When hooking up a DC pump, which has relatively lower suction capabilities when compared with an AC pump, you must take extra care with the input suction line. First, the suction line cannot afford to have any vacuum leaks. Any air getting into the suction line will severely hamper the pump's operation. Second, there should be no ups and downs in the input pipe-line. Any "hump" in this line is a place where air can migrate out of the water or otherwise collect, to form an eventual vapor lock. This can put a severe strain on the pump, and cause the pump to fail. If your pump suddenly seems weak or extra noisy, check your suction line for vapor lock or vacuum leaks.

309-001 Pump Wire $1.49/ft. Use this special #10 ga. 2-lead pump cable to wire the 9300 series pump. The pump connector requires this wire in order to avoid leaking water into the pump.

DC Pump Controller

Model 902-200

921-200 Model 902-200 Controller $299

Boost your 9300 Series pumps performance by up to 30% or more. Shurflo's DC pump controller optimizes your solar water pumping system by translating the current and voltage from your DC power source into a combination that is better matched to that needed by the pump. It also provides your pump with protection from excessive or insufficient voltage. The controller has the ability to automate your pumping system, ensuring that the pump does not run when the water level is too low (level sensing probes are included), or the reservoir is full (float switch must be added). The 902-200 works on 12 or 24 volt systems.

SHURflo Installation Kit

922-001 Install Kit for Pump Models 144 - 12V & 24V, and 534 $25

One idiosyncrasy of diaphragm pumps is noise. They are not loud to listen to but they may transmit vibrations through your plumbing system. This problem is solved with some flexible pipe between the pump and the home plumbing. We offer an installation kit with all the necessary parts to install the pump while minimizing noise transmission.

This kit consists of one intake strainer, two 18" long pieces of high pressure flexible hose, and the fittings and clamps needed to install a SHURflo pump in a home. On the intake side, our last fitting goes into a standard one inch poly underground piping. We also include a 1/2 inch threaded fitting to begin the intake side. On the output side of the pump our last fitting goes to a standard 1/2 inch pipe fitting. You must then go to your pressure tank etc. Installation instructions and diagrams are included.
