Overview

Grundfos offers a wide range of dosing pumps representing state-of-the-art technology.

Digital Dosing solutions (SMART Digital, DME, DDI) set new standards in liquid chemical handling and accuracy. The operator can easily install and set up the pump to discharge exactly the quantity of dosing liquid required for the process in a unique drive- and flow-control management concept. The setting of the pump is displayed in ml/h, l/h or gph, and the operation mode is easily identified by means of icons.

The DMH mechanical hydraulic dosing pump range is the preferred choice for industrial and complex tasks. The DMH range is a series of extremely strong, robust pumps for applications where a substantial dosing range and high-pressure capabilities are required.

Installation

Commissioning

To achieve optimum performance and operating condition it is very important that the Product/System is set up and adjusted correctly from the start. The knowledge from the Grundfos Service technician and the use of Grundfos specific service tools to adjust the performance of the pump guarantee that the customer can be sure that that the highest efficiency and proper operation is achieved. Commissioning of the pump is recommended for the following applications:

  • If the pumps are controlled by a frequency converter .
  • If the pump system is operating in large systems e.g. Building Management Systems.
  • If the user wants to be trained in proper operation of the pump.
  • If the pump must not be a missing link in an important production/application facility.
  • Where the setup is crucial for proper life of the Grundfos product, e.g. water treatment applications, commissioning is not only recommended but it is required.
  • Where safety is an issue e.g. disinfection system.


The commissioning is performed in a step by step procedure and the outcome will be a report of the settings of the pump.
Do not hesitate to contact your local Grundfos company to arrange commissioning of you new installed Grundfos product.

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 information about recommended spare parts or service kits for your Grundfos product.


Operation

A Grundfos Service Agreement ensures efficient and uninterrupted operation of your pump 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.

You simply combine a range of service to suit your needs – and let us carry out scheduled maintenance visits to prevent downtime. We offer three types of Service Agreements available for all pumps:

  • Basic
  • Extended
  • Total.


Whichever you choose, 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 at a minimum, because our careful consideration of the Life- Cycle Cost of all our products means that we have control over 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 ensure 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

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.


Replacement

CAPS

The purpose of CAPS is to offer a complete tool that contains an extensive catalogue of Grundfos products and a sizing programme to select the most suitable pump for your application.

On top of that there is a comprehensive pump replacement function for central heating circulating, hot water pumps and the wastewater S pumps and the possibility of producing professional quotations including curves, drawings, quotation texts, wiring diagrams etc.
It is possible to export all this in the most popular file formats including gif, bmp, txt, dxf, etc.

Last but not least the programme contains the instruction and operating manuals for nearly all pumps of Grundfos in multiple languages. Service drawings, exploded views and parts lists are available for all sewage products as well as several other pump types.

CAPS is available in two versions: WinCAPS is available on a CD-ROM and the online version called WebCAPS is available at the Grundfos website. Additional features in WebCAPS include CAD Drawings and Literature.
