the inlet 31 and the outlet 32 are designed to be closable, so that in the operating state, a barrier liquid is introduced into the seal housing 19, through which the annular space 29 is filled.
a solvent-containing fluid is used as the barrier liquid, in order to dissolve the paint particles possibly emerging through gap leakage within the annular space 29, so that hardening in the gap is prevented.
the mobility of the pressure ring 22 is ensured.
a flushing of the annular space 29 via the channels 30.1 and 30.2 and the inlet 31 of the outlet 32 can be performed in a simple manner during maintenance and replacement of the barrier liquid.
the embodiment of the gear pump according to the invention shown in Fig. 2 and 3 is particularly suitable to carry out the metering of paint colors with high operating pressures.
a return of the gear pump is set in a color change to initiate a color change.
Higher operating pressures are usually achieved here, but due to the prestressed stuffing box packing, they can be safely withstood without the risk of leakage.
the embodiments of the gear pump according to the invention shown in FIGS. 1 to 3 are exemplary in their construction and design of the individual components.
the support bearing formed outside the pump housing on the drive shaft can be formed by other conventional storage means for radial and axial support. It is essential here that an axial force is applied to the compressive forces acting on the drive shaft. This can in particular reduce the signs of wear on the driven tooth.
the radial support of the drive shaft leads to increase the bearing life within the pump housing, in particular an externally acting transverse load on the drive shaft is reduced.
