Description

The Pedrollo ST4-16 mechanical seal is used for 4-inch submersible motors and submersible pumps.

Suitable for electric pumps with a 16 mm crankshaft.

The ST4-16 mechanical seal used in electric pumps working inside wells.

The mechanical seal's job is to keep the hydraulic part separate from the electrical part. It prevents water from reaching the bearings and motor.

The ST4-16 seal allows shaft rotation without using a rigid seal.

The seal consists of two parts: a rotating one and a fixed one. It is made of ceramic, silicon carbide, NBR, and AISI 316 stainless steel.

The seal inside the electric pump is one of the most stressed parts and is therefore subject to wear. It's important to replace it when water is found in the motor.
