Fluid System
Engineered fluid management for consistent, reliable spray performance in every condition.
Diaphragm pumps
The diaphragm pump At the heart of a HARDI sprayer sits the robust and easy-to-service pump that HARDI is so well known for. The invention of this pump constituted the foundation upon which HARDI was founded more than 60 years ago. HARDI was the first to use diaphragms to separate the liquid from bearings, crankshaft and other vital pump parts, thereby allowing the pump to run dry without damage. In addition, this pump distinguished itself by being operated directly from the tractor’s PTO
Filters
CycloneFilter The HARDI CycloneFilter is a unique self-cleaning pressure filter that uses a high-speed cyclone for additional cleaning action. The cyclone action increases the cleaning capacity of the filter significantly. This ensures fewer stops and reduced pressure loss in the liquid system. Furthermore, the HARDI CycloneFilter has a unique boost function that allows the filter to be flushed “on-the-go” when needed. The cyclone created inside the filter increases the speed of the liq
SmartValve
Easy to operate All primary functions needed to operate the sprayer when filling chemicals or cleaning have been built into two main valves. These valves are located in the centre of the working zone. The logically placed handles and the easy-to-read colourcoded icons make the system very easy to understand and operate and greatly reduce the start-up and operation time of the sprayer. If an optional filling system, either PumpFiller or FastFiller, is added, an extra suction val
TurboFiller
High mixing capacity Liquid at high pressure is being used to create a powerful rotation inside the hopper. The rotational movement powerfully mixes powders and liquids as they are drawn into the sprayer. The highest capacity is achieved when the TurboFiller is more than half-filled with water. Very high vacuum and suction capacity A large external ejector system creates a powerful vacuum that transfers powders and liquid directly into the tank. Lance for cleaning A cleaning lance
DynamicFluid4
Fast and precise regulation With precision and capacity in mind, HARDI challenged the traditional way of regulating volume rate. Traditionally, a sprayer applies and then measures actual volume rate. When the rate applied and the volume rate do not match the pre-set volume, the computer system will regulate until they match. This conventional spray systems means that driving speed, boom width and pump revolutions must stay relatively stable to obtain a precise regulation. With tod
EFC Boom Section Valves
Instant shut-off at the nozzles The ElectricFastControl (EFC) is a modular system with a positive drive motor valve for each section and a single pressure dump valve, when all sections are switched to OFF. The section valves incorporate a pressure dump. When the section is switched to OFF, the pressure in the line to the nozzles is relieved. This results in instant shut-off at the nozzles. The EFC does not need any form of adjustment, e.g. pressure equalization.
