Paumps handle caustic, abrasive, acidic solutions
The D10 Series industrial pumps from Hydra-Cell Industrial Pumps are self priming, run dry without damage, and provide smooth, quiet operation at up to 8 gpm and 1000 psi
1700 series seals are fitted for applications handling extremely corrosive and abrasive materials.
The 1700 series eliminates the time, effort and cost of rebuilding conventional cartridge seals.
With its "disposable" inner cassette, users can easily replace seals in the field.
This eliminates redundant seal and gland inventory requirements, shipping and handling costs, service charges for expedited repair, and pump downtime for increased productivity.
Unlike the labour intensive and difficult installation procedures common to conventional seals, the 1700 series is as simple as popping in a new cassette, with a single pin lining up the seal with the reusable gland.
A friction drive lock ring with one cap screw assures alignment and eliminates slippage for easy installation.
Unlike conventional seals with centring clips that need to be removed before startup, these seals' self-centring locators are internal to the cartridge seal and are not removed.
This also allows the shaft to be conveniently rotated during assembly without effort.
