SHURFLO 9300 series submersible pumps are designed for reliable small-scale water supply from boreholes and wells and are the ideal solution for remote pumping requirements in livestock watering, irrigation and general water supply applications. They are of positive displacement three-chamber diaphragm design and can run dry without damage. An internal bypass is also incorporated to prevent pump damage in the event of delivery cut-off.
Pump components are manufactured from high quality engineering plastics with santoprene used for the diaphragm and EPDM for the valves. A 50-mesh stainless steel screen is also incorporated.
LINEAR CURRENT BOOSTER PUMP CONTROLLER
A Linear Current Booster pump controller is available which boosts pump output up to 30% by optimizing the power supply from the photovoltaic modules resulting in a longer pump operating period. The controller also provides voltage limiting pump protection, low level pump control with electrodes included, terminals for remote float switch connection and pump 'on' indicator LED all mounted in a compact weather proof enclosure.
The pump motor is of permanent magnet type for 24V DC power input from either a direct source or photovoltaic modules. Internal thermal protection is also provided. Suggested module power ratings are as follows:
