28-8-1998 Internet News Update N° 1.

The RL4056 (50Hz.) and the RL4057 (60Hz.) will be replaced by a new design stage impeller version.

The RL4156 and the RL4157, as you know the old design with two impellers, had a perfect performance, bur service and spare part costs were way too high. We have always received lots of requests for a pump that could be working on a head of 35 ~ 40 meters, but still give some water.

Our new impeller gives a max. head on 43 m.l.c. and max. flow on 920 Ltr./min. On 37 m.l.c. the pump still gives 200 Ltr./min. on 26 m.l.c., 570 Ltr./min.. etc... etc...
