ABSTRACT:
A progressing cavity pump having a rotor (13) which rotates and orbits within a stator (14) is provided with the stator (14) being connected at one end to a hopper (12) containing the material being dispensed by a flexible tube (26) and to a fixed joint (29) at its other end. This fixed joint (29) and a flexible joint (21) connecting the rotor (13) to a rotary drive means (20) are positioned outside the material, for easy observation; together with the flexible tube (26) such joints permit the rotor (13) to rotate and to orbit conically about the flexible joint (22) and the stator to orbit conically about the fixed joint (29), 180.degree. out of phase with the rotor.
The apparatus is particular suited to handle a water gel explosive which might create a safety hazard if the explosive enters a joint without detection.
