The problem is the distribution plate. The plate is made to accept only Bykski pumps, and the interface between the pump and plate is by o-rings. If you tried to use the EK pump, you would have no way of connecting it to the distro plate.
If you think the pump is the problem you can try replacing it with the same model. That would be relatively straight forward. You would have to drain the loop, swap the pump, reconnect the power and pwm cables, and refill the loop. There’s guides online for draining and filling loops. That’s likely your best bet.
To me, it doesn’t look realistic.
