Construction work on our new building began in 2015. We had decided to plan a future-oriented pump room for our cooling water supply. However, we soon encoun­tered problems for which we had to come up with new solutions. It was partic­u­larly challenging that parts of the pipeline were laid under the founda­tions and therefore months before the pump room was removed. To cope with the limited space, we had to come up with a flexible solution. Thanks to the clever planning and hard work of our team, the pump room could be realized as planned. The result is impressive: The pump room is functional, easy to maintain and also future-proof thanks to the PE 100. Our customers also benefit from the newly found solutions to problems. Find out which solutions we have used:

Corrosion-free and reliable PE 100 flange connec­tions in the pump chamber

Our HP ME flange is the reliable loose flange connection with many advantages:

Our special flange VP was specially developed for connecting PE pipelines to pumps, fittings, butterfly valves and steel or GRP pipelines.

Config­urable PE 100 filters for the pump room

Our PE 100 filter is the best choice for you if you need a flexible filter. Thanks to the flexi­bility of our molded part production, we can configure the filter entirely according to your wishes. This means that the forward and return flow can be flexibly positioned in the configuration.

It is also easy to use, as the filter can be backwashed and opened using a practical quick-release fastener.

PE 100 pump transi­tions — flow-optimized, flexible or adjustable

The ideal pump transition is not only flow-optimized, but also offers flexible options for connecting measurement and control technology. This allows you to operate your pumps more effec­tively and save costs at the same time.

The Quick-Twist fitting and extension piece is a real break­through in pipeline construction. Thanks to the simple twist lock, it can be adjusted in an instant — without any threaded rods or fiddling around. The best thing about it: Quick-Twist is completely corrosion-free. So you can be sure that your pumps and valves will be perfectly maintained in the future.

Quick-Twist is ideally suited for connection to valves (gate valves, butterfly valves, MID, …) and pumps on both the suction and discharge side.

PE 100 floor bushing with power trans­mission and sealing — a clever solution for the pump room

Planning a PE 100 pipeline in the Riem Arcaden in Munich was a challenge. One question was how PE 100 pipelines can be routed verti­cally through floors and at the same time reliably transfer the forces into the structure. Together with the respon­sible planners, a PE 100 fixed point collar was developed especially for connection to buildings. The collar is designed to reliably transfer the forces between the PE 100 pipe and the wall or floor. In addition, a large-volume seal seals the core drill hole so that no water or dirt can penetrate. You can rely on our many years of experience and our service.

We like the solution so much that we also use it in our pump room. The water reservoir is located under the pump and the risers on the suction side are fixed to the floor with our PE 100 fixed point collar.

Incredible flexi­bility that provides planning security — PE 100 push-fit socket for a very special application

PE 100 inter­me­diate flange distributor — compact and flexible

The inter­me­diate flange T‑piece is a flexible and popular solution, especially where space is limited. The T‑pieces are connected via flanges and can be configured with different outlets. You can also decide whether the inter­me­diate flange T‑piece is configured with a weld end or threaded connection.

Even more flexi­bility: the inter­me­diate flange distributor offers you the oppor­tunity to bring even more flexi­bility to your instal­lation. You can set outlets during instal­lation or at a later date. The outlet positions are sealed with dummy plugs, which can be replaced by weld-on sockets. This allows you to set up to four outlets flexibly.

Pump rooms are often very confined spaces. The quality of the planning and choice of materials is crucial to whether the system will be successful in the long term or not. Pump rooms are often made of steel or stainless steel, although subse­quent pipelines are planned in PE 100 or PP. PE 100 and PP can be planned just as flexibly as steel/stainless steel pipes — with a few advan­tages to boot! Read here what is possible in PE 100 and PP and be inspired!

If you can’t get any further with standard molded parts: save space and costs and solve tricky problems with individual PE 100 molded parts

Are you reaching your planning limits? That doesn’t have to be the case! Our special molded parts made of PE 100 are the perfect solution for you. By combining T‑pieces, branches, dimension changes, measuring connec­tions and bends or elbows in one compact component, you can solve all your problems — and often in a single component. Our special molded parts made of PE 100 provide you with the perfect solution for your planning problems. By combining different elements in one component, you can get exactly the shape you need. Whether for welding in or flanging in, we will find the right solution.

Leakage and nominal diameter offset: the problems with standard plastic welding neck seals

The first plastic pipelines, PE (HD-PE) and PP, appeared and the connection dimen­sions were adapted for pre-welded joints of metal pipelines. However, this caused two problems: the internal offset between the plastic and the steel/cast iron/GRP pipe and fittings in particular, and insuf­fi­cient stability under many loads.

Reinert-Ritz has addressed these problems and today there are solutions to both problems: the special VP flange for the problem of internal misalignment and the HP flange for the problem of stability.

PE 100 and PP pressure pipes are used in many supply networks and indus­trial plants to transport liquids or gases. The pressure pipes are usually fitted with welding neck collars that are attached to metal flanges such as fittings. However, this design often has problems that can lead to leaks. The reason for the problems is that the internal diameters of many PE/PP pipe dimen­sions differ from the internal diameters of DN-oriented steel/cast iron or GRP pipes. As a simple solution, pre-welded collars are provided with a bevel on site. They are usually handled roughly with an angle grinder, which makes the collars unstable and can lead to leaks. To avoid these problems, it is important to select the right flanges at the planning stage.

Virtual flange finder

You can find out whether the special flange VP is the right choice for your appli­cation with our flange finder. Simply set the pipe diameter suitable for your appli­cation (e.g. DN/od 160) and read off to the left and right which DN/flange combi­nation fits best:

PE 100 / PP welding neck collars: When is the standard welding neck collar the right choice for your pressure pipe?

Designers and users of standard plastic welding neck seals know the problem. They are often difficult to seal during instal­lation. In addition, leaks often occur at flange connec­tions during the service life of the PE / PP pressure pipe. Some flange dimen­sions are easy to get tight, some require a lot of dexterity and others are highly critical. Pre-welded collars are not designed to be suitable for plastic, the plastic is overloaded and deforms over the course of its service life. The ambient condi­tions also influence the tightness of the connection — extreme cold or heat make instal­lation even more difficult. The result: expensive mainte­nance and repair work as well as production downtime.
