Inquiry (采购产品): trouble with my tonkaflo 5500 pump I operate a recycling plant. We process antifreeze. I have a Tonkaflo 5500 pump on a 25 HP electric motor. I am not getting any pressure to buiuld up in the system. Flow rate of 55 GPM goes to almost 0 when any pressure is applied. What steps would I take to get the pump checked? **** Hidden Message ***** Jerry Stumpf 16601 Company: On The Spot Recycling E-mail: jstumpf@atlanticbb.net **** Hidden Message ***** jstumpf@atlanticbb.net
