operation. On the outlet of the pump there are two
    pressure sensors. When the
    pressure drops due to a shower being opened the sensors activate the pump.
    Before doing any work on a shower pump ensure it is electrically isolated by switching it
    off and pulling the fuse. Remove the electrical box cover and remove the wires
    once you have ensured they are not live by using a volt meter.
    Turn off the hot and cold water supply to the pump.
    Remove the pump water connections, making a note of which ones are the inlet and
    the outlet.
    Sometimes water is still in the pipes so have a bucket or towel handy to catch any drips.
    Remove the old pump.
    Fortunately the new pump is the same model so no major alteration in
    pipework is required.
    Use the rubber washer supplied to make a watertight seal. Ensure the washer with the gauze filter
    is on the inlet. This protects the pump from any debris in the water. Tighten all joints right up and turn on the water supply. Check for leaks.
    Now remove the electrical cover of the new pump. Thread your wire through the nut, rubber washer and cover before connecting the wires. Identify which wires go in which terminal and using a small slotted screwdriver tighten them in place.
    Now replace your electrical cover.
    It’s often a good time to try and purge your system of air before running the pump. Do this by opening your shower valve.Turn on the electrics and test pump operation by using the shower.



    A cutter-suction dredger’s (CSD) suction tube has a cutting mechanism at the suction inlet. The cutting mechanism loosens the bed material and transports it to the suction mouth. The dredged material is usually sucked up by a wear-resistant centrifugal pump and discharged either through a pipe line or to a barge. Cutter-suction dredgers are most often used in geological areas consisting of hard surface materials (for example gravel deposits or surface bedrock) where a standard suction dredger would be ineffective. In recent years, dredgers with more powerful cutters have been built in order to excavate harder rock without the need for blasting.
