6x5x11 Sandmaster Centrifugal Pump

Sandman^® Mission Sandmaster 6x5x11 drilling pump is one of the most trusted pump on the market, when drilling rigs, cementing units, or mobile service equipment need serious pumping capacity but don't have the space to spare. Built on the same proven engineering lineage as the Mission Magnum I series, the Sandmaster pump line trades a bit of footprint for the same rugged reliability, that's making it the go-to choice for tight skids, compact trailers, and space-limited rig platforms.

At first glance, the Sandmaster pump looks a lot like its sibling, the Magnum I. That's by design, the two share nearly identical internals, materials, and performance philosophy. The key difference is size: the Sandmaster's frame and shaft are shortened by about four inches compared to the Magnum, cutting down the overall length of the pump without sacrificing power or durability. That makes it the natural pick whenever mounting space is limited or the prime mover options on a given skid are constrained.

Despite the smaller footprint, the Sandmaster doesn't cut corners on construction. It's built around a heavy-duty frame, a full open-vane impeller, and a one-piece concentric casing that's noticeably thicker than what you'd find on a conventional pump, and all engineered specifically to survive the abrasive, high-solids fluids common in drilling and industrial slurry work.

Design Features

Compact Heavy-Duty Frame Designed for installation where space is limited.

Open Impeller The open impeller design helps reduce axial thrust and supports solids handling.

Hard Iron Liquid End Abrasion-resistant construction for sand-laden and solids-containing fluids.

Replaceable Stuffing Box Simplifies seal replacement and maintenance.

Renewable Wear Parts Replaceable wear components help manage hydraulic wear and extend service life.

Flexible Drive Options The Sandmaster can be configured for electric motor, engine or hydraulic motor drive. An optional outboard bearing arrangement can accommodate SAE B, C and D hydraulic motor adapters.

Adjustable Discharge Orientation The discharge nozzle can be positioned in different orientations for easier equipment integration.

Sandmaster 6x5x11 Recommend Parts

Sandmaster 6x5x11 centrifugal charge pump is fully dimensionally and hydraulically interchangeable with current market offering pumps of the same size. This means:

Spare parts from standard OEM equivalents fit directly
Existing piping and baseplate layouts require no modification for retrofit
Customers can source wear components from Sandman, reducing downtime risk
Commonly replaced wear parts include the casing, impeller, wear pad, shaft sleeve, stuffing box, and mechanical seal.

Drive Configuration Options

Sandmaster 6x5x11 sand pump is built to be versatile on the drive side as well as the wet end. It can be configured with:

• Electric Motor Direct-Coupled Drive
Directly driven by an electric motor for reliable and efficient operation on fixed installations and drilling equipment.

• Pulley & Belt Drive
Flexible speed and installation configuration, suitable for applications where the pump is driven from a separate motor or engine.

• Diesel Engine Drive
Provides an independent power source for remote and mobile applications where electric power is unavailable.

• Hydraulic Drive
Ideal for mobile drilling rigs, well-service equipment, and other equipment with an existing hydraulic power system.

This flexibility means the same base pump can be dropped into a wide range of skids, trailers, and rig packages without requiring a custom design for each prime mover type.

Sandmaster Pump Typical Application

Sandman^® Sandmaster 6x5x11 transfer pump's compact frame and heavy-duty internals make it especially popular in mobile and space-constrained settings, including:

Cementing units - supplying and circulating cement slurry during well cementing operations.
Charge pump duty - feeding higher-pressure pumps on a rig.
Blender feed pumps - moving fluid into and out of mixing/blending equipment.
Water-well drilling rigs - circulating drilling fluid on smaller, mobile rig platforms.
Desanders and desilters - supplying drilling fluid to solids-control equipment to keep it running efficiently.
Mud mixers - feeding jet mixers used to blend drilling mud additives.
General oilfield and industrial transfer duty – anywhere a compact, high-durability centrifugal pump is needed for abrasive or solids-laden fluids.
