# 21212798 Pump | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine belt-driven flexible-impeller seawater pump for later Volvo Penta 3.0GLP petrol marine engines. It replaces pump 3812522 and uses a 1-1/4 inch inlet, 1 inch outlet and approximately 6-1/2 inch serpentine pulley.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta 3.0GLP-D
-   Volvo Penta 3.0GLP-E
-   Volvo Penta 3.0GLP-J
-   Volvo Penta 3.0GLP-N

## ⚙️ Key Features

-   Current replacement for pump 3812522
-   Belt-driven flexible-impeller design
-   1-1/4 inch inlet and 1 inch outlet
-   Approximately 6-1/2 inch serpentine pulley
-   Dedicated 3.0GLP cooling-system configuration

## 🔌 Function

The pump draws raw water through the vessel intake and supplies the engine cooling and wet-exhaust circuits.

## ⚠️ Common Signs of Failure

-   Reduced or intermittent exhaust-water discharge
-   Missing or permanently set impeller vanes
-   Seawater leakage from the shaft seal
-   Bearing or pulley noise
-   Corroded pump body
-   Pulley wobble or belt misalignment

## 🛠️ Service Notes

-   Establish why the old pump failed before the new one goes on — debris, a blocked strainer, a starved supply or a dry run will take out the replacement just as quickly
-   Fit new gaskets, O-rings and seals on the pump's joint faces and drive, with the faces clean, and use only the sealant the workshop manual for your engine specifies
-   Check the drive and the shaft it runs on — coupling, gear, key, belt or drive dog — while access is good, and renew anything doubtful
-   Prime or fill the pump as the manual for your engine directs, bleed the system afterwards, and confirm it is actually delivering before the boat leaves
-   Tighten mounting and cover fasteners evenly to the manual's figures; pump housings distort easily, and a distorted housing either leaks or binds
