1HP Oil transfer pump with 43psi pressure relief. Perfect for hose reel applications where flow will go to zero before the pump can be turned off (pump must still be turned off as soon as possible to prevent overheating).
- POWERFUL 1HP OIL TRANSFER: Heavy-duty gear pump with a massive Baldor Motor.
HOW THEY WORK
Twin rotary gears are set in the pump body. One is active, the other is passive. Active gear drives passive gear to rotate when pump works. As gear teeth unite then sever, vacuum/suction is created in pre-chamber. Liquid fills the gear cavities and is pushed at high pressure out from the chamber.
SAFETY RELIEF VALVE
Safety valve is set from factory. Safety valve is automatically opened when pump or output piping receive excess pressure. Once valve opens, pressure and oil is routed back to the inlet chamber and re-circulated through the pumphead.

FAQs
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.
