#CMT# #/CMT# The pump has a driving fly-wheel carrying a permanent magnet annulus gear. A baffle plate (6) is intercalated in air gap between the rotor and the fly-wheel. A front wall assures the separation between aspiration and discharging zones of liquid medium. A sliding sealing device i.e. tubular part (16), is inserted between the wall and the rotor with the interposition of supports (17, 18) for compensating the misalignment between the wall and the rotor. The supports are made of deformable material and realize the assembly of fixed and rotating thrusts (13, 14) of the device with retaining effect. #CMT#USE : #/CMT# Magnetic drive pump for conveying liquid e.g. corrosive liquid. #CMT#ADVANTAGE : #/CMT# The utilization of the sliding sealing device assures the good sealing of the pump even in the case of separation of the thrusts and even when the rotor is solicited towards rear. The pump avoids the problem of misalignment between the front wall and the rotor. The supports realize the assembly of the thrusts with the retaining effect, thus avoiding the accidental fall of the thrusts, the tubular part and the supports during handling and dismounting. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an overall sectional view of a magnetic drive pump in which sliding sealing device intervene like an auxiliary bearing. 2 : Radial-flow impeller 6 : Baffle plate 13, 14 : Fixed and rotating thrusts 16 : Tubular part 17, 18 : Supports. |
