Hello All.
I have a Hotsy unit with a Hawke pump. Its a 1270SS model with 4000PSI and 4.5GPM. It sucks from a 325 gallon tank. The tank is in the middle of the trailer with 8 feet of hose going to the pump. I used to have a inverted U shape valve assy. to divert the suction from the float tank to the large tank and vice versa. I experienced pulsation and low pressure with this setup. Took it to Hotsy sales rep and he replaced seals and said lose the valve assy. I now route right from the big tank through a brand new screen filter to the pump. There is still 8 feet of 3/4 hose feeding the pump and the rise from the floor of the trailer is about 2 feet. I can attain only 3200psi with the gun running. The gauge is 20 feet from the pump right before the hose reel. I still have pulsation as well. I have been told that turning the machine around which will shorten the supply hose by 3 feet will fix it. I don't see how. The unit has only about 35 hours on it with the seal overhaul at 8 hours. I think my pump has issues but don't know what. I bought a new seal kit and am going to learn to inspect the pump seals and ceramics to do my own maintenance. I am very mechanically friendly and doing so doesn't worry me. I pulled the brass caps off the pump and don't see any seals. Do I have to pull the entire pump head? If so, will oil come out? I haven't messed with the unloader and the suction line for soap is always closed tight.
This unit is frustrating me beyond words. Any help would be greatly appreciated.
