How to check the fit

Check the aluminum or stainless-steel pump configuration and all wetted materials against the coating, solvent and operating temperature.
Match the bare-pump installation
Check the different inlet and outlet sizes, air supply, required flow at pressure, mounting, hoses and regulators.

Selection & Installation
- Confirm the complete part number and supplied revision before ordering.
- Check fluid chemistry, concentration, temperature and solids against every wetted material.
- Size the air supply and pump using the required flow at discharge pressure; maximum free flow is not the flow available at maximum pressure.
- Check the inlet and outlet separately: this pump uses different fluid connection sizes.
- Confirm material compatibility and the equipment manual before handling solvents.
