Major ASPEE spray pump models and categories
ASPEE manufactures manual and mechanized sprayers tailored to diverse acreage and crop heights.
- Manual Knapsack Sprayers (such as ASPEE Bakpak): 13 to 16 liter chemical tanks with durable brass pressure chambers for smallholder farmers.
- Battery-Operated Knapsack Sprayers: Dual-operation 12V battery pumps providing consistent pressure without manual pumping effort.
- Engine Power Sprayers: 2-stroke or 4-stroke petrol engine sprayers delivering high pressure for tall orchard trees and dense canopies.
- Tractor-Mounted HTP Sprayers: High-pressure triplex plunger pumps driven by tractor PTO for large-acreage spraying.
- Rocker and Foot Sprayers: Heavy-duty pumps designed for coconut groves, betel nut plantations, and fruit orchards.
Nozzle selection and spray calibration
Matching nozzle types to agrochemical formulations prevents drift and ensures target coverage.
- Hollow Cone Nozzles: Recommended for insecticides and fungicides requiring fine mist droplets for upper and lower leaf wetting.
- Flat Fan / Flood Jet Nozzles: Deliver larger droplets in a fan pattern, ideal for soil and post-emergence weed killers.
- Calibrate sprayer output using clean water before mixing chemicals to confirm precise liquid volume per acre.
- Clean nozzle filters and tips using a soft nylon brush; never use metal wires that distort nozzle orifice geometry.
Maintenance routines and government subsidies
Routine upkeep prevents pump corrosion, while central schemes assist equipment procurement.
- Flush the tank, hose, trigger valve, and lance with clean water immediately after every spraying operation.
- Grease pump piston packings and lubricate mechanical joints according to manufacturer maintenance intervals.
- Subsidies available under the Sub-Mission on Agricultural Mechanization (SMAM) and state DBT portals.
- Apply through the official agricultural mechanization portal (agrimachinery.nic.in) using your Aadhaar and land records.
