Silencer LD precision gear pump extends the successful Silencer series to even lower cost applications. This new deviation maintains the inexpensive, maintenance-free motor system while taking advantage of manufacturing technologies to reduce cost and size.

A redesign of the bearings allows for significant cost savings while still providing the life that Silencer pumps are known for at pressures up to 4 bar.

The 316L stainless steel casting allows for numerous port options at different orientations. Mounting holes are provided for easy integration into customer machines. Custom body designs can easily be provided for high volume OEM applications.

Benefits

Benefit Icon

Low Cost

Not all applications require maximum pump capability. Silencer LD has been optimized to lower cost while still providing superior Diener quality and reliability.

Benefit Icon

Long-life

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 any pump leaves our factory, it is stringently and extensively tested in accordance with its specifications. Our customers receive detailed reports, saving them 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 most environments.

Benefit Icon

Low Pressure 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.
