Why is there insufficient flow from my Calpeda CT61?
- R
  Richard CastilloAug 16, 2025
  Insufficient flow from your Calpeda Water Pump can stem from several issues. Start by checking if the pipes and accessories have a diameter too small, causing excessive head loss; if so, use appropriately sized pipes. Also, inspect the rotor for deposits or solid bodies blocking internal passages; clean the rotor and install a suction filter. Check the rotor and pump casing for wear, and replace them if necessary. Ensure the liquid's viscosity isn't too high for the pump, and verify the pump's rotation direction is correct by checking the electrical connections. Reduce suction head if it's excessive, and shorten the suction pipe or use a wider diameter pipe if it's too long.

How to reduce noise and vibrations from my Calpeda Water Pump?
- K
  Kyle ButlerAug 21, 2025
  To reduce noise and vibrations from your Calpeda Water Pump, start by checking if any solid objects are obstructing the rotor. Inspect the bearings for wear and replace them if needed. Ensure the pump and pipes are firmly attached, anchoring the delivery and suction piping as necessary. If the flow is too strong for the delivery pipe's diameter, use larger diameters or reduce the pump flow. If the pump is functioning in cavitation, reduce the flow by adjusting the feeder gate and/or using pipes with a bigger internal diameter. Verify the mains voltage is correct, and if necessary, realign the pump-motor unit.

What to do if my Calpeda CT61 functions but no water comes out?
- I
  ithompsonAug 27, 2025
  If your Calpeda Water Pump is running but not pumping water, first check for air infiltration from suction tube connections, drain plugs, the pump filling point, or suction pipe gaskets; tighten any loose connections. Next, inspect the foot valve for blockages or ensure the suction pipe is fully immersed in the liquid; clean or replace the valve and use a suitable suction pipe. Finally, check the suction filter for blockages; clean or replace it if necessary.

Why is my Calpeda CT61 leaking from the mechanical seal?
- D
  Diana GonzalezSep 3, 2025
  Leakage from the mechanical seal of your Calpeda Water Pump can occur for several reasons. The mechanical seal may have functioned when dry or has stuck. The mechanical seal could be scored by abrasive particles in the pumped liquid. The mechanical seal might be unsuitable for the application. If any of these issues are the cause, replace the seal. If the leakage is a slight initial drip during filling or on first start-up, allow time for the seal to adjust to the shaft's rotation. If the problem persists, consider the other potential issues.
