MAX2000® Mud Guns
Effective Mixing and Suspension
The MAX2000® Mud Guns for submerged service are highly effective in producing currents that efficiently mix and suspend particles, thus reducing the buildup of solids in tank corners.
Rugged Construction
Constructed of rugged materials, the 3″ low-pressure guns are designed to resist wear and corrosion, ensuring long life even in harsh conditions.
Versatile Applications
The 3″ unit is specifically intended for high volume applications, such as mud mixing systems utilizing centrifugal pumps.
Convenient Handling
All MAX2000® Mud Guns come equipped with handles, facilitating easier rotation of the unit on its integrated 360° swivel joint, enhancing maneuverability and usability.
FEATURES
- For reducing the amount of solid buildup in tank corners, MAX2000® Mud Guns are highly effective.
- Mud Guns also produce flow currents, which boost fluid movements and aid in the suspension or mixing of particles. In addition, Mud Guns can create an alternate product flow when used in conjunction with agitators.
MAX2000® Mud Agitators
The MAX2000® Agitator offers rugged reliability and design flexibility, featuring efficient helical bevel gearing and a unique lower bearing for easy maintenance. Available in various configurations, it boasts the industry’s strongest shaft coupler and offers a choice of carbon or stainless steel impellers.
MAX2000® Mud Guns
The MAX2000® Mud Guns efficiently mix and suspend particles in submerged service, preventing solids buildup in tank corners. Made of durable materials, they are designed for high-volume applications and feature a 360° swivel joint with handles for easy rotation.
Screw Conveyors
Screw conveyors are an age-old, cost-effective method for transporting semi-solid materials like drill cuttings. The PSI conveyor system uses stock components customizable to specific needs, featuring rugged motors, heavy-duty troughs, and various options like speed control and safety features.
High Shear Hoppers
The shear hopper efficiently diffuses additives into materials using high velocity and turbulence, requiring fewer polymers and reducing bentonite usage by up to 50%. The PSI shear mixer acts as both a radial premixer, preventing clumping, and a mixing eductor, ensuring vigorous mixing and robust shearing.
Mud Gun Applications
PSI’s MAX2000® Mud Guns are built for the full range of drilling fluid handling equipment applications, from active drilling rigs to mining slurry ponds and wastewater treatment tanks.
Oil & Gas Drilling: Mud Tank Agitation & Solids Control
On active drilling rigs, mud guns are installed low in the mud tank to fire high-velocity streams across the tank floor, breaking up settled solids and keeping barite, drill cuttings, and weighting material suspended in the active system. Used alongside PSI mud agitators, mud guns eliminate the dead zones that mechanical agitation alone can miss — particularly in tank corners and along baffle walls. As a drilling mud gun supplier serving Permian Basin, Eagle Ford, and Gulf Coast operators, PSI ships 3″ low-pressure mud guns configured to run directly off existing rig centrifugal pump discharge, with no additional power unit required.
Oilfield Services & Rig Contractors: Fast-Turnaround Mud Gun Parts
Rig contractors running multiple active systems need mud gun systems that can be serviced in the field without pulling the entire unit. PSI’s swivel assembly, nozzle, and handle components are field-replaceable, and as an oilfield equipment manufacturer based in Houston, TX, PSI ships replacement mud gun parts same-day on in-stock items to keep rig downtime to a minimum.
Mining & Slurry Operations: Tank Mixing for Abrasive Fluids
Mining and mineral processing operations use mud guns to keep abrasive slurries and tailings in suspension in surge tanks and process ponds, preventing the settling that leads to costly tank cleanout. PSI’s mud guns are constructed of rugged, corrosion- and wear-resistant materials built to hold up in continuous abrasive slurry service — making PSI a trusted solids control equipment supplier for mining fluid handling.
Water & Wastewater Treatment: Sludge & Solids Suspension
Municipal and industrial water treatment operators use mud guns to prevent sludge and solids from settling and compacting in holding and equalization tanks, reducing the need for manual or mechanical tank cleaning. PSI’s industrial material handling equipment is engineered for continuous-duty tank mixing across water treatment, wastewater, and environmental remediation applications.
Mud Gun vs. Mud Agitator: What's the Difference?
A mud gun and a mud agitator both keep drilling fluid or slurry from settling in a tank, but they work differently and are typically used together, not as substitutes for one another.
| Feature | MAX2000® Mud Gun | MAX2000® Mud Agitator |
| How it works | Fires a directed high-velocity jet of fluid, powered off a centrifugal pump discharge | Uses a motor-driven impeller mounted through the tank wall or top to continuously stir the tank |
| Best for | Reaching corners, dead spots, and baffle areas a fixed agitator can’t cover | Continuous, whole-tank mixing and suspension |
| Power source | No dedicated motor — runs off existing pump discharge | Dedicated electric motor with gearbox |
| Typical use | Installed low in the tank, aimed at corners and along the tank floor | Mounted through the tank sidewall, positioned for full-tank circulation |
| Do you need both? | PSI’s recommended configuration pairs mud guns in the tank corners with an agitator in the tank center for complete coverage — but mud guns can also serve as either supplemental mixing alongside an agitator or as the primary mixing method on their own. | |

How to Size and Place Mud Guns in Your Tank
What’s the recommended tank configuration? PSI recommends installing mud guns in the tank corners, with an agitator placed in the tank center — this combination keeps solids from settling anywhere in the tank. Mud guns can serve as either supplemental mixing alongside an agitator or as the primary mixing method on their own.
Where should mud guns be mounted? Mud guns are installed at the tank floor and angled so the discharge stream sweeps across the corners — the dead zones a center-mounted agitator can’t fully reach. The patented 360° swivel joint and horizontal/vertical handles allow wide-angle adjustment directly from the tank floor, so the gun can be re-aimed in the field as conditions change.
What connection type do I need? MAX2000® Mud Guns are available with flanged or threaded connections to match your existing tank piping, and are custom built to any tank depth.
What pump powers a mud gun? PSI’s 3″ low-pressure mud guns are rated for 75 ft of head at 100 GPM and run off the discharge of a centrifugal pump already in service on the mud mixing system — see MAKDADDY® centrifugal pumps for compatible units.

FAQs
What's the difference between a mud gun and a mud agitator?
A mud gun fires a directed jet of fluid off a centrifugal pump to sweep corners and dead spots in a tank, while a mud agitator uses a motor-driven impeller for continuous whole-tank mixing. Most active drilling fluid systems run both together for complete solids suspension.
How many mud guns do I need for my mud tank?
Most tank compartments use two to four mud guns positioned low along the tank floor and aimed at the corners. Compartment size and baffle layout determine the exact count — contact PSI for a tank-specific recommendation.
What pump do I need to run a MAX2000® Mud Gun?
PSI's 3″ low-pressure mud guns are designed for high-volume mud mixing systems and run off the discharge of an existing centrifugal pump, such as PSI's MAKDADDY® centrifugal pumps — no separate motor is required.
Can mud guns be used without an agitator?
Yes. MAX2000® Mud Guns can provide either supplemental or primary mixing. PSI's recommended configuration is mud guns in the tank corners with an agitator in the tank center, but mud guns alone can serve as the primary mixing method where an agitator isn't installed.
What is the flow rate and head of a MAX2000® Mud Gun?
The MAX2000® Mud Gun is rated for 75 feet of head at 100 GPM for optimal mixing performance.
What connections do MAX2000® Mud Guns use?
MAX2000® Mud Guns are available with flanged or threaded connections, and are custom built for any tank depth. Stabilizers are also offered for secure installation.
