The compact, easily useable metering pump results from a structure including a housing (20) with a pumping chamber (34) within the housing (20). A diaphragm (36) is located in the pumping chamber (34). An inlet includes a check valve (50) for allowing fluid to flow to one side of the diaphragm (36) but not the reverse and an outlet including a check valve (56) allows fluid to flow from the pumping chamber (34) but not into it. A pneumatically operated hydraulic pump (16) is located in the housing (20) and cycles the diaphragm (36).
Cette pompe doseuse compacte, et facile à utiliser comprend un corps (20) qui contient une chambre (34) de pompage. Une membrane (36) est disposée dans cette chambre (34) de pompage. Un orifice d'admission équipé d'un clapet (50) de non-retour permet au fluide de passer d'un côté de la membrane (36) mais l'empêche de revenir en sens inverse, et une sortie comprenant également un clapet (56) de non-retour permet au fluide de s'écouler hors de la chambre (34) de pompage mais l'empêche d'entrer de cette dernière. Une pompe (16) hydraulique pneumatique est montée dans le corps (20) et actionne la membrane (36).
