Hi all thanks for the advice. I really tightened up the pulley belt and it no longer slips and now pumps regularly. The only slight concern is that the piston rod camshaft part sitting in the splash oil bath gets hot enough eventually to remove your hand. Hopefully it too loosens up in its bearings. I might run a by-pass water drip over it

Hello again. I loosened the nut but it made little difference. My conclusion is that because the diameter of the drive motor pulley is so small - in order to get the motor speed reduced and restrict the piston action to a safe recommended speed - there is insufficient contact area or friction to turn the tight pump pulley. So it spins. I am going to use a larger twin V drive pulley to increase the contact. And use a double V pump pulley. The only trouble with this solution is that it is quite costly. That's life. Thanks for the advice. Regards to all from the deep south of Western Australia. Brian

I'm not sure how to reply to respondents except this way, but thanks to David Baillie for replying with advice. Not sure which parts he refers to be loosened so the exploded view of the pump can be found at https://pompco.com/docs/048-0170-manuel-pompe-piston-s-s-5.5-x-8-2014.pdf

Thanks

Hello. Perhaps someone has experience with the Canadian Pompco horizontal piston pump. I bought the stainless model as the water is a bit salty. My problem is that the drive wheel is extremely tight and hard to rotate. The dealer said that he'd be worried if it wasn't tight and it will loosen up. But the electric drive motor simply spins its pulley without making the pulley belt turn. Everything is set up ok, but its clear the pump is tight. Is that normal? I'm in Australia not Canada and my emails have not been answered by the company. Thanks for any advice.
