Mud Pumps
Triplex pumps that circulate drilling fluid at high pressure.
- Triplex single-acting design
- Interchangeable liner sizes
- Forged fluid end modules
Mud and solids control
Mud Pumps and Solids Control Equipment
Drilling fluid cools the bit, carries cuttings to surface and holds back formation pressure. Keeping it moving and keeping it clean protects the well, the bit and every pump and valve in the circulating system.
Kronborr supplies mud pumps, shale shakers and screens, and hydrocyclone desanders and desilters, together with the expendable parts that keep them running.
The range
Mud and Solids Control: Product Families
Shale Shakers and Screens
The first and most important stage of solids control.
- Linear motion vibration
- Adjustable deck angle while running
- Quick-change screen clamping
Desanders and Desilters
Hydrocyclones that remove fine sand and silt after the shakers.
- Polyurethane hydrocyclone cones
- Manifolded cone arrays sized to flow rate
- Optional underflow screen for fluid recovery
Decanter Centrifuges
High-speed separation of fine solids and barite recovery.
- Variable bowl speed for barite recovery or fines removal
- Wear-resistant scroll and bowl linings
- Variable frequency drive options
Circulating the Fluid
Triplex mud pumps move drilling fluid at high pressure down the string and back up the annulus. Their power, stroke length and liner size set the flow rates and pressures available for hole cleaning and bit hydraulics.
Removing Drilled Solids
Solids control works in stages. Shale shakers remove the coarsest cuttings with vibrating screens; desanders and desilters then use hydrocyclones to remove finer sand and silt. Every stage removes solids the next would struggle with, so the first stage matters most.
How to Size a Solids Control System
Size the system to the maximum circulating rate in your program, the fluid type (water-based or oil-based) and the formations being drilled. The shakers must handle the full flow with the screens you need, and hydrocyclones must process more than the circulating rate.
Send your circulating rates, fluid type and rig layout and we will propose a matched set of equipment.
FAQ
Mud and Solids Control: Common Questions
How often should shale shaker screens be changed?
It depends on the formation, fluid and screen type. Screens should be changed when torn or blinded, and their life can be extended with correct deck angle, feed distribution and washing. See our guide on extending screen life.
What is the difference between a desander and a desilter?
Both use hydrocyclones. Desanders use larger cones to remove sand-sized particles; desilters use smaller cones to remove finer silt-sized particles.
Do you supply mud pump expendables?
Yes. Liners, pistons, valves, seats and seals are in our spare parts range.
