Diaphragm Pump with VFD for 24h Slurry Service

Hi everyone,
I’m an engineer in Fairbanks, Alaska. We’re looking to source a 3" diaphragm pump with a frequency converter (VFD) for continuous 24h operation on a soil processing plant.
I found a pump on the ATO website that appears to be suitable. Still, before committing, I wanted to see if anyone here has experience with similar slurry applications or thoughts on electric vs. pneumatic diaphragm pumps for continuous duty.
Any feedback or lessons learned would be appreciated.

Any feedback or lessons learned would be appreciated.Hi Kevin, we need to know whether there is particulate matter in the pumped medium.
1. How big are the particles?
2. What material is used for the pump body?
We just need this information so we can recommend a suitable pump and frequency converter.

Hi! It’ll be used for pumping a slurry of sand and fines, about #140 mesh.
The pump will be installed between our clarifier and thickener tank, moving roughly 20 tons per hour of material.

Electric diaphragm pump: Maximum flow rate: 14 tons per hour; Diameter: 4 inches
Pneumatic diaphragm pump: Flow rate up to 20 tons per hour; Diameter: 2 inches
Which option would you choose?
