Conlift/Conlift L




The new Grundfos CONLIFT is a professional range of compact condensate removal pumps designed for long life and silent operation. These products are used in cases where condensate cannot be drain by natural downward slope or when the condensate source is located below the local backwaterlevel.

The design of CONLIFT includes a multitude of unique, patented features what makes the product together with the selected components and design very robust and reliable, particular towards the aggressive condensate coming from condensing boilers.

All required installed material is included and the unit operate full automatic.
The comparable large effective volume secure that the unit do not start more often than required.

6m drain hose as well as the adaptors for connecting condensate source drain pipe and discharge hose make the installation quick and easy. The smart balance system and the rotatable motor/pump unit enable to adjust to any specific installation situation.

The range consists of 3 tailored versions and all versions are operated by a maintenance-free motor incl. thermal overload protection.

CONLIFT1, the basic version, include a wired alarm contact what can be used to activate an external alarm device or to switch-off the condensate source in case of high water level inside the unit.

CONLIFT 2, the advanced version, comes with the same functionality but include an integrated alarm device what gives an acoustic signal in case of high water level and start the motor additionally to continue drain of condensate.

CONLIFT2 pH+ comes with the functionality of CONLIFT2 plus a flexible neutralisation unit for particular aggressive condensate from oil condensing or bigger gas boilers to protect the buildings and sewer piping system.

Thanks to the modular system, CONLIFT1 and CONLIFT2 can be upgraded with alarm PCB and/or neutralisation unit retrofit in case changed conditions should require this.


Typical application are for condensate from condensing boilers, chimneys, air-condition, dehumidifiers and refrigerators.

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.

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 cost.

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 cost.

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

The system offers a wider range of benefits and functions than mobile-phone-based monitoring. For those who do not require remote process automation, Grundfos Remote Management is the ideal solution for monitoring and remote control, rather than 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

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

Optimise service and maintenance

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

The communication interface (the CIU271 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. 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.

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 in WebCAPS include CAD Drawings and Literature.
