The midfielder, 34, looks set to leave Stamford Bridge at the end of the season after 12 years in west London.
Lampard's agent says his man will not be offered a new deal and Pulis believes his time with the Blues has been good for both club and player.
He has netted 193 times for the team and Pulis said: "I think Frank has been a fantastic player for Chelsea.
"He has been unbelievable and he is a great lad and they tell me he is a real top professional.
"Chelsea has been absolutely fantastic for Frank - just look at the medals and trophies he has won.
"As a young kid starting football, he needed a vehicle to be able to achieve what he has achieved.
"Whether the argument is that Chelsea should offer him a new contract or not, well that is not my decision. But I think it has been a great marriage."
As for the possibility of Lampard playing for Stoke next season, Pulis added: "He has played down south all his life and I can't see him wanting to move up north.
"I think if Frank was going to go anywhere, I'm sure it would be down south."
