The present invention provides a quick startup device for a centrifugal pump. The device includes an upper self-priming chamber, a lower self-priming chamber, and an inlet pipe sequentially arranged from top to bottom. The upper self-priming chamber and the lower self-priming chamber are integrally mounted on the inlet pipe. A main shaft and a hexagonal partition member rotatably mounted on the main shaft are arranged on an axis of the upper self-priming chamber. A blade tip of each partition plate is closely attached to an inner wall surface of the upper self-priming chamber. Three identical accommodation grooves are provided on an inner side of the upper self-priming chamber. A spring and a separation baffle are arranged in each accommodation groove, an exhaust hole is provided on one side of each accommodation groove, and an air intake pipe is provided on the other side of each accommodation groove.

A self-priming starting device for a centrifugal pump is mounted on a water inlet pipe of the centrifugal pump and includes an outer housing, an inner housing, a primary spacer, a secondary spacer, an opening and closing disc and a tertiary spacer which are sequentially provided in the outer housing from top to bottom, and an elastic steel plate provided in the water inlet pipe. A drum is provided in the inner housing, and air inlet pipes and air discharging pipes are provided on the inner housing. The drum is provided with drum chambers and a three-blade support is provided in the drum. The opening and closing disc is provided with a vertical rod. A gas-liquid cutter is provided between the primary spacer and the secondary spacer. The primary spacer, the secondary spacer, the opening and closing disc and the tertiary spacer are provided with through-holes.

A pumping system including a pumping chamber with a fluid sensor having a cylindrical shaft extending into the priming chamber. The sensor has a sensing dome on an end of a cylindrical shaft extending into the priming chamber, with the dome having a vertical base having a diameter less than the cylindrical shaft diameter. The sensor signals a controller whether liquid is present based on an algorithm with settings for dampening of the electromagnetic field, conductance of the electric field, and/or permittivity of the magnetic field using settings which correlate to the fluid environment. The controller controls operation of the pump and primer based on the sensor signal.

Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller is configured to store a timeout time value. The controller is also configured to initiate a pump priming process and subsequently initiate a timeout counter to begin counting a counter time value. The controller is configured to initiate a timeout interrupt routine that interrupts the pump priming process when the counter time value exceeds the timeout time value. The timeout interrupt routine includes shutting down the motor.

A centrifugal pump to improve the efficiency of fluid flow r, and minimize long term wear on the pump by progressively increasing fluid pressure as fluid moves from an eye of an impeller towards diffuser blades, into the volute and out through a outlet. The fluid pressure is increased by progressively increasing the volume through which the fluid travels. A tear-drop shaped volute casing surrounding the diffuser and impeller creates a pocket of maximum pressure just below the outlet. A dampener can be provided to dampen the vibration of the motor. A cylindrical basket strainer can be provided with a flat face abutting against the volute casing to distribute pressure evenly, A clamp ring can be provided to easily seal and access the basket strainer using a plain rod.
