Frequently Asked Questions
Q: Do you have any Rocker Repair Videos to help maintain my items?
Yes, we do! Check out our Rocker Repair Channel here
Q: Can I operate my Rocker vacuum pump in an orientation that is not level?
No. Rocker vacuum pumps must be operated on a level, flat surface. Running Rocker 300 or 400 series pumps when they are tilted or not level can cause the prote® protection device inside the inlet filter to close, which may restrict airflow and reduce pump performance.
Q: Can I move my Rocker vacuum pump while it is operating?
No. Rocker vacuum pumps should not be moved while operating. Before moving the pump, turn it off and open the inlet to atmosphere to release vacuum. Moving a running Rocker 300 or 400 series pump can cause the prote® protection device inside the inlet filter to close, which may restrict airflow and affect pump performance.
Q: My Rocker 300 series, or Rocker 400 series, vacuum pump is operating but there is no vacuum at the inlet hose barb. What is the problem?
The Prote protection device within the inlet filter may have closed inadvertently. This commonly occurs if the pump was not level, or was moved, while operating. To reset the Prote protection device to the open position, the inlet filter bowl and filter must be removed so that the Prote float can be lowered to the open position. Once the Prote float is in the open position, the filter and bowl can be reinstalled.
Q: I would like to change the inlet fitting on my Rocker 300 or 400 series vacuum pump. What are the inlet port threads?
For the Rocker 300, and 400 series vacuum pumps, the inlet port has 1/8in BSPT (British Standard Pipe, Tapered) threads
Q: Why can I no longer find the Rocker 800 and its accessories?
The Rocker 800 series vacuum pumps and accessories have been discontinued and have been replaced by the Rocker 900 series, which offers updated performance and features.
