  • Double-cone device and pump
    Publication number: 20040104023
    Abstract: The performance of a double-cone device (1) is increased, not only by moving the gap or inlet openings (22) a short distance into the exit cone (47), but also by making the conicity &thgr;3 (55) of the so-formed small diffuser less than the conicity &thgr;2 (109) of the remaining part (53) of the exit cone. Double cone units (7, 60), particularly the ones with this improved diffuser, may be used in pump installations (1, 60), like well-pumps (1), where liquids must be pumped from great depths.
