Dramm - Hydra 50 Gallon Sprayer Replacement Parts
Brand: Dramm
Hydra 50 Gallon Sprayer Replacement Parts
These are genuine Dramm service parts for the Hydra 50 gallon hydraulic sprayer: the complete triplex piston pump assembly, the sealed 1.5 HP electric motor, and the pump crankcase. They are the same components the factory fits, so they go back in without modification or adapters. Buy them to bring a worn machine back to full flow and pressure, or to hold as spares on a spray program that cannot afford downtime.
Order the part that actually failed rather than a whole assembly. Part 200020 is the complete triplex piston pump with stainless steel inner sleeves, rated 4 gpm at up to 550 psi - choose it when the pump is worn past what a seal or valve kit will restore. Part 400150A is the sealed 1.5 HP electric motor that runs at 1750 rpm and close-couples to that pump on a shared shaft, for a burned-out or seized motor. Part 210503 is the pump crankcase on its own, for a rebuild where the crankcase is the damaged component and the rest of the pump is still serviceable.

Key Features
- Genuine Dramm factory parts, the same units fitted to new machines
- Complete pump assembly available so you are not rebuilding a pump in the field
- Triplex piston pump uses stainless steel inner sleeves that resist pitting and corrosion
- Motor sold separately from the pump, so one failure does not force replacing both
- Crankcase offered on its own when a full pump assembly is more than the repair needs
- Close-coupled design means no belt tensioning or alignment on reassembly
Ideal Applications
- Restoring flow and pressure on a Hydra 50 that has worn past a seal kit
- Replacing a seized or burned-out 1.5 HP sprayer motor
- Rebuilding a pump where the crankcase is the damaged component
- Stocking critical spares for operations that spray daily through the season
- Planned replacement during off-season equipment service
These parts fit the Hydra 50 Gallon Cart Sprayer and the 115 V electric Hydra SprayTrax 50; check the part number against your machine's serial plate before ordering for any other Hydra model.
