Description
When your Hypro perpump isn’t moving fluid like it should, the problem often comes down to worn gears inside the pump assembly. This gear assembly is what transfers power from your PTO or engine to create the pressure you need for spraying. Without smooth-running gears, you’ll notice reduced flow, irregular pressure, or your pump working harder than it should.
What You’re Getting
- Complete 3-gear assembly designed specifically for Hypro perpump systems
- Precision-machined gears that deliver consistent fluid transfer and pressure
- Durable construction that stands up to the demands of chemical spraying operations
- Direct replacement part that restores your pump’s original performance
Built for Real Farm Work
This gear assembly is engineered for the tough conditions of agricultural spraying, whether you’re applying herbicides in corn, fungicides on soybeans, or handling pasture maintenance. It’s designed to handle the continuous operation that field spraying demands, from dawn-to-dusk spray days during critical application windows.
Made to Last
Hypro builds these gear assemblies to handle the constant rotation and pressure cycles of spray pump operation. The gears are manufactured to tight tolerances for smooth operation and long service life, even when running aggressive chemicals through your system.
Good to Know
Replacing the gear assembly requires draining your pump and disassembling the housing, so it’s a good time to inspect seals and gaskets while you’re in there. Make sure to use proper gear oil when reassembling, and check your pump manual for the correct oil capacity and type.
