Our history

Since our foundation in 1983, our company has developed from a trading company into a leading manufacturer and system supplier of progressive cavity pumps. Through continuous expansion, technological advances and a strong commitment to quality and sustainability, we have steadily increased our production capacity. Below you will find an overview of the most important milestones in our company history.

1983

Foundation and first steps

Gunnar Otto founds the company and sets it up as a trading business in his parents’ house. From the very beginning, he acquires the business from scratch and lays the foundation for future development.

1995

Transformation to production

A decisive turning point: the focus shifts from trading to manufacturing. Gunnar Otto puts together a team of specialists from various pump parts production areas, which has been working with a high level of expertise and customer orientation ever since.

2010

Expansion through integration

The company continues to grow with the integration of Wotex Pumpen- und Fördersysteme. This step strengthens the product range and market position.

2013

Reinforcement through M-P-S mono pump service

Another milestone: The integration of M-P-S Monopumpenservice, which Gunnar Otto founded back in 2005, expands the company’s expertise and production capabilities.

2018

New production hall

The move to a modern production hall for rotors and solid stators marks a significant development step. The new premises enable more efficient and higher quality production.

2019

In-house rotor production

Another step forward: the company starts manufacturing its own rotors. This increases production capacity and strengthens independence.

2020

Expansion of the machine park

The expansion of the machinery enables the production of a wider range of pump parts. This increases flexibility and the range available to customers.

2021

Sustainability with photovoltaics

The company focuses on renewable energies and commissions a 75 kW photovoltaic system in Dorsten. This underlines the company’s commitment to sustainability and environmental protection.

2022

Expansion of the production hall in Dorsten

Due to increasing demand, the production hall in Dorsten is expanded. This creates more capacity and strengthens competitiveness.

2023

More efficient work processes

The office staff move to new premises at the production site in Dorsten. This improves communication and collaboration. In addition, a further 45 kW photovoltaic system is installed in Gehrden.

2024

Modern energy supply

The installation of new air compressors at both sites ensures a sustainable and reliable energy supply in line with the latest technical standards. This underlines the continuous pursuit of quality and innovation.

Our locations

Our main site in Gehrden is the center of our elastomer production, in particular the production of rubber stators. Our toolmaking, paint shop and development department are also located here.

Our branch in Dorsten specializes in metal processing, in particular rotor production, as well as plastics processing for solid stators. This location is also home to our central warehouse.

Social commitment

Gehrden Volunteer Fire Brigade

We support the Gehrden volunteer fire department both financially and with the opportunity to carry out exercises directly on our company premises. These regular fire department exercises make a significant contribution to establishing, maintaining and developing an operational, well-trained fire department.

The Gehrden food bank

Not everyone has their daily bread – even though there is an abundance of food. The food banks try to compensate for this – with volunteers, for the needy in their town. The aim of the food banks is to distribute all good quality food that can no longer be used in the economic process to those in need. The food banks help these people to get through a difficult time and give them motivation for the future.

We support the local food bank in Gehrden with donations, as the running costs can only be covered with these.

Workers' Samaritan Federation

Since it was founded in 1888, the Arbeiter-Samariter-Bund (ASB) has offered services that are geared towards people’s needs. They help everyone who needs our support quickly and directly in a variety of ways.

ASB's services at a glance:

  • Elderly care
  • Rescue service
  • First aid
  • Child and youth welfare
  • Workers' Samaritan Youth
  • Help for people with disabilities or mental illness
  • Training and further education
  • Foreign aid
  • Further services
We support the registered association with donations.
