Submersible slurry pump applications

Mud and slurries containing hard solids not larger than 3 mm (1/8”) are frequently pumped by a slurry pump. The slurry pump divided into horizontal and vertical type. Usually, we take vertical type used in HDD mud system

Slurry pump typical applications include:

  • Bentonite slurry walls
  • Drilling fluids
  • Cement
  • Slurries for Ceramics
  • Epoxy, glue, paste and adhesives.
  • Gels

Submersible slurry pump models

Commonly, there will be 50YZ50-20, 80YZ40-10, 80YZ50-10, 80YZ50-20. 80YZ50-20B, 100YZ100-30, 100YZ160-38B, 150YZ250-40B, 150YZ250-40A. The different models indicate different treating capacity and discharges.

The treating capacity from 40m³/h to 270 m³/h. The under water length if no special requirements it will be 1.3~1.5m. According to pumped medium and the mud resource there will be various lift, efficiency, speed, motor power, etc. issues on certain submersible slurry pump.

HDD Mud System

HDD Mud System

In HDD mud system, there will be mud pit or mud pool 10m~30m away from the drilling hole. The mud pit used to containing mud for HDD. 

The mud pit holds sufficient drilling mud when driller begin drilling, we need submersible slurry pump feed mud to shale shaker   

After processed by shale shaker,  the mud will be pumped to desander by another centrifugal pump. And then processed by desilter. When desilter finishes the mud processing the mud will be pumped to clean compartment for another recycling system for HDD continuous operation.

Different HDD hold different treating capacity and requirements on submersible slurry pump. Usually there will be followings to be contained. Such as, 80YZ50-10, its capacity is 50~60m³/h as feeding pump for 100t HDD holds 200GPM mud system. Then 100YZ100-30 for 200t, 300t, 450t HDD system. Of course, depends on various HDD the submersible slurry pump will require different power to match treating capacity demand.

Successful Submersible slurry pump matching with HDD mud system  

GN has designed many drilling mud system. In Horizontal Directional Drilling mud system, we always provided complete proposal with submersible slurry pump. Just few days ago, we configured one 400GPM HDD mud system for Australian HDD contractor. This mud system is with 100YZ100-30 slurry pump holds 22kw motor.

Moreover, there is also 2 HDD mud systems for Korean. This client also needs the submersible slurry pump. Since its treating capacity is 200GPM, the slurry pump is changed to be Vertical centrifugal pump SB4x3-12. It holds treating capacity as 60 m³/h. Same with 80YZ50-10 submersible slurry pump. Choose vertical centrifugal pump because of easy transportation and more convenience.

    I saw a dvd movie relevant to that theme years ago. At this moment i actually accidentally discovered your own post, and it definitely remind me again. Have you got an idea exactly how had been that known as? With Cathrin de Neueu i guess. I will try and google it currently, yet anyway, awesome posting, i love that point of view of you actually. Most definitely i’ll save your site, and maybe look at it again seriously afterward, need to head to job right now.

    Hi there, i read your blog occasionally and i own a similar one and i was just wondering if you get a lot of spam feedback? If so how do you stop it, any plugin or anything you can suggest? I get so much lately it’s driving me crazy so any help is very much appreciated.
