DPK

Overview

Overview

DWK and DPK are submersible pumps designed for dewatering and drainage applications. The cast-iron construction and the hydraulic design contribute durability and high efficiency. The differences between the DWK and DPK pump ranges lie in the discharge arrangement and the installation type. The DWK is designed with a top discharge pipe and suction strainer, and is thus more suitable for temporary installation, whereas the DPK has a side discharge and a ring-stand or auto coupling (as accessories), and is suitable for permanent installations.

Applications

DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation. The installation design options provide the flexibility needed to cover many needs. Applications include:

  • Construction sites
  • Excavations
  • Tunnels
  • Fish ponds
  • Drainage pits.

Recommended Spare Parts

Even though the Grundfos strategy is to supply the best pump solutions for our customers, long operation will result in wear and tear of some of the components in the construction in specific situations. If a short operating downtime is a demand or if the pump is installed in inaccessible areas where delivery of service parts may take a long time, it is recommended to have a small stock of recommended service parts. Do not hesitate to contact your local Grundfos company to obtain advice about what is recommended for your specific application.

Optimisation

Grundfos offers an Efficiency Analysis of your existing pump system, providing you with suggestions for increasing efficiency, with cost savings over time.

Increase the efficiency of your existing system

Conducting an Efficiency Analysis of your existing pump system provides you with a basis for increasing efficiency, with cost savings over time. An Efficiency Analysis results in suggestions for doing this and will show how this will save you money.

Grundfos offers the following steps for analysing efficiency of your pump system:

  • Installed base checks


A minor evaluation is conducted based only on the data from the identification plate on the pump compared with the newer, more efficient technology and materials found in modern pumps.

  • Pump efficiency quick check


Pressure and kWh consumption of the pump are measured. Flow is estimated based on available pump data and the measured results.

Some of the resulting suggestions for improving efficiency are, for example, a speed control upgrade, a motor upgrade, differently dimensioned pipes, the installation of a controller, or perhaps an agreement for routine service.

Complete Pump Audit

The Efficiency Analysis offered by Grundfos comprises the first steps of our Pump Audit, a diagnostics tool that we use to clarify whether the pump system is energy optimized to guarantee that your costs are kept to an absolute minimum – now and in the future. See Replacement Analysis to find out more about Grundfos Pump Audit.

A Grundfos Service Agreement ensures efficient and uninterrupted operation of your pumps system and gives you access to Grundfos Service Centres and authorised Service Partners worldwide, 24 hours a day.

Prevention is better and more cost effective than cure

Once you have purchased your pump, you want it functioning efficiently and reliably, and a formal Service Agreement with Grundfos gives you peace of mind. It also makes sound economic sense, giving you a firm overview of your maintenance budget and access to substantial discounts.

Let us carry out scheduled maintenance visits to prevent downtime.

You will be serviced by specially trained staff at all times.

The cost-effective choice

Well-maintained pumps can reduce your energy consumption by up to 50% and in a series of pumps working together one faulty pump can affect all the others. A Grundfos Service Agreement keeps your total cost of owning a pump to a minimum, because our careful consideration of the Life- Cycle Cost of all our products means that we have control of the real costs of ownership of our pumps.

Signing up for a Service Agreement and letting our highly skilled service technicians service your pumps is your safeguard against unforeseen expenditure. Regular servicing and maintenance of your pumps ensures that they are working with optimum efficiency.

Grundfos Service will maintain and repair your pumps and our service professionals can advise you on efficiency issues, offering suggestions for saving money in the long term.

Repair and maintenance of your existing pumps system

Of course, you can always call Grundfos for repair and maintenance of pumps you have purchased from us. Grundfos can repair your pumps to the same specifications as new pumps, but it is important to remember that an upgrade or even a replacement pump can be cheaper than repair in the long term. See Upgrades and Replacement for how this makes good business sense.

Effective service – wherever you are

Grundfos Service is always close by. Together with our local authorised service partners, we offer worldwide service, and help from qualified pump professionals is never far away, whether you need immediate assistance or you are interested in hearing about your savings possibilities.

Grundfos Remote Management is a cost-effective, secure and reliable way to monitor and manage pump installations from an Internet PC at a very low price.

Connecting pumps and people

With a secure and reliable remote management system, you can monitor and manage your pump systems from an Internet PC at a very low price.

Grundfos Remote Management is a cost-effective and straightforward way to monitor and manage pump installations in commercial buildings and in water supply and wastewater infrastructure. It reduces the need for onsite inspections, and in the event of an alarm or warning, the relevant people are notified directly.

Compared with mobile phone-based monitoring, the system offers a wider range of benefits and functionalities. For those who do not require remote process automation, Grundfos Remote Management is the ideal solution for monitoring and remote control as opposed to traditional SCADA (Supervisory Control and Data Acquisition) systems. Initial investment is minimal, and a fixed low fee covers data traffic, hosting costs and system support, including back-up of all data.

Efficient alarm management

Via its on-call schedule, this new telemetry system ensures that alarms from onsite controllers go directly to the relevant people. From a PC anywhere, the system manager can log on and plan who is to receive alarm messages from each installation at any given time of the day. Managers can plan years ahead and easily handle daily exceptions to the schedule.

Optimize service and maintenance

Changes in pump performance can be tracked using trend graphs automatically generated by the system. This can give an indication of wear or damage in the installation, and service and maintenance can be planned accordingly.

The communication interface (the CIU27 modem) enables data transmission via GPRS/SMS from your Grundfos pumps and controllers. The built-in multi-purpose I/O board allows you to connect sensors and switches.
