Pump station DORANT

Features

Resistant

The plastic PE-HD is corrosion-resistant to gases and reliably resistant to chemical components in wastewater. The smooth inner surface prevents deposits.

Easy discharge

The fully equipped pumping station is delivered to the construction site in one piece and lifted directly from the truck into the excavation pit.

Buoyancy protection

Depending on the requirements, buoyancy protection is already firmly welded to the structure by the manufacturer - in the form of an enlarged cantilever plate made of PE-HD with a steel-reinforced concrete core.

Armatures

Kordes armatures score with particularly unbreakable materials and a low-maintenance design with few assembly and fastening elements.

Lightweight

The lightweight Dorant variants are particularly easy to transport and can therefore be used in difficult-to-access terrain.

Demanding areas of application

The Dorant pump station is also suitable for water protection areas, as the tank is of double-walled design and can be equipped with permanent leakage monitoring on request.

Application

Wastewater pump stations for municipal and industrial use

Wastewater pump stations in wet installation are ideally suited for municipal and industrial wastewater, as well as surface water.

Particular loads on the pump stations in the communal area are caused by heavy rain, digester gases, fats and fibrous materials. In the case of industrial waste water, there are aggressive chemical loads due to the ingredients. In addition to heavy rain events, areas of application for surface runoff from parking lots and streets also have the problem of increased salinity.

In each individual case, the pumping station must be dimensioned and configured in such a way that sufficient resistance for permanent use can be guaranteed. Due to the location, static safety against uplift in the presence of groundwater is often required for the shaft structure. Our ready-to-assemble pump stations minimize construction time. This significantly reduces costs for groundwater management and wastewater discharge, as well as traffic congestion during the construction phase.

Planning

Customized and individually designed

A frequently requested service from our company is planning support. The focus here is on the planning of wastewater pump stations, including the calculation of pumps, calculation of pressure pipelines up to the planning of pressure pipe flushing stations. The planning of EMSR and control technology are also among our strengths.

When you place your order, you will receive a detailed 2D and 3D drawing from us for your building project. This serves to visualize your new pumping station and facilitates technical optimization before the start of construction. Only when everything is perfect do we start production.

PE-HD

What is so special about PE-HD?

High density polyethylene (PE-HD) is a versatile plastic. This material is one of the most widely used in the field of industrial and municipal wastewater.

Thanks to its organic composition of only carbon and hydrogen, through which no toxic ingredients can diffuse out, PE stands for sustainability and an excellent environmental balance.

The anti-adhesive inner surface (k<0.05mm) prevents deposits on the shaft wall<0,05mm)

Installation

The pump station is placed in one piece within a few hours

Safe against buoyancy and ready for operation more quickly, even with high groundwater levels

The concrete cover is placed on the shaft pipe by means of a sealing ring

Cover plate made of PE-HD with steel-tested concrete core firmly welded to the casing pipe

Exposed concrete susceptible to corrosion if no covering is made at the construction site

Bottom side and dome entrance completely lined with HD-PE

Assembly and age-related leaks are to be expected

The cover plate is firmly and tightly welded to the shaft casing pipe

On-site concreting of a load transfer ring is necessary according to requirements

The load is transferred from the cover plate directly to the shaft casing pipe

Base plate in PE-HD

PE-HD base plate with steel-reinforced concrete core

Groundwater-induced bulging causes stresses and vibrations in the armatures

Stresses and vibrations are excluded from the concrete and PE-HD due to the special Kordes connection system

A foundation plate must be concreted on site, on which the PE-HD shaft is placed.

If buoyancy protection is required, this must be separately provided using a concrete bed

According to the requirements, the buoyancy protection is already welded at the factory as a cantilevered base plate

Pumps

For optimum flow rate and flow velocity, armatures, pressure lines and pumps must be precisely matched to the requirements of your construction site. Our product range extends from pumps with cutting impeller system for small wastewater volumes with admixtures, to pumps with free-flow impeller system. Both variants are available with and without explosion protection. For certain types of wastewater, pumps with special resistance to corrosive substances are also required.

Do not leave the right selection of your pump to chance and let us support you in the correct design. So that we can offer you the pump that is best suited for your construction site, we work together with the leading manufacturers of wastewater pumps. Our valve system can be combined with almost all common pumps with DIN flange.

Control units

With our Kordes control systems, we are able to switch single, double or multiple plants. Our control systems are used by commercial and municipal plant operators and can be customized with electronic components on request. In the field of municipal wastewater discharge, we also supply PLC-controlled systems as well as process visualization and telecontrol technology. We will also be pleased to supply you with the appropriate control unit for your project. In the factory, the control system and the desired components are already installed and tested in the control unit according to your specifications.

Accessories

Access ladder

Pump stations require a safe access ladder. For this purpose, we build stainless steel ladders with safety steps in widths of 300mm and 400mm. The pull-out boarding aid provides safety when entering. For deeper pumps stations we offer a fall protection system or an intermediate ceiling according to UVV.

Pipe lead-through

For a tight connection between the shaft and the pipe, we offer Kordes ConFix feed-through systems. They form a permanently elastic, tight connection between the pipe and the concrete or PE-HD wall. Pipes made of cast iron, steel and plastic are sealed gas- and watertight in core drill holes or lining pipes by pressing together an NBR rubber ring by means of two V2A stainless steel flanges.

Plug-in gate valve and spindle gate valve

In the case of pumping stations, it is sometimes desirable to be able to shut off the supply lines for work in the shaft. For this we offer plug-in or spindle gate valves for the appropriate pipe diameter. It is operated mechanically or by an electric drive. The controller can be connected to the BMS.

Shaft ventilation

Appropriate stainless steel or PE-HD piping should be installed in the shaft for ventilation. For the end of the underground pipeline we offer ventilation chimneys made of stainless steel in DN 100 / DN 150. The stainless steel cover can be equipped with vapor hood on request.

Covers

We offer shaft covers depending on your requirements in square or round shape as BEGU, in cast iron or stainless steel. The shaft system corresponds to the load class SLW 60, so that shaft covers from class A to D can be freely selected.

Armature shaft

Armatures are usually located in the pump station but some operators prefer the armatures in a separate shaft, which we offer as a prefabricated part in PE-HD or reinforced concrete. The inductive volume measuring device or ventilation valves are also often installed in separate shafts.

Technical building

Optionally we offer a suitable technical building for your pump station. We arrange the equipment individually with you in order to find an ideal solution for later operational management.
