ABSTRACT:
The novel slave pump having a piston rod having a fluid passage through which catalyst is discharged for ultimate use. The slave pump also has an exterior casing which holds it together without contacting the catalyst or other fluids being pumped.
A novel combination of a slave pump as just described driven by a master pump having a cylinder and a piston rod, a slave pump having a cylinder and a piston rod, a first means interconnecting the piston rod of the master pump with the piston rod of the slave pump, and a second means connecting the cylinder of the master pump with the cylinder of the slave pump.
The position of the slave pump can be adjusted with respect to the master pump to change the amount of catalyst or other fluid delivered by said slave pump per stroke of the slave pump piston. The interconnecting linkages are provided with spherical connections to mitigate wear and binding due to misalignment.
