If the Calpeda Water Pump motor doesn't start, first ensure the mains frequency and voltage match the electrical characteristics on the indicator plate. If the power supply is correct, check for and remove any shaft blockages. If these steps don't resolve the issue, the engine may need repair or replacement.
What to do if Calpeda Water Pump runs but no water comes out?
If your Calpeda Water Pump is running but not pumping water, examine the suction tube connections, drain plugs, pump filling points, and suction pipe gaskets for air leaks and seal any loose connections. Also, inspect the foot valve for blockages and ensure the suction pipe is fully submerged in the liquid. Clean or replace the bottom valve and use a suitable suction pipe. Check the suction filter and clean or replace it if blocked. Finally, verify the integrated non-return valve is functioning correctly.
How to improve Calpeda Water Pump flow?
If you're experiencing insufficient flow with your Calpeda Water Pump, start by checking if the pipes and accessories are adequately sized to prevent excessive head loss; use suitable pipes and accessories for your application. Next, inspect the rotor for deposits or solid bodies and clean it; install a suction filter to prevent future blockages. If the rotor is deteriorated, replace it. Ensure that the viscosity of the liquid isn't too high. Reduce the suction head if it's excessive. Shorten the suction pipe or use a wider diameter pipe.
What to do if my Calpeda Water Pump does not stop running?
If your Calpeda Water Pump won't stop, check the integrated check valve for any blockages or solid parts and remove them. Also, review the UP01 parameter for the stop pressure and reduce it if it's too high.
Why is my Calpeda Water Pump making noise and vibrating?
If your Calpeda Water Pump is producing excessive noise and vibrations, first check the rotor for obstructions. If there are no obstructions, inspect the bearings for wear and replace them if necessary. Ensure the pump and pipes are firmly attached. If the flow is too strong for the delivery pipe, use larger diameter pipes or reduce the pump flow. If the pump is cavitating, reduce the flow and/or use pipes with a larger internal diameter.
How to unblock a Calpeda Water Pump?
To unblock a Calpeda Water Pump, if rust has formed due to inactivity, use a screwdriver to turn the notch on the back of the shaft after turning off the electricity. If solid bodies are present in the rotor, dismantle the pump casing and remove them. If the bearings are seized, replace them.
Why does my Calpeda Water Pump work intermittently?
If your Calpeda Water Pump is working intermittently, check the built-in check valve for proper function and remove any solid parts. Also, check the tank pressure.
Why is my Calpeda Water Pump leaking from the mechanical seal?
If there's leakage from the mechanical seal of your Calpeda Water Pump, and the seal has functioned dry, has been scored by abrasive parts, or is unsuitable for the application, replace it. Ensure the pump casing and suction pipe are full of liquid and air has been expelled. Install a suction filter and use a seal suited to the liquid being pumped. If there's a slight initial drip, wait for the seal to adjust.
What causes excessive starts per hour in a Calpeda Water Pump?
If your Calpeda Water Pump is starting too frequently, check the tank pressure and consider installing a higher capacity tank.
