I just bought a Schwing P88, 2001 model with a Wisconsin motor. download free Isuzu Sitec 275 Service Manual. Rough but Cheap. Well i tried to use it on a on job for a test run. It'll pump and it will build pressure (evident when it made the hose bounce when we started) BUT IT WOULD NOT PUMP AT A HIGH VOLUME. JUST a little more than a TRICKEL OUT OF THE HOSE.

Im guessing that the springs are wore out but it confuses me because my macyo was a wore out and i know the springs were too and it always pumped adequate volume if it pumped at all.

ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED. What about the piston gasket or whatever its called. If that piston gasket on the crank side is worn enough that when it draws back its sucking air, water and oil from the wash box instead of pulling concrete into the cylinder.

Could that be enough to cause significant loss of pumping volume. Reason I ask is because when it is sitting i can see where small amounts of fluid have leaked into the cylinder from the wash box. All these issus seem like common ware issues which leads me to think it was the concrete.

I have a question on the Schwing P88. I am using it to pump ICF's.

My dad decided to start it up while it was open so the cylinders would push out anything inside or them. The largest cylinders case came forward along with pison. Now when we try to run it it seems to lock up and the arm on the second piston stays up in the air at times. When it does come down it comes down hard and it very noisy. I will see if I can add a video tomorrow to help. Mariner 30 Outboard Manual download free there.
