Lifting of: waste water, excess water, muddy water, industrial water. Drainage of: septic tanks, drains. Qm 3 /h CHARACTERISTICS - Several impeller types: VORTEX, single-channel, two-channel. - The submerged motor cable inlet is protected 3 times against the infiltration of fluid. - Mechanical seal on the fluid side. - The UCB pumps are fitted with a block seal. ADVANTAGES - Several particle sizes: 5/7/8, several types of use depending on the type of impeller. - No risk of infiltration into the submerged motor chamber. - Completely leaktight motor part. - The cassette seal ensures reliable sealing: no bellows and no ageing through natural or chemical agents.
