Difference between the 7550 and the 7538 pump: 

  • The 7550: 75mm bore and a 50mm stroke
  • The 7538: 75 mm bore and a 38 mm stroke
  • The 7550 goes further up and down with each rotation, giving you a better performance at the same RPM
  • The 7550 has both holes threaded, with one 1/2" female port, and the second port 1/4" bolted hole. The 7538 is different in that it has only one 1/2" female port

The LaPlante 7538 is used by a number of air compressor manufacturers, so if the specs match your compressor, and it will mount to your air tank, this pump will work. The listing is for the bare LaPlante Compressor pump and wheel, only. You will need to check the oil level and add compressor oil as necessary upon receipt.
