I didn't realize that the new pumps have the pressure switch set extremely high. My guys had been using the Everflo and we had to keep them turned up high to get distance and we had usually kept throttle valve closed and that it would shut off. We can't do this with the new pumps. If you keep throttle valve closed you will create a leak at a seal on a banjo valve, or bust a seal. I'm not sure if this is mentioned to companies that might buy this pump and don't use a rig with a throttle valve.
So there is no pressure switch on the pump? What pump is it?
No there is a pressure switch. The new pumps are WAY more robust and come with the pressure cut off at 110 psi. We are actually playing with setting the pumps to cut off at 85 psi and the injection pump to cut off at 60 psi and running the system in demand mode. However the 7 gpm may be too big for that.
All of our new SoftWash Systems branded pumps are sold through our distributors as well as you can call the office directly. We did send out an e-mail blast back in November and ran a special program on these to introduce them and make a little pay-up for the everflow disaster.
We have these new SWS pumps in 2.5, 3, 5.5 and 7 gpm sizes.

Hello All, I just replaced my last EF7000 pump (lasted 2 months) with the new Softwash Systems branded 7 gal pump and have another on the way as the backup. I too see almost 120 psi when the pump is at pressure with the throttle closed. Sure is quiet, and more robust. Looking forward to a quality pump on board!
1. Any feedback out there on performance, issues, over heating if used with the throttle open for less pressure and continuous run?
2. I don't see an accessible fuse or relay as was on the EF7000. I went through numerous fuses and 3 relays on the 7000. Do I need to stock up and carry spares of any items like that?
3. Is there a pressure switch adjustment screw to tweak the pressure down some?
thanks in advance, and hope all are busy
V/r Jeff

I had one pump die after a couple of days, but it turned out the relay was bad. I replaced and haven't had any problems since. You should buy a couple of relays to have on hand. We let the pump run continuous and just use throttle valve to lower pressure.
I had many relays go out, and was working with David a lot for a couple weeks trying to solve the problem. Eventually, after about 4-5 relays, the pumps failed completely, and we decided to try the 5.5gpm pump. It has no relay, but does have a pressure switch, and pulls less amps. My system has worked fine ever since. There is no change in spray distance or volume, transferring chems takes a little bit longer, but hardly noticeable. My advice would be if you go through more than a couple relays, send back your 7gpm and get a 5.5gpm. The added bonus is that you get longer running time out of your batteries as well due to the lower amperage.
Watch your bypass valve very closely, especially during the break-in of this new pump. I think this pump has more tendency for the pressure to creep up as it warms up/ breaks in. I think this may have been some but not all of my problem.

I have noticed the creep factor with our new pump as well Chad. I actually called and spoke to David about it just to make sure that our pump was good. He reiterated not to let it creep above 70 psi in bypass. I've been starting the day at 55 psi in bypass and within a few minutes it will creep up to 70. Once it's warmed up it sits right on 70 all day.
