The ideal solution for stripping applications


Klaus Union recently supplied this double volute twin screw pump series DSP-4C according API 676 3rd Edition to a large customer in Spain. The pump is supposed to act as a stripping pump handling hydrocarbons, FAME and palm oil mix. As special feature, the pump comes with our “Plug & Pump” cartridge design for easy and fast maintenance of the pump hydraulics. In addition, the rotors have an optimized design for a higher efficiency and better NPSH. The spool piece on the discharge flange is intended to fit the pressure safety valve according API 520/526 and to simplify customer’s piping layout. An API Plan 51 is a low maintenance solution to increase seal lifetime especially during phases where partial dry run can occur at the end of the stripping operation.

Flowrate: 220 m³/h / Viscosity: 0,5 – 65 mPas / Power: 74 kw

Together against Corona


That’s it, our third vaccination campaign has ended successfully. Many of our employees received their important booster vaccination.
Wir sind davon überzeugt, dass „nicht impfen“ keine Option ist, denn die Corona-Schutzimpfung ist der wirksamste Schutz vor schweren und tödlichen Krankheitsverläufen.
Stay healthy!

We roll up our sleeves


We deeply care for the health of our employees and their fellow human beings. For this reason, we have already organized appointments for the first and second vaccination of our employees last year.
We want to continue to contribute our important part to fight the pandemic, so KLAUS UNION will once again roll up the sleeves for the booster vaccination in January.

Merry Christmas & Happy New Year


We would like to thank you for the good cooperation and the trust you placed in our company in 2021. We wish you Merry Christmas, pleasant and peaceful holidays and Happy New Year! Stay healthy! Stay healthy!

20 kW energy savings


Another good reason for using our non-metallic containment shells: We have subsequently modified the first of three identical pumps for our customer to reduce both the power consumption and the external flush flow for bearing lubrication and magnet cooling significantly. The pump is a magnet drive centrifugal pump series SLM NVO, equipped with our largest hydraulics (400-400-500).
The metallic containment shell has been replaced by a non-metallic shell made of technical ceramics. Through the use of this new containment shell material, eddy currents are eliminated, reducing power consumption by 20 kW and the external flush flow by almost 90%.
