Misting System Pump
Industrial and commercial misting systems live or die by the quality of the pump. A well matched, correctly sized pump keeps water atomising at the optimal pressure, delivers ultra fine droplets, and runs 24/7 without overheating or stalling. Below we dive into the three pressure classes—high, mid and low—explain common applications, and compare India’s most trusted brands so you can choose the perfect unit for your plant, factory, dairy, greenhouse or outdoor venue.
Why Pressure Matters in Misting
Droplet Size
Higher pressure means smaller droplets (10–30 µm) that evaporate faster and cool more efficiently.
Coverage & Drift
Correct pressure minimises wetting of nearby surfaces while maximising reach.
Pump Longevity
Over or under specification leads to cavitation, seal wear and energy loss.

Selection Checklist
Calculate total nozzle flow (l/min) + 15 % safety margin.
Match pump curve at desired pressure and flow.
Confirm NEMA/IEC motor frame compatibility.
Factor water quality—use RO or soften > 150 ppm hardness.
Plan service intervals: change oil every 500 hours; check seals every 1,000 hours.
Frequently Asked Questions
1. What is a misting pump and how does it work?
A misting pump pressurises water—up to 70 bar in some models—and pushes it through micron size nozzles to create an ultra fine mist that evaporates instantly, absorbing heat and cooling the surrounding air.
2. How do I choose between high, mid and low pressure pumps?
Match pump pressure to your application: low pressure units are fine for patios; mid pressure excels in greenhouses; high pressure (30 bar+) delivers flash evaporation critical for industrial cooling and dust control.
3. Which brands of misting pumps do you supply in India?
We are authorised distributors for **CAT”, “Annovi Reverberi”, “HAWK” and Riggers pumps—covering every budget and performance tier.
4. Are belt drive or direct drive pumps better for continuous operation?
Belt drive pumps run cooler and are quieter, making them ideal for 24/7 duty; direct drive pumps are more compact with lower upfront cost but may require more frequent maintenance in heavy duty scenarios.
5. What maintenance does a misting pump require?
Routine tasks include replacing oil every 500 hours, cleaning or swapping inlet filters, and inspecting seals & valves—simple steps that extend service life and prevent downtime.
6. Can misting pumps be used for industrial cooling?
Yes—our high pressure CAT, AR and HAWK units are engineered for harsh industrial environments, providing rapid evaporative cooling, dust suppression and humidity control across factories and warehouses.
7. What warranty do your pumps carry?
All pumps ship with a 12 month manufacturer warranty; extended 24 or 36 month coverage is available via our Annual Maintenance Contracts (AMC).
8. Do you provide installation and after sales support?
Absolutely—our in house technicians handle system design, on site installation and user training. We also stock genuine spare parts to keep your system running smoothly.
