Non-Clog Pumps
 
Griffin's Variable-Use, Vacuum-Assisted, Non-Clog Pumps are available in 4" to 18" models. These pumps are fully automatic, dry-priming and dry-running, non-clog portable pumps. They operate efficiently under continuous or intermittent flow conditions.

These pumps are capable of handling flow up to 17,000 gpm and head conditions up to 240 ft. The pumps are available with the Wind Tunnel® high volume air handling system, vacuum assisted, compressor primed or diaphragm vacuum pumps. The pumps air handling capacity ranges from 50 to over 200 cfm. The pumps automatically prime and reprime at suction lifts of 25 ft. and greater. The non-clog impellers can handle spherical solids up to 3" and larger.

These pumps are available in diesel or electric models most are equiped with an integral fuel tank and can be trailer mounted. Other options are available with these units. Contact Griffin for more information and options available.
