Solé Diesel impeller kit for short pump Mini-50/55/62

Description

Solé Diesel impeller kit for short pump Mini-50/55/62

This Solé Diesel impeller kit is intended for maintenance of the seawater pump on Mini-50, Mini-55 and suitable Mini-62 marine diesel engines. The kit is used with the short version of the water pump.

The flexible rubber impeller rotates inside the pump housing and ensures that seawater is drawn in and pumped through the cooling system. This seawater removes heat from the internal engine cooling system via the heat exchanger.

Technical specifications

Brand: Solé Diesel
Product type: Impeller service kit
Part number: 22.35111008R
Version: For short seawater pump
Application: Seawater cooling system

Contents of the kit

Impeller: Flexible rubber impeller for the seawater pump
Gasket: Matching cover gasket for resealing the pump

Suitable for Solé Diesel engines

This impeller kit is used on the following Solé Diesel marine diesel engines:

Solé Mini-50
Solé Mini-55
Solé Mini-62 – only version with short water pump

Please note for the Mini-62

For the Solé Mini-62, the version of the installed seawater pump is decisive. This kit is only suitable for engines with the short water pump. Therefore, check the installed pump or the part number of the existing impeller before ordering.

Function of the impeller

The rubber blades of the impeller are continuously bent inside the pump housing while rotating. This creates suction and pressure chambers that move seawater through the cooling system.

Sufficient cooling water flow is essential for dissipating engine heat. If the impeller pumps insufficient water, cooling capacity may decrease and the engine temperature can rise quickly.

Why should an impeller be checked regularly?

An impeller is a wear part. The rubber is continuously deformed during operation and is also exposed to water, heat and periods of inactivity. Over time, this can cause the blades to harden, crack or become permanently deformed.

If a blade breaks off, pump capacity decreases and pieces of rubber may be carried further into the cooling system. These pieces can, for example, accumulate in pipes or the heat exchanger and restrict cooling water flow.

Possible signs of a worn impeller

Reduced cooling water discharge: Less cooling water from the exhaust than normal
Higher engine temperature: Engine runs hotter than usual
Damaged blades: Cracks, missing sections or permanent deformation
Hardened rubber: The impeller feels stiff or dried out

Preventive maintenance

Check the impeller at least during periodic engine maintenance and replace it preventively when the condition of the rubber is no longer good. With seasonal use, the impeller is often checked or replaced annually.

During replacement, also check the pump housing and cover plate for wear. If parts of the old impeller are missing, they should be removed from the rest of the cooling circuit where possible before the engine is used again.

Installation

Install the impeller according to Solé Diesel specifications and fit the new cover gasket correctly. After installation, check that the pump is leak-free and that sufficient seawater is pumped through the cooling system immediately after starting.

Do not allow a rubber impeller to run dry. Without water, the impeller can be damaged in a short time.

Useful as a spare part on board

An impeller is an important spare part to keep on board. If the impeller fails, the cooling water supply may decrease significantly or stop completely. With a suitable spare kit, the seawater pump can be restored more quickly while underway.
