A volumetric hand pump having a transparent pump chamber and a fixed full stroke volume. The transparent pump chamber allows visual observation of the amount of fluid being pumped when less than the fixed full stroke volume is used. The transparent pump chamber is surrounded by a housing or shroud which includes one or more windows that allow visual access to the transparent pump chamber. An optional stroke counter can be provided to track the number of full pump strokes, thus allowing accurate dispensing of both large and small quantities of fluids, while providing visual observation of the amount of fluid being pumped and dispensed. The pump is particularly useful for dispensing agricultural chemicals.
Cette invention concerne une pompe volumétrique à main comportant un cylindre transparent à volume fixe en fin de course d'aspiration. Le cylindre transparent permet d'observer la quantité de liquide pompée lorsque la pompe fonctionne à course de pompage raccourcie. Le cylindre transparent est entouré d'un corps de pompe comportant un ou plusieurs hublots par où observer l'intérieur du cylindre transparent. La pompe peut être équipée d'un compteur servant à renseigner sur le nombre des coups de pompage à course complète, ce qui autorise le dosage précis de quantités petites et grandes sous observation visuelle. La pompe est particulièrement utile pour la distribution de produits chimiques agricoles.
