What type of pump is it?
If it is a metering pump, it's likely you have to provide a pressure sustaining valve on the discharge side to stop the siphoning effect.
If it is a centrifugal pump, the pump may provide more head than required. This would make the pump curve too high. The high flow rate at this head would cause damage to the pump, so it may be the case the pump has some kind of safety shut off. Throttling produces more frictional losses, pushing the system curve higher. The flow rate at this level is healthy.
