## Questions & Answers

**Q: Advertised as 80 F max Temperature is this correct or is this 80 C ?**
A: 80f seems low, 80c seems high

**Q: do i need to get an air regulator?**
A: Not if your air supply is 100 psi or less. You van use a simple ball valve for on and off and to vary the speed. These are awesome pumps but use a LOT of air, so you need a higher cfm compressor.

**Q: Will this pump work for pumping a slurry or sludge with liquids?**
A: Hello, Dear friend,
Thank you for your love of our products. If the sludge has water and is not very sticky, you can use this diaphragm pump. Thank you for your understanding! Welcome to buy!
Have a good day!
Best Regards!

### ⭐⭐ Review
*by C***8 on 24 December 2023*

bought 2 and neither worked. since I was past the return deadline, I had to take them apart to see what was wrong. 1 leaked and the balls would not seal. and one was put together backwards so when it pumped it went within itself.
