SILENCER LD SERIES GEAR PUMPS FSDIENER Precision Pumps The Silencer LD is an economic solution for lighter duty applications not requiring the extreme capabilities of the Silencer series but still providing a durable, leak-free, reliable, chemically inert and quiet solution. The space-saving design offers customers multiple port options for easy installation. Custom casting designs can be created for higher volume OEM needs. A magnetic coupling ensures the pump will never leak, and high-quality wetted materials are chosen to withstand a wide range of aggressive chemicals. The Silencer LD Series - Engineering Your Flow. > Life Science Analytical - Diagnostics > Bulk & Sample Fluid Transfer > Dialysis Degas and Dialysate > Fully Automated Coffee Machines > Continuous Ink Jet Printing > Industrial Cooling 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. Chemically Resistant: Our pumps are made from materials resistant to a wide range of aggressive chemicals, operating reliably and precisely in even the harshest environments. 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. Low Pressure Pulsation: Thanks to their smart drives and innovative helical gear design, our pumps ensure extremely smooth fluid delivery with almost no pressure pulsation. 100% Outgoing Test: Before any pump leaves our factory, it is stringently and extensively tested in accordance with its specifications. Our customers receive detailed test reports, to confirm performance. 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.
