Marine Fixed Pitch Propeller (FPP)

We can supply conventional FPP propellers and propeller shafts following the drawings provided by our customers.

A marine fixed pitch propeller is also known as a fixed-pitch screw. Its blades and the hub cannot be changed during operation.

• Material: The maker usually produce a marine fixed pitch propeller with strong and durable materials. For example, bronze, nickel-aluminum bronze or stainless steel.
• Number of blades: The number of blades on a fixed-pitch propeller can vary depending on the application, but 3 and 4 blades are common.
• Pitch: The pitch of a propeller refers to the theoretical distance a propeller would travel in one revolution in a solid medium. The angle of the blades determines the pitch. The pitch is a crucial factor in determining the prop’s efficiency at a given engine speed.

Features

• Simpler design: Fixed-pitch propellers are typically cast in one piece. Thus, it is less complex and cheaper to manufacture than controllable-pitch propellers.
• Lower maintenance: With no mechanisms for adjusting the pitch, fixed-pitch props require less maintenance.
• Lower efficiency at varying speeds: Since the pitch is fixed, they may not be as efficient across a wide range of engine speeds and operating conditions as controllable-pitch propellers.
• Better for steady operation: Fixed-pitch propellers are ideal for applications where the vessel operates at a relatively constant speed, such as cargo ships and tankers.

Application

Applicable to all conventional ships and boats.
