Hose pumps can transport chemically crystalline materials without damaging their structure
Thread Content
Soft-seal pumps are capable of transporting chemically crystalline materials without damaging their structure. The primary concern for designers and users of such pumps is their ability to handle highly abrasive media; they have no valves or seals, and the only component that comes into contact with the medium is the inner lining of the rubber hose. The rotor that compresses the hose is completely separate from the medium. Hose pumps are an ideal choice for transporting highly corrosive, viscous, shear-sensitive media.
The pump itself does not have any metal parts in contact with large areas, which gives it excellent corrosion resistance. It is particularly suitable for transporting clean fluids or those with high viscosity. However, it should be used with caution when dealing with fluids that contain hard particles, substances that stick easily, or those that settle over time.
Of course, within a certain range for particle size and content, it is recommended to use a hopper as an accessory for sedimentary media.
