Pumps Pumps With over 120 years experience in plant protection, our pumps are based on the expertise of our engineers in the BERTHOUD design office. Designed, assembled and honed by our Belleville technicians, they are the veritable lungs of the sprayer and have been developed based on your needs to meet the spraying challenges of tomorrow: reliability, high work output, environment - with a view towards maximum integration (accessibility, dead volume reduction) . Each pump is subjected to an individual test protocol to validate its performance and its robustness before the final assembly of the machine.
