Basics

This piston is a complete new development and differs in many respects from the previous standard piston. It is made of NBR with 60 shore in contrast to the former PVC piston. As a result, the wear characteristics are noticeably improved! Moreover, the seal is such that much less sand can migrate through the piston and damage it. The shaft was extended once more to ensure even better adhesion.

Variant of double piston

If you work with the sandpump, you can apply additional pressure to the piston. In order to increase the seal and to reduce the wear, the following variant can be selected: Two pistons are used in succession (option: double pack! 40% discount on the second piston!), The rear of which has been drilled on the base ( 16mm drill bit). In our picture, the two hose clips are missing, which fix the two pistons on the drawbar. This should be prepared for the heavy duty.

Description of options

For the construction of a twin piston pump, one of the pistons must be provided with a bore of 16mm. Since this is a quite big drill, we offer to drill the piston. It is possible to select whether no one, one or both pistons (when a double pack is ordered via the double pack option) are to be drilled.

In addition, one (or two for the double pack) Stainless steel hose clamp can be ordered. This is especially interesting for the double piston version or for those who still have the older split version of the piston. During assembly, ensure that the hose clips are properly seated! These small hose clamps are prone to the stiffness of the pull threads. One think, the clamp sits, it rubs only (here is the stainless steel also a small disadvantage). Perfectionists lubricate the thread with sth fat, that should help! I can only recommend the use of hose clamps. If these are installed properly, there is nothing better.

The double-pack piston makes sense to everyone, then you have a spare part at a low price (40% discount on the second piston!). Mandatory for all who want to mount a "fresh" double piston!

Comments:

We recommend to check the piston once a season and change it if necessary (of course not if the part was only in the cabinet) ;-) When reassembled, the pump wall can be lubricated with a lubricant (eg PFTE / Teflon or Silicone spray) or an acid-free oil (creep: Balistol!) Are lubricated. In addition, it is not a mistake if the inner wall is freed from the coarsest scratches with a 240 sanding paper! The piston thanks to it!
