Updates & Tec tips
28-8-1998 Internet News Update N° 1.
The RL4056 (50Hz.) and the RL4057 (60Hz.) will be replaced by a new design stage
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..
