Seal of approval for no-clog pump
CLOGGING is not a problem on a new slurry pump, says Suffolk-based maker Cornell Pump.
The 2.5HM model incorporates a seal design in which the dished backplate works with the impellers backvanes to create a centrifugal action. This draws sand and grit away from the seal as well as dispersing air and gas pockets. The result, Cornell claims, is extended seal life and no need for venting or water flushing.
Available with capacities up to 1660 litres/min (365gal/min) and pressures to 175psi, the 2.5HM pump is designed for use in slurry/dirty water irrigation systems. Price is £3247 (01284-706922).
