The pumps are commonly used in the winemaking, food, chemical, cosmetic and pharmaceutical industries. The flexible impeller vanes deform and withdraw the liquid from inside the pump, continuously transferring it to the outlet (discharge). This principle combines gentle pumping with a high self-priming capacity. Excellent performance even at low speed, allowing the transfer of delicate and fragile fluids with viscosity up to 50,000 cp, also with suspended bodies and without aerating, emulsifying and damaging the solid parts. Pulse-free product transfer (continuous flow, excellent for dosing, filling and filtering).
