Head Pumping

On my 34 Californian I have a Sealand diaphragm pump that pumps wast over the side through a through hull fitting. If I close the through hull fitting the pump will divert wast to the deck fitting. There is about four feet from the holding tank and the deck fitting.

Question If I close the through hull, open the deck fitting incert the pump a head nozzel, turn on the pump a head and then turn on the Sealand pump for extra boost to get wast to the deck fitting will the suction of the pump a head damage the diaphragm of the Sealand pump.
