Schulz Brand, Cast Iron, Model: 18 Air Compressor Pump + FREE Intake Filter Assembly-

 
This listing is for a Schulz model 18 cast iron, oil lubricated, air compressor pump. This is a long lasting industrial quality pump. This pump will work with a 2, 3 or 5 peak horse power motor, these sizes of motors are usually 15-19 AMPS if your 5HP motor is 22 AMPS or larger you need to use a larger pump than this. Keep in mind, if using a 2 horse power motor you will have to spin the pump slower so it does not overload the motor which means the CFM output will be lower. With a 2 HP motor your CFM will be around 6-8 CFM on average, with a 5HP motor spinning at max RPM, your displacement CFM will be about 16-18. We recommend that you spin this pump between 700 and 1200 RPM for best results. Max displacement CFM is 18.

This makes a great replacement pump for most any air compressor with a 2 - 5 HP motor. With its slotted base, this pump will adapt to many tanks without any modification. If it does not fit your current pump's mounting holes, new holes can easily be drilled. The head and cylinder of this compressor can be flipped around to put the air outlet / discharge on either side of the pump for easy installation. If the fly wheel is a different size than the pump you currently have, it is easy to calculate what size pulley you will need to put on your motor. (you take motor RPM x diameter of motor pulley and divide it by diameter of the pump pulley) that will give you the RPM you pump will be spinning.
