Problem with vacuum tanker

[Bobthebuilder]

Have an old Abby 1100 gal tanker used for washing sheds/cattle pens and the odd bit of tank emptying, used it the other day and not sucking very well through 2” hose then when using on pressure side you could lay the pipe in ground and it wouldn’t thrash about like it used to so not much on the pressure side, will it be a seal issue or more likely to be worn vanes in vacuum pump? Is it an easy enough job to re vane pump?

What does the clock show? How much pressure and vacuum when you run it up. One thing that can easily catch one out is the inside of the pipes from the pump.to the tanker delaminating and the inners collapse during vacuum, but works find with pressure.

It’s not good both ways, didn’t look at the gauge to be honest

Easy job, have you flushed the pump out with diesel sometimes valves stick in the grooves used to put 10 litres through.

You've been together to long time to get rid and get a younger model

For what it does not really worth a younger model if a service kit will sort it

We once had the ball valve come to bits on us with similar symptoms

The empty/fill one

they do rust from the inside, have you checked for holes in the drum? Had the back open on ours the other day and I was really surprised at the amount of flaked rust in the bottom of the tank

Yeah the one in the pipe between pump and tank that gets sooked up when full to stop product getting to the pump it was an old tanker the ball was in a steel tube so you couldn't see it the newer ones usually have a clear bottom
