FAQ ：

Q: What happens if I have solids in my liquid?

A: This pump is designed for that. It is insensitive to impurities. It can handle liquids with fibers and solid particles.

Q: Is the flow adjustable?

A: Yes. Flow rate is directly proportional to pump speed. You can use a variable frequency drive (VFD) to control the flow.

Q: Can this pump self-prime?

A: Yes, it has good self-suction performance.
