I removed this pump from a power washer that was almost never used. I know because I bought it new. The pump is working nicely without significant wear except cosmetically as pictured. Specifications Motor Type: 12 VDC, permanent magnet, thermally protected, splashproof Leads: 2200-1 Models: 18 AWG, 9” long 2200-2, 2200-3 Models: 18 AWG, 4.5” long with 2-pin connector Duty Cycle: Intermittent Pump Type: 2-chamber positive displacement, self priming, capable of being run dry Liquid Temperature: 110°F (43°C) Max. Priming Capabilities: 4 feet (1.2 m) suction lift Max Pressure: 40 PSI (2.8 bar) Pressure Demand Switch: Shut-Off: 40 ±5 PSI (2.8 ±0.3 bar) factory setting Turn-On: 25 ±5 PSI (1.7 ±0.3 bar) factory setting Inlet/Outlet Ports: 3/8” hose barb Weight 1.25 lbs (0.57 kg Installation Recommendations Mounting: Determine the optimum location for your pump. 1. PowerFLO ™ 2200 Series pumps are self-priming and can be located up to 4 feet above the water level. Horizontal and vertical prime vary depending on the fluid viscosity and pump configuration. The pump can be at the same level or below the tank. 2. The pump should be located in an area that is dry and protect the pump from excessive heat by providing proper ventilation. The pump can be at the same level or below the tank. 3. The pump can be mounted in any position. Since the pump head and motor are splash proof, water should not be a concern no matter how the pump is mounted. However, the switch cover does have an opening at the bottom which could collect water if the pump is mounted with the head down. Plumbing: 1. Use suction hose on inlet of pump. Use flexible hose of the correct pressure rating that is compatible with the fluid to be pumped. 2. Pump will prime only if all pressure is relieved from outlet port. 3. It is recommended that pure water be pumped or an in-line sediment filter (50 mesh) be installed at the inlet side to keep foreign debris out of the system. If a check valve is installed in the plumbing, it must have a cracking pressure of no more than 2 psi (0.14 bar) 4. Avoid any sharp bends which may crimp tubing and restrict flow. Use 90° elbow fittings if necessary. 5. The pump should always be mounted prior to any components which could introduce particles to the water; thus, preventing them from entering the pump chambers and possibly causing clogging. Electrical: 1. 12 volt pump must be provided with a 5-amp fuse. 2. Recommended wire size is 18 gauge (1.3 mm) or larger wire as determined by voltage drop. Negative must be connected to a known ground. Ground wire must be the same gauge/mm as the positive. Operation Precautions 1. Do not operate pump in an explosive environment. Arcing from the motor brushes, switch or excessive heat from an improperly cycled motor may cause an explosion. 2. Do not pump gasoline or other flammable liquids. 3 Do not assume fluid compatibility. If the fluid is improperly matched to the pumps’ elastomers, a leak may occur. 4. Intermittent duty is defined as operation and/or frequent starting within a period of time that would cause the motor to reach its maximum thermal limits. Once the maximum is obtained, the motor must be allowed to return to ambient temperature before resuming operation. Troubleshooting Guide Problem/Causes and Remedies Pump will not Start Check: • Correct voltage (±10%) and electrical connections • Fuse or breaker • Pressure switch operation and correct voltage at switch • Rectifier or motor for open or grounded circuit • Locked drive assembly Pump will not Prime (No discharge with motor running) Check: • Debris in strainer • Restriction (kinks) in inlet/outlet tubes • Debris or swelling in inlet/outlet valves Pump will not Shut Off (Output line closed and no leaks) Check: • Air trapped in outlet line or pump head • Correct voltage to pump • Debris in pump inlet/outlet valves • Loose drive assembly or pump head screws • Pressure switch operations/adjustments Leaks from Pump Head or Switch Check: • Loose screws at switch or pump head • Switch diaphragm ruptured or pinched • Punctured diaphragm if fluid is present
