The APG pumps are submersible pumps with a horizontal discharge port. They are specifically designed for the pressurised pumping of sewage and wastewater containing destructible solids. The pumps are equipped with a cutter system which cuts destructible solids into small pieces so that they can be led away through pipes of a relatively small diameter. The pumps are available with or without control box and level switch. Pumps without control box must be connected to a separate pump controller with motor starter.
The compact design makes these pumps suitable for both temporary and permanent installation. They are suitable for both free-standing installation and installation by means of an auto-coupling guide rail system. The APG pumps are designed for pumping:
- Wastewater with high content of fibrous material

Recommended spare parts
Even though the Grundfos strategy is to supply the best possible pump solutions to our customers, after a long period of operation there will be wear and tear to some of the components in certain situations. If short operating downtime is a requirement, or if the pump is installed in inaccessible areas where delivery of spare parts may take a long time, it is advisable to maintain a small stock of recommended spare parts on site.
Please contact your local Grundfos company to obtain information about recommended spare parts or service kits for your Grundfos product.
Repair and maintenance
Grundfos Service will maintain and repair your pumps. Our service professionals can also advise you on efficiency issues, offering suggestions for saving money in the long term.
Repair and maintenance of your existing pump systems
Naturally, you can always call Grundfos for the repair and maintenance of pumps you have purchased from us. Grundfos can repair your pumps to the same specifications as new. However, 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. Working in collaboration with our local authorised service partners we offer worldwide service. Help from qualified pump professionals is never far away, whether you need immediate assistance or are interested in hearing about opportunities for making savings.
The Grundfos Pump Audit is our replacement analysis. It is a complete diagnostic tool that considers your facility, the energy efficiency of your system, and the total life-cycle costs of your pumping solution. It provides detailed recommendations for replacement, including estimated payback time.
Let our Pump Audit tell you how to save on energy costs
The Grundfos Pump Audit is a comprehensive check-up of your pump system. It measures flow, pressure, power absorbed, and overall efficiency of the pumps you have installed over a given period, and highlights how much energy you could save by switching to more efficient pumps and motors.
The process starts with the Pump Audit team visiting your facility and listening to your description of your requirements, with the aim of ensuring the best possible definition of the task ahead. The next step is a comprehensive on-site visual inspection of your facility. This includes inspection of the operating environment, pumps, valves and line drawings.
The purpose of CAPS is to provide a complete tool that contains both an extensive catalogue of Grundfos products and a sizing program to select the most suitable pump for your application.
There is also a comprehensive pump replacement selection function for central heating circulator pumps, hot water pumps and wastewater S pumps, and a function for producing professional quotations that include curves, drawings, quotation texts, wiring diagrams, etc.
Last but not least, the software contains the instruction and operating manuals for nearly all Grundfos pumps 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, available on CD-ROM, and the online version WebCAPS, available at the Grundfos website. Additional features available in WebCAPS include CAD Drawings and Literature.
"BE Responsible" is one of our core values at Grundfos. It is essential to us that our pumps are designed for low energy consumption and the highest possible performance throughout their operating lives. One consequence of this is that service offerings, including spare parts and replacement kits, are defined in the development phase.
Customised service offerings, online ordering and rapid response distribution centres ensure that you have the parts when you need them.
