Basics

Since HT pipes tend to diverge axially when pressure is applied, a fixing must be made! We have developed this yoke clamp, which is made entirely of stainless steel, as well as all attachments. The yoke clamp sits on the pump side behind the HT adapter, which is secured with a hose clamp before the slipping (HT-adapter possibly underlay with armor tape!). On the HT flange side, the clamp is simply pushed onto the HT tube at any flange and holds everything tightly together.

The screws are only tightened by hand. They should only keep the tubes apart from each other, do not wedge the tubes together (this is not necessary).

Concept of the Goldblitz Sandpump

Basically, it is a matter of pumping finer material directly from the stream into a container or into a channel, using a continuous process. In contrast to this, in the normal use of the pump it is always worked in two steps: suction and emptying. The sand pump is omitted from the step "emptying" by the fact that the sucked-in material is conveyed into a container or a washing trough by means of a valve system. Pumps such as this are e.g. Under the product name "Gold'n'Sand" or "Gold and Sand". We have picked up this concept and thought it through. We call this concept "sandpump". This includes our hand pump, a T-collector and at least 2 valves for 50mm HT pipes. Optionally, a hose guide in two different diameters can also be connected in order to pump the pumped material into a distant container or a washing trough.

Here are the features and advantages of our system "Sandpumpe":

• Maximum delivery is 37mm in the narrowest diameter. Filters with 15mm (coarse filter) and 8mm (fine filter) can be installed.
• Simple valve technology reduces jamming and can be repaired anywhere in the world (e.g., bicycle hose, tarp, plastic piece, etc.)
• Very affordable price through optimal integration into existing systems and techniques.
• With 4-valve technology practically no more jamming.
• By expanding with 50mm or 32mm tubing, the material can be pumped into a distant bucket or chute.
• Stainless steel screws.
• Also suitable as a bilge pump.

In the case of a system consisting of one valve each on the suction side and the pressure side, sharp-edged stones with unfavorable geometries (long and narrow) must remain stuck in the valve and obstruct the function at the following stroke. In order to remedy this, we offer a 4-valve system, optionally with maintenance flap. Although a valve can just as easily jam, another valve connected in series ensures that the function is maintained. Pumping pleasure almost without downtime!

Comments:

The package is aimed at those who already have a T-collector and want to continue using it, but also for those who want to add further crafts after the hose.

To assemble the sand pump and change the valve covers, here is a instructions (ca.300kB )

The valve linings can be different than seen on the pictures! I refresh the pictures at times. The current seals are smooth on both sides, 3mm thick and have a fabric insert.
