The new in-line pumps of the Etaline L series complement the lower end of KSB’s range of close-coupled pumps.

The small close-coupled pumps in in-line design are available in 12 hydraulic sizes and their motor rating ranges from 0.12 to 3.0 kW. The pump series covers flow rates of up to 95 m3 and discharge heads of up to 21 m.

The cast casings and the mechanical seals are designed for operating pressures of up to 10 bar. The connections at the suction nozzle and discharge nozzle can be either flanged or threaded, depending on the size. A confined O-ring reliably seals the casing, also in fluctuating operating conditions.

The pumps are fitted with mechanical seals selected for a maximum operating temperature of 120°C. They can be supplied in a large range of different materials. Depending on the application and size, the impellers with their good suction behaviour can be made of grey cast iron, bronze or polysulphone.

A fixed speed drive and a variable speed drive are available with a motor-mounted PumpDrive variable speed system. Both three-phase motors and single-phase AC motors are also available for this type series. The pump sets are available for horizontal or vertical installation.
