Sandman® Mission Sandmaster Centrifugal Pumps with Short Frame that make it ideal for space-constrained mobile applications. It shares many features with the Magnum I series but is more adaptable for hydraulic drives.

Sandmaster Pump Design Features:
The Sandmaster 4x3x13 emphasizes durability, adaptability, and ease of maintenance for harsh, abrasive conditions:
• Compact Heavy-Duty Frame: Space-saving design for tight installations (e.g., frac trucks or drilling rigs); robust cast iron construction withstands high vibrations.
• Full Open Impeller: Reduces axial thrust and shaft loading; semi-open options available for finer solids; impeller is fully adjustable for optimal performance.
• Replaceable Stuffing Box Cover: Easy access for seal replacement without disassembling the pump.
• Abrasion-Resistant Fluid End: One-piece concentric casing with thicker walls; high-chrome alloy components (casing, impeller, wear pads) for extended life in sandy slurries.
• Hydraulic Motor Adaptability: Variable-speed hydraulic drive option for mobile units; direct or belt-driven configurations; short shaft variants for cement pumping.
• Bearing and Shaft System: Oversized shaft with grease/oil-lubed bearings; designed for high radial loads and speeds up to 3,500 rpm
These features ensure low maintenance and high uptime, with the pump fully back-pull-out for field servicing.
Sandmaster Pump Applications:
The 4x3x13 excels in handling abrasive drilling muds, sands, and slurries in oil & gas and industrial settings:
• Oilfield Drilling: Mud mixing/shearing, desanding/desilting, degassing feed, supercharging triplex pumps, and centrifugal feed in solids control systems (up to 3,000m rigs).
• Frac and Cementing: Charge/transfer pump on frac trucks; cement blending and mobile pumping.
• Water Well Drilling: Variable-speed hydraulic drive for drilling fluids; ideal for compact rigs.
• Industrial Services: Wash-down, mud cooling towers, chemical/refinery transfer, construction dewatering, and agricultural irrigation with solids.
• Other: Underground construction, blending/pump charging, and general slurry handling where space is limited.
