FAQ
▔▔
1. What is the difference between a gerotor pump and an external gear pump?
A gerotor pump uses an internal gear design, which reduces noise and pulsation. External gear pumps are simpler but generally noisier. For applications requiring smooth flow and low noise, gerotor pumps are preferred.
2. Can the PGZ4-1X handle high pressure continuously?
It can operate at rated pressure continuously if proper cooling and filtration are maintained. Avoid running at maximum pressure for extended periods.
