up to 6 mm

Your fluid contains solids up to 6 mm? Here you find all pumps with a maximum solids passage of at least 6 mm.

Air-operated diaphragm pumps handle solids gently without rotating parts that could clog or wear. The passage through the valves is decisive: ball valves suit fine to medium solids, flap valves large and fibrous solids. A high solids content increases the density of the fluid – then rather choose a larger size.

Typical applications

Ceramics: pottery slip, glazes, clay
Abrasives: clay slip, titanium dioxide, sinter materials, lime slurries, cements, scale
Waste water & sludge: waste water, filter press feed, sewage sludge, softening and lime sludges, coal and coke slurries

Consider density and viscosity

Density and viscosity of the fluid are decisive for the selection – they have a considerable influence on the effective flow rate. Viscous fluids such as resins, adhesives or chocolate reduce the flow significantly and require larger suction lines and a slower stroke rate. Heavy fluids such as slurries or cements increase the required air pressure. Please state density (kg/dm³) and viscosity (mPa·s) in your enquiry.
