Hand pump version 2
We have optimized the hand pump over the past few years. The weak points of the old pump, especially the gray cover, were eliminated and replaced by own productions. The improvements to the original version of the pump are:
- New T-handle : The old D-grip was stable, but somehow it was too clunky and too small for us, especially with gloves. We have chosen the new grip for a T-grip, because it is easy to grip. Our T-handle is not an accessory, but we have the shape and make the handle exclusively for ourselves. The material is PA6 and should yield only in extreme extreme situations.
- New cover : The gray cover of the original version could not always convince with cold. Many customers got replacement because the lid was cracked. We have therefore designed a new lid, which is not only much more solid than the old one, but also reliably seals the pump and delivers the air (or even remnants of water) cleanly through the defined outlet. Anyone who still turns the outlet away from himself will remain dry! The lid is also made of PA6 and very solid. The guidance of the drawbar has been improved and the pump is no longer "rattling", quite in contrast to some competing products.
- New NBR piston : The previous piston was a purchased part and made of PVC. In the long run, however, we could not convince ourselves of this and with our manufacturer we have done a lot with a new piston made of durable NBR rubber. The result convinced even critical Swiss gold washers immediately! The piston seals very well, but also tolerates foreign bodies in the sealing lip, which is designed as a double head, which was inspired by concrete pumps. The piston is the only wear part of the pump, which is why we have placed special value on a favorable price
- Knurled drawbar : This customer tip was taken over by us enthusiastically. The pull rod is now provided with a knurl, which forms the seat of the pistons. Together with a rust-free hose clamp (W4), the fixed seat of the piston is now secured in every position! Another example where customer requirements have been quickly incorporated into the product.
- Double piston pump : This idea also came from a customer and was taken over as an option. Instead of a piston, two pistons are located one behind the other on the drawbar. The trick is that: if sand gets into the seal of the first piston, the second piston still seals. That both pistons are open at the same time by sand is more than unlikely. The result is impressive: the pump has a strong suit in every situation. Even cold can hardly affect the NBR double piston. I myself wash since introduction only with the Doppelkolbenpumpe. For the conversion to a hand- and sandpump the double piston is obligatory!
- All metal parts made of aluminum or stainless steel : The stainless steel prices have been falling for years and we have used this price reduction to replace all normalities (screws, nuts, etc.) made of stainless steel. This means you have a lot of fun with your product and we have the good feeling to offer an optimal solution.
- Silicone lubrication: All pumps are lubricated with silicone spray when installed. Silicone spray keeps the piston lubricated for a long time and has to be lubricated only at long intervals.
The assembly of a double piston pump can be seen here. In addition, the second piston improves the guiding of the drawbar, the work is much more precise and easier. The double piston is an option and must be selected separately.
The HT adapter opens the world to use commercially available HT pipes with a nominal diameter of 50mm, which can be found in any hardware store. Now everyone can build and attach "his" special nozzle at favorable prices. Also the T-collector needs a HT adapter, which is always the same in the T-collector set!
The T-collector is plugged onto the pump by means of an HT adapter. With it, it is possible to make several pump strokes at one point before the pump has to be emptied. The material reaches the T-piece when it slides back and is collected in the closed end. I make 2-4 strokes before I drain.
And here is a short guide about working with the pump and its maintenance and cleaning.
