The ultimate heavy-duty transfer system. We pair our flagship cast-iron positive displacement pumphead with an industrial-grade US-made Baldor motor for fast, open-ended transfer of light to heavy viscosity oils at a reliable 25 GPM.
Engineered to provide a truly robust, high-volume transfer solution, the Monster Transfer Series is built modularly. By combining a dedicated, heavy-duty fluid pumphead with an industrial-grade electric motor, we've created a self-priming, continuous-duty system built to excel in demanding environments and optimized for specific fluid applications.
The Heart + The Muscle (Our Modular Philosophy)
Our pumps are designed as true fluid transfer systems by pairing a specialized pumphead (The Heart) with a powerful electric motor (The Muscle). This allows us to create the perfect tool tailored for your specific viscosity and application needs.
Component 1: The Monster GSM25 Pumphead
At the heart of the system is the GSM25—a direct-drive, cast-iron positive displacement gear pumphead. It utilizes large displacement, helical-cut steel gears for incredibly fast, quiet, and pulseless fluid transfer. It is inherently self-priming, relies on the fluid you pump for internal lubrication, and features high-temp Viton seals.
Component 2: The Electric Motor
Because moving thicker fluids efficiently requires substantial torque, we match the pumphead with a power plant built to handle the load. This bare pump assembly features a Stock US-Made Baldor Motor. It is shipped without a handle or wiring, providing an excellent foundation for hardwiring the pump into a custom skid, processing system, or existing shop infrastructure.
