Cooling of double mechanical seals
Thread Content
A newly purchased pump with double mechanical seals cannot provide corresponding cooling because there is no cooling water on site. Do you have any other ways to provide cooling?
Clean. The medium is hydrogen peroxide. No impurities.
Shandong Double Wheel Emco pump? What does the manufacturer say?
Otherwise, you can dismantle the pump, remove the set of seals at the pump end, keep the outer set, plug one hole, and connect the other hole with a pipe from the outlet. If the head is high, add an orifice plate to limit the flow. The premise for this change is that the subsequent sealing can withstand medium corrosion.
Is the secondary seal cooled by water circulation? Wouldn't it be enough to just set up a tank? What is the medium temperature?
It looks like a single end face with a self-flushing and an external cooling water
I want to change it to the one shown in the picture. Use its medium for cooling. Please see if it is feasible.
Connect a flow-restricting orifice plate or valve to the pipe returning to the inlet, and connect a pressure gauge in front of the orifice plate. Ensure that the return pressure is higher than the inlet pressure to prevent the mechanical seal from being pushed open due to back pressure.

Can you provide the working condition parameters and mechanical seal structure diagram?
