Factory Refurbished 12gpm oil transfer pump 3/4hp

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 12 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 unit features a Custom US-Made Baldor Motor engineered specifically for WVO. It comes pre-wired with a heavy-duty switch and power cord, meaning it is ready to pump right out of the box.
