Additional Information:
My pump has been installed for almost a year. When the boiler is first brought up the pump starts working and pumps fine most of the time. Occasionally the pump will just click and they have to stop & start again and again until it kicks in. What could be causing this?

A:
Check steam traps and check valves to insure they are functioning properly. Secondly, the water in the return tank could be too hot. Make sure that the float valve inside the tank is working properly and allowing cold water in. Make sure that the check valves closest to the boiler are not leaking and allowing hot water to seep back into the return line and thus back to the pump. Hot water cannot pump against the high boiler pressure so the pump manufacturer recommends temperature should not exceed 180 degrees for best pump performance.

I have the 1 ½ HP pump installed for approximately 2 months and it keeps shutting on/off and is running very hot. I have checked the strainer, float valve and check valves for problems but everything seems fine. What else can I check?

A:
Based on these symptoms the most obvious part of your system to check is your steam traps. The water is most likely much too hot indicating a defective steam trap.

Can I upgrade my pump from ½ HP to ¾ HP?

A:
The pumps are physically the same but you do need to check the amperage draw. The ½ HP at full load 115V draws 8.8 amps / 230V 4.4 amps. The ¾ HP at full load 115V draws 10.6 amps / 230V 5.3 amps.

Can a pump be tested prior to installation to make sure it runs before it is plumbed in?

A:
Pumps should never by pre-wired to the electrical source and run dry. It will destroy the mechanical seal or burn the packing material and therefore void the manufacturers warranty.

If my pump is leaking do I replace the seal or the o-ring?

A:
It would depend upon where the pump is leaking from. If the pump is leaking at the seam between the impeller and raceway, you will need a new O-Ring. It’s leaking towards the shaft, you will need a new pump seal.

What does it mean when a pump “Cavitates”?
Anonymous

Please Note: Your answer will be displayed upon approval.
A:
Cavitation implies cavities or holes in the fluid we are pumping. These holes can also be described as bubbles, so cavitation is really about the formation of bubbles and their collapse. Bubbles form whenever liquid boils. Therefore the capacity of the pump is reduced. This happens because bubbles take up space and you cannot have bubbles and liquid in the same place at the same time. If the bubble gets big enough at the eye of the impeller, the pump will lose its suction and will require priming. Cavitation can be the noise you hear coming from your pump. Pump parts can show damage because the bubbles “implode” and the force of the fluid actually bangs the bubble against any metal surface causing damage.

Do the Single Phase pumps have built in protections against lightning strikes or power surges?

A:
The manufacturer advised that these pumps have a Thermal Protection that will shut the pump off if it reaches a certain temperature, but no power surge protection. The customer is required to provide this sort of protection.

Why would my Turbine Pump loose its prime overnight?
Anonymous
Posting As
Please Note: Your answer will be displayed upon approval.
A:
There could be a few reasons. Check the check valve between the pump and the boiler to make sure it’s clean and operating properly. Check the steam trap- and make sure they are not blowing steam. Make sure the strainer isn’t plugged up. Is the float valve operating properly? Water needs to be mixing with the return tank water. If this is an old pump, make sure the impeller is adjusted, and if worn out, replaced.

We have installed our new pump according to the manufacturers’ directions but our pump still will not come on, what did we miss?

A:
Check the safety latch on your boiler door. If this feature is malfunctioning it will not allow the pump to start.

I just installed my new pump, and the shaft is not turning, what is the problem?
Anonymous

Please Note: Your answer will be displayed upon approval.
A:
It is very difficult to turn the shaft by hand, it would need to be hooked up electrically. I f the pump is not wired in properly, then the shaft will not turn. Some are preset at 230 volts, please make sure that the preset voltage suits your needs, otherwise, follow the wiring diagram on the side of the pump to adjust it.
