Frequently Asked Questions (FAQs)

1. What is the pressure on a flexible impeller pump?

Flexible impeller pumps typically operate at low discharge pressures of 20-30 psi when using standard thickness impeller blades. However, thicker high-pressure impeller blades can increase the operating pressures to 60 psi or more.

2. What are the disadvantages of flexible impeller pump?

Flexible impeller pumps have a few disadvantages, including the inability to run dry, the vulnerability of the impeller as a wearing part that can be easily damaged, and unsuitability for high-pressure applications. Additionally, the pump's capacity can be significantly affected by viscosity, with a potential 60% capacity drop at 4000 cps.

3. What are the disadvantages of impeller?

Impellers, especially those made of rubber in flexible impeller pumps, can be easily damaged due to constant wear and tear. This can lead to the impeller shedding rubber particles into the fluid being pumped, which may not be desirable in certain applications.
