Select a flap valve diaphragm pump using the actual solids size, shape, concentration, fibres, viscosity and abrasiveness. Confirm valve passages, model limits, wetted materials, suction conditions and the operating point. Follow model-specific priming and dry-running instructions. Evaluate blockage, wear and product quality with the actual material; the valve type alone does not establish suitability for every slurry.

Evaluate blockage, wear and product quality with the actual material; the valve type alone does not establish suitability for every slurry.
Specify solids size, shape, concentration, hardness and abrasiveness together with viscosity and settling behaviour. The listed particle limits differ by model: 25 mm for 1.5 inch, 38 mm for 2 inch and 50 mm for 3 inch. These limits do not establish passage of every particle shape or fibrous material.
Check suction layout, pipe bore, bends, settling zones and cleaning access. Maximum flow and pressure are not achieved simultaneously. Compare the complete valve and wetted-material configuration, and evaluate a representative sample when solids may bridge or damage valves.
