SHURflo 9300 Solar Submersible Well Pumps
12 24 Volt DC Positive Displacement

The SHURflo 9300 is a positive displacement diaphragm type pump with very high efficiency that can be operated on 12 or 24 VDC battery bank, or with the use of one of the SHURflo pump controllers  directly with a PV array. The pump can lift 1.3 gallons per minute to 230 feet of total dynamic head and can pump nearly 2 gallons per minute from shallow wells.  If you are looking for a complete system see the Shurflo 9300 Solar Pump Kits page.

SHURflo 9300 Pump Controllers optimize your solar water pumping system by translating the current and voltage available from your photovoltaic panels into a combination better matched to the pump requirements. With an optional float switch installed, the controller will automatically stop pumping when the storage tank is full.

The pump measures 3.75 inches in diameter and is 12 inches long to fit in a 4 inch or larger casing.

The performance of the SHURflo 9300 is at its best when using 24 volts and a SHURflo pump controller which optimizes your solar water pumping system by translating the current and voltage available from your photovoltaic panels into a combination better matched to the pump requirements.

Performance on a 12 VDC battery or solar array will be much less than half the flow shown on the table below.

SHURflo 9300 Solar Pump Controllers

The SHURflo solid-state controllers will protect the 9300 pump from over-voltage and over-current conditions and will provide current boosting in low sunlight conditions, providing both protection and maximum water delivery.  With an optional float switch installed, the controller will automatically stop pumping when the storage reservoir is full.

SHURflo 902-100 Controller

The SHURflo 902-100 Controller is not waterproof so it must be mounted in a dry location or in an appropriate weather-tight enclosure.

Use with a 24 VDC nominal PV array with two 36-cell 12 VDC solar modules wired in series or a similar sized 24 volt panel.

Maximum input voltage is 45 VDC, and max output is 28 VDC and 5 Amps.

SHURflo 902-200 Controller

The 902-200 includes a weatherproof enclosure suitable for outdoor mounting.

The SHURflo 902-200 controller has all the features of the 902-100 and more. This controller has switch selectable for 12 or 24 VDC operation and includes a manual on / off switch for easy pump maintenance.

The 902-200 controller comes complete with high / low water level sensors and sensor wire. Water sensors hang in the well and are used to prevent dry-running in low yield wells. Maximum input voltage is 45 VDC, and the maximum output is 28 VDC and 7 A. Use a single 36-cell 12 VDC module for reduced water delivery or two in series to make 24 VDC nominal for the best operation.

A single common 60-cell 24 volt solar PV module can also be used with either controller, and needs to  produce the 4 A maximum current that the pump draws with only about 50% of full sunlight. This will increase the amount of water delivered per day by increasing water output early and late in the day or in cloudy weather.

Wiring Recommendation

To reduce current loss and plug corrosion in SHURFLOflo 9300 installations, always use a #10 AWG, 2 conductor, no ground, solid core submersible pump cable. The selected pump cable needs to have a smooth outer jacket with no “valleys" in the shape (round or oval) in order to properly seal out water. The submersible pump cable SHURflo 10-2C is recommended.

Maintenance Recommendations and Warranty

The 9300 carries a 1-year warranty and the pump should be pulled out of the well at least every 2 years to replace the brushes, diaphragm, and valves. Occasionally, the cable plug, which is the connection between the cable and the pump, also needs to be replaced due to corrosion or abrasion.
