The Optima Series precision gear pumps are an ideal choice for applications that require a constant high pressure delivery volume but are also limited in space requirements. A well designed concept makes this possible. Removing one bearing reduces the overall length. The small magnetic coupling also creates space savings while at the same time maintaining the high-pressure characteristics.

However, the Optima Series does not cut back on quality. The materials and the gear pump design are identical to those used in larger pumps. The spectrum of delivery volumes ranges from 1,000 to 2,500 milliliters per minute, available in both BLDC and DC motor versions.

The Optima Series is made of chemically resistant materials and thus suitable for a variety of fluids. It is also a preferred choice for pumps in the food and beverages industry, from the perfect milk foam for coffees to super-smooth soft ice creams.

Benefit Icon


DPP pumps are all characterized by their robustness and performance. Wear and tear is at its lowest, and their smart designs ensure a sustainable reduction of operating costs.

Benefit Icon

100% Outgoing Testing

Before departing from our factory, each pump undergoes rigorous and thorough testing, adhering strictly to its specifications. Our clients receive comprehensive reports, saving them both time and money.

Benefit Icon

Chemically Resistant

Our pumps are made from materials that are resistant to a wide range of aggressive chemicals. This means our pumps can also operate reliably and precisely in even the harshest environments.

Benefit Icon

Low Pessure Pulsation

Thanks to their smart drives and the innovative helical gear design our pumps ensure an extremely smooth fluid delivery with almost no pressure pulsation.

Benefit Icon

No Shaft Seals

DPP gear pumps are hermetically sealed instead of using conventional shaft seals. This means low maintenance for you and your customers, a long service life and the highest degree of productivity.
