The cooling water pump fits exactly for eg book DV20M. Pump cover with sensible screws. No slotted screws that can be damaged after opening. Since a later impeller change is easy to perform. \ R \ nPrice and performance is right in any case.

Quality product, and compliant. No problem mounting on my Volvo Penta MD7 A engine, and works perfectly.

Works like the original My total costs including installation have been reduced by 65% compared to the original Volvo Penta part. Works perfectly on my VP MD7A. Here and there the mechanic I trust had to shorten things a little - but that is minimal adjustments. Including the pump, all the fun didn't cost me 350 €. For comparison, Volvo currently wants around € 900 plus around € 300-400 installation costs for the part. Top service and advice from SVB! with which you have won a new regular customer.

easy to swap The 45-year-old pump could easily be exchanged for the new seawater pump. Only the pipe on the pressure side needs to be shortened and replaced with a hose.

Class Very good replacement for the expensive original part, fits perfectly. The connections for the water pipes are different but this is easy to solve with adapters. Can't say anything about the lifespan yet.

Note:

This product is delivered in original equipment manufacturer (OEM) quality. It is not the original product from the manufacturer.

The life of a seawater pump is limited, even if maintenance activities such as replacement of sealing and impeller are performed regularly. The reason for this is corrosion, which is caused by the constant condensation of the pump even if the engine is at a standstill, as well as material removal due to erosions as a result of the high flow speed of the seawater inside the pump housing. OEM quality.

Often small but steadily increasing leakages, usually at the bottom of the housing, are signs of a pump's demise. At that point, you should think about a replacement.
In order to assist skilled skippers in carrying out their own repairs without causing a total loss, we are now offering seawater pumps for the most common types of engines on the market. Dimensions, connection widths, flow rates and shaft diameters are provided in the table. Here you can also find information on which pump is suitable for which engine manufacturer / type of engine.
