The gunman remained barricaded inside the house with police urging him to surrender.
The SWAT team also evacuated suspects who police had arrested during the raid, and who were then also trapped in the home, police said.
The SWAT team moved in about five hours into the standoff that began after the man opened fire on officers as they served a drugs warrant in the north Philadelphia home.
"The officers and additional prisoners that were inside of the house with the shooter were safely evacuated.
The shooter remains armed inside," Philadelphia Police Department Commissioner Richard Ross tweeted.
All the wounded officers were in stable condition with non-life-threatening injuries, with television images showing several of them leaving hospital on Wednesday night, one with a bandaged head and arm.
