Keystone Pumps

09 Mar.,2023


The company has a group of cooperation teams engaged in the sludge sump pump industry for many years, with dedication, innovation spirit and service awareness, and has established a sound quality control and management system to ensure product quality.

This is one of our Submersible Slurry Pumps model HDS 100L (4″ Discharge) Agitator, operating in the Texas Oil Fields.  Our customer says the pump was unsupervised for over a day and it was still pumping, even with the massive build up of solids.

Our customer was super happy as they have used almost every submersible pump on the market and the Keystone submersible pump is the only pump they have used that can take this kind of abuse over and over again.  Further, Keystone has the run dry mechanical slurry seal and a heavy duty submersible motor to ensure that you can get the maximum life out our your submersible pump.

The following pumps are our customers go to pumps for Drilling Mud Cellar applications:


HDS 100L-A (4″ High Chrome Pump with Agitator/ 15HP, 1800 RPM)

HDS150L-A (6″ High  Chrome Pump with Agitator / 30HP, 1800 RPM)
