Dramm Hydra Spray Guns, Nozzles & Accessories
About this product
Spray guns, nozzle tips, and application accessories for the Dramm Hydra hydraulic sprayer line equip the 550 PSI discharge circuit for broadcast spray, spot treatment, and drench application in greenhouse, nursery, and controlled-environment production. The components below cover the MD-9 stainless steel spray gun platform, interchangeable orifice tips, trigger gun service parts, a drench adapter assembly, and corrosion-resistant hardware upgrades. Each component is specified on its own terms and fits the Hydra assemblies named with it.
Spray Guns- Stainless Steel Spray Gun - Adjustable Output - Includes #4 Tip: Stainless steel trigger spray gun for Hydra sprayers, with an adjustable output pattern. Ships fitted with the #4 nozzle tip (1.5 mm orifice). Constructed in stainless steel for corrosion resistance in high-humidity and corrosive-chemical service.
- Stainless Steel Spray Gun - Adjustable Output - Includes #4 Tip - Male Quick Connect: The same stainless steel adjustable-output spray gun with #4 tip, terminated with a male quick-connect coupling for direct mating to compatible Hydra quick-disconnect plumbing.
Orifice tips for the Hydra spray gun, threaded for interchange on the gun outlet. Flow values below are the published ranges at 200 to 600 PSI supply pressure; select the orifice to match the required application rate and target coverage.
| Nozzle size | Orifice | Flow rate at 200–600 PSI |
|---|---|---|
| #2 | 0.8 mm | 1.38 L/min |
| #4 | 1.5 mm | 3.8–11.4 L/min |
| #5 | 2.0 mm | 7.6–19.0 L/min |
| #6 | 2.5 mm | 37.9–72 L/min |
| #8 | 3.0 mm | 11.4–30.3 L/min |
| 1.0 mm tip | 1.0 mm | 0.62–1.0 GPM (2.3–3.8 L/min) |
| 1.5 mm tip | 1.5 mm | 1.26–1.9 GPM (4.8–7.2 L/min) |
| 2.0 mm tip | 2.0 mm | 2.2–3.0 GPM (8.3–11.4 L/min) |
| 2.3 mm tip | 2.3 mm | 2.7–4.9 GPM (10.2–18.5 L/min) |
| 3.0 mm tip | 3.0 mm | Published for gun outlet thread fitment |
The MD-9 numbered nozzles (#2 through #8) and the millimeter-denominated tips (1.0–3.0 mm) are specified in different flow scales by the manufacturer; both styles fit the Hydra gun outlet for which they are designated. Confirm thread and seating compatibility against the specific gun body before mixing styles.
Gun Service Components- Gun Nozzle Retainer: Retaining fitting securing the nozzle tip in the Hydra spray gun outlet.
- Trigger Gun Repair Kit: Seal and internal components restoring the valve function in the Hydra trigger gun; used when the gun leaks at the valve or fails to hold trigger-off shutoff.
- Replacement Trigger: Trigger lever replacement for the Hydra trigger gun.
- Drench Adapter w/Quick Connect, Fittings, & Wand: Assembly converting the Hydra discharge to a drenching lance, consisting of a quick-connect fitting, connecting fittings, and a wand for directed soil or media drench application at root zone level.
- SprayTrax Spray Shield: Shroud attachment for the Hydra SprayTrax configuration, limiting off-target droplet movement and directing spray at the application target.
- CRF Upgrade Kit: Hardware upgrade converting standard Hydra spray equipment to corrosion-resistant-fitted (CRF) configuration for handling aggressive spray solutions; includes the fittings and components of the CRF specification in a single upgrade package.
- Broadcast foliar application of fungicides, insecticides, and miticides at selectable flow rates via interchangeable nozzle orifices
- Drench application of insecticides, fungicides, and plant growth regulators to soil or container media via the drench adapter and wand
- Spot treatment with the adjustable-output stainless steel gun on electric (4 gpm) and gasoline (7 gpm) Hydra units
- Shielded application on SprayTrax units where drift or off-target contact must be minimized
- Compatibility is stated per component against the Hydra assemblies named with it; verify gun thread, tip seating, and quick-connect style before ordering for a specific unit.
- Nozzle flow ranges above are published at 200–600 PSI supply pressure; the Hydra's maximum working pressure is 550 PSI, so operate within the lower of the component or system rating.
- Verify seal and elastomer compatibility in gun repair components with the chemicals being sprayed, per the product label directions.
- Depressurize the gun and discharge line before changing nozzles or servicing the trigger valve.
- The CRF upgrade kit applies to the Hydra configuration named with it; other corrosion-resistant components are specified individually in their descriptions.
- Flush the gun, tips, and drench wand with clean water after each chemical use.
- Remove and clean nozzle orifices when clogging is observed; never clear an orifice with metal objects.
- Drain the discharge line and gun before freezing conditions.
- Store nozzle tips dry to prevent orifice corrosion.
