Compact, eco-friendly and quiet.

Space-saving with high performance, plug&play, no wiring required and minimum interfaces.

Our customers benefit greatly from the reduction to one single interface in order processing and significantly minimised effort due to:

  • Established processes and partnerships that ensure solution-oriented engineering and on-time material procurement.
  • Our technicians are highly competent, friendly and resilient when it comes to installing and maintaining our systems, including offshore.
  • Due to our close cooperation with international insurers, we always find a safe solution during inspections.
  • Our documentation is precise, easy to understad and functional.

We are a system supplier and a problem solver with VdS approval.

Base frame
Base frame
  • Made of self-developed edge profiles
  • Completely hot-dip galvanised in a full bath, according to DIN EN ISO 1461 with a protection duration class C3
  • Due to steel sheets with increased material strength and corresponding construction, a considerably higher torsional stiffness is achieved than with comparable sectional steel base frames
  • On request divided for better handling on the construction site

On request with SCHALLEX – structure-borne sound insulation

External mounting brackets
External mounting brackets
  • External, easy and time-saving installation
  • Installation with special fastening accessories without displacement of the pump set
  • Integrated center holes as loading points for crane/transport
Jackscrews
Jackscrews
  • For easy alignment of the pump set
Controller
Controller
  • Front door labelling in the language of the order
  • unit name plate showing technical data and approval numbers of the main components
  • Elastic, vibration dampened mounting of the controller
  • Pressure switch assembly completely installed and wired with wire break and short-circuit monitoring, piping with connection for flushing, discharge hose pipes for leaking water accumulated during tests of the unit, pressure gauge with dual scale showing measurements in bar and PSI and with adjustable pointer to mark the starting pressure

Foot valves
Foot valves
  • With or without flat suction basket, completely hot-dip galvanised
Laser adjustment
Laser adjustment
  • Each unit will be tested using laser-optics and finely adjusted before delivery
  • Metal spacers for fine adjustment in different thicknesses compensate alignment errors and allow re-adjustment after installation and during start-up
  • An adjustment protocol is always included in the scope of delivery
