Packing Seal
As one of the most commonly used seals for rotating shafts, the packing seal can come with low-flush or full flush arrangement which uses flushing water to prevent media from escaping the pump housing. This kind
of seal is suitable for use under all pumping conditions. In situations where corrosive solids or high temperature might be encountered, Teflon or aramid fiber is used as the packing material for the gland. For
high abrasion conditions, a ceramic shaft sleeve is available.
Centrifugal Seal - Expeller
The combination of impeller and expeller creates the pressure needed to seal against leakage. Together with the gland seal or lip seal which is used as the shut-down seal, this type of seal can handle sealing requirements for applications where full-flush gland seal is impractical due to lack of water on the site, or sealing water is allowed to enter inside the pumping chamber to dilute the slurry.
12x10ST-AHR Rubber Lined Slurry Pump is cantilevered, horizontal, centrifugal slurry pumps for handling of highly abrasive, high-density slurries and support multistage serial installation. They feature frame and cover plates made out of grey cast iron or ductile cast iron (based on the pressure requirements) with replaceable wear-resistant rubber liners, rubber impellers, 8 position discharge branch and gland or expeller type shaft seals. Additionally they are available with several drive types such as DC (direct connection), V-belt drive, gear box reducer, hydraulic couplings, VFD, SCR control, etc. They are commonly used in metallurgical, mining, coal, power, construction material and similar industries.
