RICKMEIER separator lubricating oil pump R25/10FL-DB1-G

For fluids with changes in viscosity or density during the process, this pump will not be greatly affected. If there is a damper, such as placing a filter or a limiter on the discharge side, the pump will push the fluid through them. If the damper changes during operation, that is, if the filter becomes dirty, clogged, or the back pressure of the limiter increases, the pump will still maintain a constant flow until it reaches the mechanical limit of the weakest component in the device (usually equipped with a torque limiter).

RICKMEIER separator lubricating oil pump R25/10FL-DB1-GThere is actually a limit to the speed of a pump, which mainly depends on the process fluid. If oil is being transported, the pump can rotate at a high speed, but when the fluid is a high viscosity polymer melt, this limit will increase significantly.

It is very important to push high viscosity fluid into the two tooth space on one side of the suction port. If this space is not fully filled, the pump cannot discharge accurate flow, so PV value (pressure x flow rate) is also another limiting factor and a process variable. Due to these limitations, gear pump manufacturers will offer a range of products in different specifications and displacements (the amount discharged per revolution). These pumps will be matched with specific application processes to achieve optimal system capacity and price.

RICKMEIER separator lubricating oil pump R25/10FL-DB1-GThe gear and shaft of the pump are integrated, using a through body quenching process, which can achieve a longer working life. The "D" type bearing combines a forced lubrication mechanism, allowing the polymer to pass through the bearing surface and return to the inlet side of the pump to ensure effective lubrication of the rotating shaft. This feature reduces the possibility of polymer retention and degradation. The precision machined pump body can ensure the precise fit between the "D" type bearing and the gear shaft, ensuring that the gear shaft is not eccentric and preventing gear wear. The Parkool sealing structure and PTFE lip seal together form a water-cooled seal. This seal does not actually touch the surface of the shaft, and its sealing principle is to cool the polymer to a semi molten state to form a self seal. Rheoseal sealing can also be used, which has reverse spiral grooves machined on the inner surface of the shaft seal to allow the polymer to be back pressed back to the inlet. For ease of installation, the manufacturer has designed a circular bolt mounting surface to match the flange installation of other equipment, making the manufacturing of cylindrical flanges easier.

The gear pump is equipped with heating elements that match the specifications of the pump, which can be selected by users to ensure fast heating and heat control. Unlike the heating method inside the pump body, the damage to these components is limited to one board and is not related to the entire pump
