Larox Peristaltic Pumps for Dosing
The innovative Larox Peristaltic Pumps for Dosing (LPP-D) set a new industry standard for peristaltic pump technology. Designed and manufactured for the industrial mark etplace, they are ideal for pumping diverse slurries and dosing a wide range of media.
Operating Principle
The operating principle of the LPP-D pump is based on the peristaltic effect. As the cylindrical rotor rotates along the hose, the process medium gets pushed forward through the hose. At the same time, the hose behind the compression point reverts to its original circular shape creating a suction effect at the pump inlet port. As a result, the hose bore gets filled with the medium. No backward flow can occur as the hose is squeezed tight by the roller.
One Compression is All You Need
A single, bearing-mounted roller presses the hose only once per the 360 degree operating cycle, producing the maximum flow per revolution. Compared to conventional peristaltic pumps, the LPP-D doubles the flow per hose compression.
Unique Rolling Design
LPP-D pumps incorporate advanced rolling design which eliminates friction and lowers energy consumption. The roller is mounted on a crankshaft creating eccentric rotation during the 360 degree operating cycle.
Trailblazing Technology
Equipped with the standard technical features of a typical peristaltic pump such as dry run capability and self priming, the LPP-D pumps provide exact flow per revolution. Seal less pumps will not get damaged even if they run dry for longer periods of time. The LPP-D pumps are compact in design and require only a small footprint.
Ideal for Dosing
The trailblazing LPP-D pumps have a high turndown ratio making them ideal dosing and flow control. They provide accurate dosing in all process conditions as the pump discharge flow does not depend on the pipeline pressure.
Incorporating an advanced design, the Larox LPP-D pumps can offer unbeatable additional features including
- 360 degree operating cycle
- Only one compression per revolution
- Rolling hose contact
- In-line pipe connection
- Reliable hose connection
- Low lubrication need
and process benefits such as
- Higher flow per compression than any other peristaltic pump
- Extended hose life
- High pressure capability
- No overheating even at continuous flow rate pipeline pressure
