Need a Pump for a Zodiac

We have a zodiac zoom inflatable dinghy.  We are trying to inflate it and we have a pump that does not seem to be working.  We are not sure if it is the pump or the values on the dinghy that are not working.  Does anyone have a pump for a zodiac that we could try out? I have a picture of the pump that we have if that might be helpful. 

Please email Genny Redman at gkredman@gmail.com or call 250-210-3087 if you think you might be able to help us out. Thanks so much!
