TaperBoreTM Seal Chamber
Goulds optional TaperBoreTM seal chamber features an enlarged bore for improved lubrication and cooling of the mechanical seal. The patented design (No. 5,336,048) features a tapered throat and a vane particle ejector to keep solids away from seal faces and from building up in the seal chamber. Seal life is remarkably extended.
Dynamic Seal on Goulds 3175
Dynamic Seal – for Elimination of Mechanical Seal Problems; Reduced Maintenance Goulds Dynamic Seal pumps are designed to handle the tough applications where conventional mechanical seals or packing require outside flush and constant, costly attention. The major advantage is that through Goulds patented design (No. 5,344,163) external seal water is not required, thus eliminating leakage, pumpage contamination, product dilution and problems associated with piping from a remote source. Standard Model 3175 pumps can be fitted with a repeller between the stuffing box and impeller. At startup, the repeller functions like an impeller and pumps liquid from the stuffing box. When the pump is shut down, a conventional static seal prevents pumpage from leaking. The 3175 is easily field converted to Dynamic Seal. Goulds retrofit kit includes repeller, stuffing box cover, repeller plate, shaft sleeve and choice of static sealing arrangement.
External Impeller Adjustment
Impeller clearance can be easily reset by external adjust-ment to maintain hydraulic performance. Delivers long term energy savings, while downtime is kept to a minimum.
Fully Open Impeller for Goulds 3175
Special warped vane, heavy duty open type for paper stock handling. Back pump-out vanes reduce stuffing box pressure, and help prevent solids from entering sealing chamber.
Renewable Wear Parts
Low maintenance costs because all wear parts…suction sideplate, impeller, stuffing box cover, shaft sleeve and throat bushing…are easily replaced
Standard Labyrinth Oil Seals
Inpro VBXX labyrinth seals prevent contamination of lubricant for extended bearing life.
