Dramm Hydra Pump Replacement
About this product
Replacement pumps for the Dramm Hydra hydraulic sprayer, available in gasoline-engine and electric-motor configurations. The Hydra is a high-volume, multi-spray hydraulic sprayer used for the application of insecticides, fungicides, growth regulators, liquid fertilizers, disinfectants, and other crop-protection solutions in commercial greenhouse, nursery, and cultivation operations. Both pumps are durable triplex (three-piston) positive-displacement pumps in a close-coupled configuration, mounted directly to the drive to eliminate the belts and chains that act as wear points and maintenance burdens on conventional sprayers.
Pump Configurations
| Configuration | Drive | Pump Output | Maximum Operating Pressure |
|---|---|---|---|
| Electric Pump Replacement | Sealed 1.5 HP electric motor (virtually maintenance-free) | 4 GPM (gallons per minute) | 550 PSI |
| Gas Pump Replacement | Gasoline engine | 7 GPM | 550 PSI |
Construction and Design
The triplex pump uses three reciprocating pistons to deliver smooth, high-volume, high-pressure flow with low pulsation. The output volume is sufficient to operate a spray gun while simultaneously driving the Hydra's agitation system, which keeps wettable powders and granular formulations in uniform suspension from the first gallon to the last. The close-coupled design removes belt and chain drives, reducing downtime and routine maintenance. Pump pressure is set through the Hydra's fully adjustable regulator, which supports approximately 20 combinations of droplet size and spray distance for matching application to target and chemistry.
Performance Context
- Maximum operating pressure: 550 PSI, fully adjustable via regulator
- Electric motor output: 4 GPM at 1.5 HP, sealed and close-coupled
- Gas engine output: 7 GPM for higher-volume or off-grid operation
- Standard system gun output: approximately 1.3 GPM with a choice of spray patterns
Compatibility and Service
For use as a replacement pump on the Dramm Hydra 50-gallon sprayer and Hydra SprayTrax cart systems. The Hydra pump is a serviceable, triple-piston design; individual wear components are also field-replaceable, but a complete pump replacement restores full rated output and pressure when internal wear has degraded performance.
