The effect of seal flushing on pump flow rate
Thread Content
For self-priming pumps, if the seal flushing pipe is too thick and thus results in a high flushing volume, will this have an impact on the pump’s flow rate and outlet pressure? Is the low flow rate caused by insufficient pump pressure?
No, you’re overthinking it; the amount of water used for rinsing is very small
That won’t happen. The flushing of the mechanical seal serves mainly to cool it, and it does not come into contact with the medium being transported
It is best to have a orifice plate for self-flushing
It is necessary to consider the location where pressure is taken and the pressure difference in the sealing chamber; when the pressure difference is small, the flow rate will not be high. For situations with a large pressure difference, flow-limiting orifice plates are used; domestic companies generally employ flow-limiting pipe fittings. The aperture is small and the flow rate is low, so there’s no need to worry about it.
It’s such a small root canal – the exit opening is big enough, so it won’t cause any problems
No, it has no impact; it’s possible that it will increase the pressure in the pump
