Re: Volvo D3 110 Sea Water Pump - Cover seal
toggle quoted messageShow quoted text
Good point Scott,
Disclaimer: I have never disassembled the D3 Raw Water Pump, and I am relying on drawing from Volvo.
I decided to take a look at the sea water pump for the Volvo D3.
I was surprised to find that there is not a typical spring loaded mechanical seal, but rather what Volvo calls a "Sealing Ring."
The Volvo TMD22 raw water pump has a "Sealing Ring" and a "Sealing Washer"
This is what a typical mechanical seal looks like:
The sea water pump in the Yanmar engines used by Amel incorporates a mechanical seal inside the pump
The sea water pump in the Onans used by Amel incorporates a mechanical seal inside the pump
All of the Calpeda Pumps, Dessalator Pumps, and All of the brands of the Amel installed freshwater pumps that I have seen incorporate a mechanical seal.
I guess I am predjudiced in my belief that a Mechanical Seal will last longer than a washer.
