Priming Pump TRIZ Cases
- Nested Suction Valve Pump for Air Removal Without Power Loss
A nested dual-valve backflow opening removes suction-side air at low flow while avoiding the permanent power losses of self-priming pumps.
- Float-Controlled Suction Pipe Evacuation for Seal Protection
A float closes the evacuation path before liquid reaches the seal, enabling reliable suction line evacuation with turbid or aggressive liquids.
