A nested dual-valve backflow opening removes suction-side air at low flow while avoiding the permanent power losses of self-priming pumps.
A float closes the evacuation path before liquid reaches the seal, enabling reliable suction line evacuation with turbid or aggressive liquids.
An insertable valve body and accessible seal chamber let pump float boxes replace the seal element quickly without full valve housing disassembly.
Capacitive sensing replaces float switches to prevent damage from liquid surges and reduce maintenance frequency.
An inlet nozzle channels liquid through a pump housing to release dissolved gases, reducing equipment complexity.
Two independent cartridges in a sump pump provide backup operation during high flow or failure.
A widened deceleration chamber in the integrated pump module separates air bubbles from coolant, restoring cooling capacity and pumping rate.
Pressure-adjusted valve in detachable venting device expels accumulated air to prevent impeller damage and ensure autonomous starting.
Truncated vanes on a semi-open impeller homogenize gas-liquid mixtures to prevent gas locking, maintaining pump capacity under high gas-to-liquid ratios.
A priming pump and sensor-controlled valve fill suction piping to prevent flooding damage from insufficient head in remote pool installations.
