Speroni 1HP Deep Suction Well Jet Self Priming Pump, 110/220V – Model APM 100 (P30)

Key Features

This high-performance external ejector jet pump functions as a centrifugal pump that transforms into a self-priming deep well jet pump when equipped with an ejector at the end of the suction line. The system utilizes a Venturi effect to recirculate water, drawing liquid from deep sources and creating sufficient pressure to deliver it to the surface. Designed for deep suction applications up to 114 ft, the system requires two connected pipes: a delivery pipe to the ejector and a return (suction) pipe. For proper installation, the well diameter must be at least 4 inches.

Applications

Ideal for deep well water extraction, this self-priming jet pump is suitable for domestic water supply systems, draining wells and cisterns, small to medium-sized water tanks, and installations with significant vertical water level differences. Before installation, ensure all pipes (plastic, iron, or rubber) are clean to avoid clogging the ejector nozzle. A foot valve or check valve must be installed at the ejector base. After mounting the pump, fill the pump body and both pipes completely with clean water. To maintain effective priming, the system requires stable pressure in the pipeline. We strongly recommend installing a membrane pressure tank at the pump’s delivery outlet.
