The Ultimate Guide to Pneumatic Slurry Pump Selection for High-Viscosity Transfer

In high-viscosity slurry transfer applications, traditional electric centrifugal pumps often suffer from motor overload, flow decay and even blockage. Pneumatic slurry pumps, powered by compressed air, are inherently safe with low shear force, and have become the preferred solution for coatings, inks, adhesives and food slurry industries.

Three core dimensions of selection: First, viscosity matching. The FY series pneumatic slurry pump can transfer slurries up to 120,000 CPS at 25°C. A viscosity margin of 20%+ is recommended to cope with viscosity rise in low temperatures.

Second, particle passability. For slurries containing fillers or pigment particles, confirm that the maximum particle diameter is smaller than the pump's allowable particle size. FY series handles φ0.8-5mm particles depending on the model.

Third, explosion-proof and environmental requirements. Pneumatic drive produces no electric sparks, naturally suitable for flammable environments. Food and cosmetics industries should choose 316L stainless steel models with quick-disassembly cleaning.

A common mistake is selecting pumps by motor power. For pneumatic pumps, the key parameters are the cylinder pressure ratio and air supply pressure. We recommend consulting our technical team with your actual working conditions for a free assessment.
