FLSmidth Pfister History

Tradition in progress

FLSmidth Pfister GmbH is an engineering company with tradition. Founded more than 120 years ago in Augsburg, headquarters of the worldwide active company is still in this city in the south of Germany.
Since its beginnings, FLSmidth Pfister has established itsself with a large number of technical innovations in many application fields and branches. FLSmidth Pfister also experienced interesting times, amongst which was the biggest revolution in weighing during the 20th century: the change from mechanical to electronic weighing.



Ludwig Pfister, a blacksmith, establishes a scale company to manufacture mechanical weighbridges in the old section of Augsburg. 


On the 26th of November, the 25th wagon scale is completed and delivered to its operating site by a "team of four dressed horses". The site is the new municipal weighbridge for the city of Augsburg.


Ludwig Pfister's seven children join the company as limited partners. The workforce increases to 70 factory and 10 supervisory employees. A 200 m2 assembly hall is built for large-size weighbridges.


Construction work is commenced on the present factory site at Stätzlinger Straße 70, Augsburg.


1955 - 1958
A special dial head is developed which is destined to become the trademark of countless concrete mixing systems.
Shortly afterwards, Pfister launches a further innovation into the market: A mechanical programmable weighing device which provides an electrical contact field for
presetting of weight values.


Pfister combines a direct extracting system with conveyor weighfeeders, which is the initial approach to continuous industrial weighing technology. This is the start of a successful new product range and represents the origin of the present day Pfister company.


The first weighfeeder with lateral belt replacement is developed and delivered to a sintering plant in Germany. This design becomes the standard for all future weighfeeder models.

The family business is acquired by Klöckner-Humboldt-Deutz AG.
The electromechanical weighing technology is developed and the first Pfister digital indicator, the DK 4000, was awarded its certification approval. This is the origin of the fully electronic Pfister scale.

The development and sales of the hydrostatic wind tunnel scale for the automobile industry proved to be a successful entry into a new market.
Leading automobile manufacturers such as Daimler Benz, BMW, Ferrari, VW, Ford, Fiat and many others use the Pfister high tech scale to optimize vehicle aerodynamics.

The first Pfister scale, model DSR, with a process controller is released. It represents the first in a product line that is represented today by the model DWT weighing terminal.

Pfister extends its product availability with the introduction of a certifiable TWE tank weighing system which can provide mass, density and volume data for multiple large tank systems within a fuel depot.

1982 - 1983
The first compact DWT 10 weighing terminal is introduced. When used with the rotor weighfeeder Pfister® SFW truck weighbridge, it provides certifiable recorded weight data.
Pfister is acquired by the French Metrologie Pesage Int. S.A. group.

A innovative and highly successful new product line is launched with the development of the rotor weighfeeder Pfister® DRW dosing rotor weighfeeder for pulverized coal and coke.

Pfister is acquired by the Dutch N.V. Koniklijke Nederlandsche Machinefabriek v/h group.

Maximilian Scheugenpflug becomes the majority shareholder in the company. Its co-partner is the Deutsche Beteiligungs mbH Frankfurt (Deutsche Bank group).
Pfister introduces the modular designed SFW truck weighbridge featuring preassembled concrete parts.

Dynamic weighing technology is born when Pfister installs the first Sirius weighrail scale for in-motion weighing of rail cars.

Pfister developes and introduces the rotor weighfeeder Pfister® FRW which was primarily designed in order to optimize the calcining process by insuring uniform heat exchanger feeding. Due to the much improved dosing properties and increased reliability when compared to other systems, both the efficiency of the calcining process and the clinker quality are improved. In addition, the completely enclosed design maximize dust pollution containment.

Pfister installs the first rotor weighfeeder Pfister® TRW-S for secondary fuels. With the introduction of rotor weighfeeder Pfister® TRW-S/D Pfister positiones itself as the main supplier of the most advanced dosing systems for secondary fuels. Like all rotor weighfeeders it is a completely enclosed system which minimizes dust contamination of the surrounding work area. It represents an accurate and reliable way of disposing of invironmently sensitive waste in the most cost effective manner.

Pfister becomes a subsidiary of the Danish F.L. Smidth-Fuller Engineering (FFE) group. With over 4000 employees, the FFE group is active globally in the cement and mineral industries, providing equipment, construction and engineering services.

The microprocessor based control, Pfister® CSC, is introduced for use with the Pfister® rotor weighfeeders. Its patented prospective control algorithm, ProsCon®, represents a new approach to continuous feeder control.

The new Pfister® Winweigh Plus software, which is based on the Windows NT software package, elevates weighing data management for static truck weighbridges to new levels of effectiveness. The Pfister® Solar railroad track scale sets a new standard in the dynamic weighing of rail cars.

The operational business of Pfister Waagen GmbH is sold to the italian specialist for weighing Technologies, Bilanciai, as of June 1st, 2002. Pfister Group thus successfully realizes its strategy to concentrate on its core business in order to bundle its efforts and strengths.

The "Integrated Feeder Controller Pfister® iFC", an electronic control unit for FLSmidth Pfister dosing equipment, is launched. Due to the special construction of this unit a competitive advantage could be gained in terms of costs and handling of the dosing electronics.
Also developed and introduced to the market is a mill controller. This integrated dosing system for mill feeding is rounding up the FLSmidth Pfister product portfolio concerning linear conveyor systems.

FLSmidth Pfister systems being certified with the new ATEX directive 94/9/EC which provides the technical requirements to be applied to equipment intended to be used in potentially explosive atmospheres. Besides, ISO 9001 is renewed for FLSmidth Pfister.

FLSmidth Pfister celebrates 3 anniversaries: The company turns 110 years, 40 years of continuous weighing technology, and 20 years rotor weighfeeder. Another manufacturing site is opened in Qingdao (China). Also, from now on FLSmidth Pfister is offering one more apprentiveship program for "mechatronics".

Pfister introduces two innovative dosing systems: the dosing chain weighfeeder Pfister® DCW for dosing hot and viscous bulk materials and the dosing field weighfeeder Pfister® DFW.
The first rotor weighfeeder Pfister® DRW for the Chinese cement industry is assembled in Qingdao.

Pfister enters an additional business segment: the rotor weighfeeder technology is successfully introduced to the power plant industry.
