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.

  • Some of you may have wondered what the difference is between a 1 stage and 2 stage pump. In this video I go over the difference between the two, hopefully helping you to decide which pump is best for you. Either will do the job. The single stage is a 2.5 CFM pump and the two stage is a 3.9 CFM pump. They are both mid grade, non name brand pumps. I’ve since purchased Robinair pumps and the difference between them and the 2 stage you see here is quite amazing. It is much quieter overall, and much more solid. I will put up a video of it soon.

    I dedicate this video to the troll of the week: KushPlants
    He likes to call me zipperhead and other racial slurs. He even logs into other accounts so he can hate on me from multiple directions lol.

    Frequently Asked Questions:
    Q. How much butane do you use? A. I utilize 1 can of high quality butane per oz of high quality trim/flower.
    Q. What tubes do you use? A. Extraction Experts XL Tubes. Good tubes, company always ships super slow though. I’ll be moving to new tubes soon.
    Q. What kind of filters? I use 100 micron metal screens in conjunction with 25 micron pressing screens, as well as unbleached coffee filters at times although I much prefer pressing screens as they hold up better for longer.
    Q. How long do you vacuum purge for? A. Till I’ve reached the desired honeycomb texture I want, or till I have a clean shatter that will not move under pressure at 110f.
    Q. Do I really need a vacuum pump and chamber for making good oil? A. It is not 100% necessary, but I HIGHLY recommend it for top shelf oil. It will make your job a lot faster and easier, and help to ensure you a safer product.
    Q. What kind of pump do you use? A. Robinair 2 Stage 3 CFM Pumps.
    Q. What kind of butane do you use? A. I mostly use Power 5x, but also like Vector and Colibri (twice the price).
    Q. What kind of vacuum chamber do you use, and where can I buy one? A. Vac-It Pro and you can only purchse them on eBay. They are around $120.
    Q. Do you constantly run the vacuum pump? A. Yes
