Volvo Penta DPH Duoprop Propeller
The Volvo Penta DPH is a powerful Aquamatic sterndrive with duoprop system. Two counter-rotating propellers run one behind the other on a twin propeller shaft. The front propeller generates the main thrust, while the rear propeller uses the current to generate additional thrust. This increases efficiency and reduces slippage.
Propeller series for DPH drives
Two main propeller series are used for DPH sterndrives:
G-series (Duoprop G)
-
Nickel-bronze-aluminum (NiBrAl)
-
3-blade front propeller
-
4-blade rear propeller
-
Sizes G2 to G10
H-series (Duoprop H)
-
Stainless steel propeller set
-
replaces the older G-series
-
higher strength and efficiency
-
3-blade front propeller / 4-blade rear propeller
Technical features
-
counter-rotating duoprop system
-
Front and rear propellers as a matched pair
-
Large blade area for high thrust
-
Shock-absorbing rubber bush in the hub
-
Galvanic insulation to protect the drive
Compatible Volvo Penta drives
Propellers in this category are suitable for
-
Volvo Penta DPH
-
Volvo Penta DPH-A
-
Volvo Penta DPH-B
-
Volvo Penta DPH-C
-
Volvo Penta DPH-D / DPH-E
These sterndrives are mainly used with Volvo Penta diesel engines of the series:
-
Volvo Penta D4
-
Volvo Penta D6
which generate a high torque and therefore require specially developed duoprop propellers.
Size ranges
The propeller sets are offered in coordinated pitch combinations, e.g:
-
G2 - G10
-
H2 - H10
Each size defines a fixed combination of front and rear propellers.
