    WVO Designs 4gpm Portable Oil Transfer Pump, Raw Power Monster Gear Pump

    • UPGRADED PORTABLE OIL TRANSFER GEAR PUMP 4GPMOur previous vegetable oil pumps were less effective for pumping cold motor & gear oils. In response, we engineered the new Heavy Duty Oil Pump — a portable and efficient oil transfer pump designed for high-viscosity fluids. The transfer fuel pump upgrades include (a) a robust US-made 1700RPM Baldor motor, capable of moving motor oil and gear oil, (b) Viton seals on the pump heads, and (c) the elimination of troublesome pressure regulators.

The Raw Power® Monster Gear Pump is a self-priming, portable, close-coupled rotary gear pump designed to transfer heavy oils fast!

    FAQs

    Find quick answers to common questions

    Product & Usage

    1. Are Goldstream pumps built for professional use?

    Yes. Every Monster Series and Industrial Series pump is built for continuous duty, marine environments, and the kind of fluid-transfer work that breaks cheaper pumps.

    2. Can I use a Goldstream pump for my home project?

    Absolutely. Our Monster Series is portable and self-priming — no tuning or tricks needed. Plug it in and move fluid.

    3. Can Goldstream pumps be used in marine or outdoor conditions?

    Yes. Goldstream pumps are tested in real-world marine, biofuel, and industrial conditions — heat, humidity, and long runtimes.

    Maintenance & Accessories

    1. What maintenance does a Goldstream pump need?

    Flush with a compatible fluid after each use and keep seals clean. That's it — our gear pumps are built to run with minimal fuss.

    2. Can I buy replacement parts?

    Yes. Seals, impellers, gaskets, and full rebuild kits are in stock at the Pump Parts collection.

    3. Do you provide installation guides?

    Every pump ships with a printed install guide. Digital copies and install videos are linked from each product page.

    Warranty & Guarantee

    1. Do Goldstream pumps come with a warranty?

    Every Goldstream pump is backed by our 1-year limited warranty against defects in materials and workmanship, when used with approved oil-based fluids.

    2. How do I register my pump for warranty coverage?

    Keep your order confirmation email — it acts as proof of purchase. You can also register your serial number in your account for faster service.

    3. What does the warranty cover?

    Defects in materials and workmanship under normal use — no fine print, no games. Wear items (seals, gaskets) are covered by a separate 1-year warranty.

    4. What if my pump fails?

    Call us. We'll get you a replacement or rebuild fast — usually the same week.
