GMS proudly delivers high-performance 250 Sandmaster Pump solutions engineered to meet or exceed OEM standards. Trusted by oil and gas operators, drilling contractors, and EPC companies, our pumps ensure reliability in the most demanding environments.
Compact. Powerful. Exceptionally Versatile.
The Sandmaster Centrifugal Pump is engineered for performance in tight spaces without compromising power. Designed with all the key features of the Magnum I, this compact solution stands out for its ability to seamlessly integrate with hydraulic motor drives—making it a top choice for oilfield fracturing units, water well mixing systems, and pump charging operations.
What sets the Sandmaster apart? A shorter frame and shaft—trimmed by 4 inches—significantly reduce the pump’s overall length, giving you greater flexibility where space is at a premium and prime mover options are limited. And with full compatibility of internal components with the Magnum, it delivers both reliability and cost efficiency.
When space is tight, choose Sandmaster—engineered for performance where it matters most.
Stable Performance
The product is designed to deliver stable and reliable performance in even the toughest conditions.
Industry Standards
Our product is fully compliant with international standards, including ISO certifications, ensuring that it meets the highest safety and quality benchmarks.
