Pulsation-free flow enhances gentle processing of fragile products and eliminates costly damage while greatly reducing wear to pump, related piping, and instrumentation.
This allows the disk pump to pass large and irregular hard solids as well as a variable solids stream without plugging.
The disk low NPSH ranges from approximately 1/3 to 1/2 that of conventional centrifugal pumps in the same service due to the smooth laminar flow generated by this design.
The disk pump design is capable of being operated indefinitely with zero process fluid.
NOTE: The mechanical seal must be flushed during dry-running.
It is possible to deadhead the discharge and/or starve the suction for extended periods of time at normal operating speeds with no damage to the pump. (Not including sealing device unless it is properly protected and lubricated.)
Exceptional low radial and axial loads generated by the disk rotor result in extended seal, bearing, and shaft life. This is attributed to laminar flow within the disk.
Capability of handling a wide range of conditions without requiring internal modifications, even with large variations in process viscosity, temperature, solids type or concentration without process interruption.
Few, if any, spare parts are required for the disk rotor pump over its life. The oversized shaft, along with minimal axial or radial loads, greatly extend and maximize bearing and seal life.
Disk rotor pumps are subject to minimal wear even in the most abrasive services due to minimal fluid to pump service contact and laminar flow characteristics.
TESLA DISK PUMPS™ are simply the most reliable pumps on the market for hard-to-pump applications. The disk rotor has no close tolerances thus enhancing minimal fluid contacting action. This factor contributes to maximum run time by reducing excessive wear on the internal wet-end preventing unexpected failures.
When pumping delicate, shear sensitive, or otherwise sensitive products, the disk rotor increases productivity by reducing product losses due to the minimal contact pumping mechanism and laminar flow. Savings can be phenomenal with some pumps actually paying for themselves in a matter of weeks.
