Maurer Turbine blade nylon C

With these turbine blades, a Pelton impeller for a small water turbine can be easily created thanks to the cleverly selected shape of the base. Maximum jet diameter a = 11; blade width b = 30; shaft width c = 10; base width d = 18; flange collar width e = 11; jet circle distance f = 15; blade pitch g = 19.8. Material: glass fibre reinforced polyamide PA GFV (balls). Sprue not plastered. Weight: approx. 9.2g. Minimum jet circle diameter 130mm. Dynamic pressure up to 20 bar. Above 15 bar, the mounting disc must be made of steel; below this, aluminium is possible.

Machining table for turbine wheels: width 30mm; blast diameter < 11mm; groove depth 4.5mm; groove width > 6.5mm.
