Stainless steel gear pumps from the manufacturer

WITTE is a manufacturer of stainless steel gear pumps. Our special stainless steel chemical pumpsare mainly used for transfer tasks and dosing applications.

Stainless steel gear pumps of the CHEM series are extremely flexible in their design and can be offered in various variants and configurations thanks to a modular system.
Stainless steel gear pumps for differential pressures up to 120 bar, suction pressures vacuum up to 15 bar
Stainless steel gear pumps for temperatures up to max. 500 °C in combination with a magnetic coupling.
Stainless steel gear pumps for viscosities up to 1,000,000 mPas or higher.
Stainless steel gear pumps with throughput from 20 l/h to 170,000 l/h

Stainless steel gear pumps from the CHEM series are designed and assembled exclusively in Germany. On request, we install the stainless steel pumps directly in our customers' systems and are on site during the start-up phase.

We also offer a comprehensive maintenance and repair service for our stainless steel gear pumps.

We have spare parts for many pump sizes in stock at our branches in Germany, the USA and China.

In the event of damage to our stainless steel pump, our service technicians can be on site within 24 hours in Europe and within 48 hours in most non-European countries.
