10 Points of PS Service
10 POINTS OF PUMP STATION REPAIR
CAUTION: High voltage and high pressure are present in all pump stations. Only persons familiar with the safety requirements of such conditions should perform the following service procedures:
1. Clean filters regularly. Control, bypass, relief valve piloting, heat exchanger and air conditioner strainers need routine cleaning. Whether daily, weekly or otherwise depends on you water conditions. Backwash or “Y” strainers on system discharge - remove screens annually.
2. Tighten all electrical connections annually. With power off, checked and locked, all wires must be tightened, with the exception of small control wires which may be pull checked, then tightened as needed.
3. Keep all painted surfaces clean and touch up paint where necessary. A clean painted system will last much longer than one that is ill kept.
4. Verify electrical conditions routinely. Check incoming voltage for balance both under load and no load conditions. Also monitor system ground resistance values, (values of five ohm’s or less to ground being optimum). A poor ground is problematic with today’s controls and instrumentation.
5. Keep a log of motor conditions, motor winding resistance deteriorates over time. A record of this deterioration will assist in predictive maintenance requirements. A record of motor current at various recorded flow demands will assist in determining both motor and pump performance.
6. Check pump shut off (no flow) pressure regularly. This is a basic indicator of pump condition. In conjunction with increased current at a given flow demand, one can better determine pump wear.
7. Confirm pressure switch and control piloting settings annually. Although these won’t usually change much, other conditions can cause deviations from the original settings. Dirty or corrosive water can be especially troublesome. Sensing lines should be bled and flushed as needed.
8. Annually remove control, bypass, and/or relief valve cover and inspect for accumulation of debris on top of the diaphragm. Clean or replace rubber parts as needed. Inspect valve seat and replace if necessary. If substantial debris is under the cover, the piloting may also require disassembly for cleaning.
9. Exercise any and all ball, butterfly and gate valves at least every 3 months. Valves that are not routinely exercised through their range of motion may not function properly when they are really required.
10. Properly tighten or correct any leak conditions as they occur. This includes replacing gaskets and mechanical seals as needed or adjusting pump packings if provided .
The preceding list is by no means complete. It is however, the most required maintenance common to virtually all pumping systems.
Regardless of make or model, if these points are heeded, major mechanical or electrical failures can be predicted or avoided.
Any questions regarding a particular SyncroFlo pump station can be addressed by calling (770) 447-4443, and supplying us with the system’s production number which can be found in several locations on or in the pump station and control panel.
