ST1-16 - 16 mm mechanical seal

The Pedrollo ST1-16 mechanical seal is used for small and medium-sized multistage Pedrollo electric pumps.

Suitable for electric pumps with a 16 mm crankshaft.

The ST1-16 mechanical seal used in multistage submersible electric pumps for water supply, well pumping, irrigation and pressurization.

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 ST1-16 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.
