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
