Questions before you decide
Can a used NASH 904T2 replace my existing pump?
Compare airflow at the same operating inlet pressure, then review the selected unit’s curve and seal-water conditions. Check the drive and installation interfaces.
What vacuum data should I send?
Provide the operating suction pressure and state whether the reading is absolute or gauge. Include airflow, seal-water temperature and current equipment details.
Can I use my existing motor and foundation?
Compare shaft speed, motor duty, coupling and load. Confirm base dimensions, connections and foundation against the equipment drawings.
