From the CK Through the CL to the CG.

KRAL three screw pumps - series C.

Due to its short shaft, the three screw pump CK series is only available with a radial shaft seal. The three screw pump CK has internal bearings and is most often used as a vertical, submerged in-tank pump.

1 Radial shaft seal ring.
The three screw pump CK series is only available with a radial shaft seal ring.

The three screw pump CL series can be equipped with different shaft sealing options thanks to the longer screw set. External bearings are also possible. This pump line is used as a horizontal or vertical foot-mounted or flange-mounted pump as well as in in-tank vertical arrangements.

1 Longer screw set.
Thanks to the longer spindle an external ball bearing is optionally offered.

2 Seal housing.
Depending on the operational requirements various shaft seal options are possible for the CL series.

The CL three screw pump is the cartridge (insert) pump of the CG series. The various housing options allow enormous flexibility in terms of the liquid connections. An external overflow valve can optionally be attached to the CG three screw pumps.

1 Flexible connections.
If the outer casing is made from fabricated steel, then almost any positioning, direction, size, type and rating of flange can be achieved. It can be ideally suited to match the installation situation.

2 External overflow valve.
The overflow valve ensures that the liquid is rerouted should excess pressurization occur.

Housing variants.
Depending on the operational requirements cast iron or steel housings are offered for the CG series.
