Description:

SL type pumps were designed specifically for successive use in slurry type applications where a large flow at a low to medium developed head is required. The type  SL pump with its encapsulated design is similar design to the HS pump, but with a significantly reduced physical size when compared to the HS pump.

 

Advantages:

Liners -- wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) active engineered attachment mechanism to casing via threaded bolts as opposed to unreliable glue

 

Impeller --  higher efficiency rates (up to 90+ %) - pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in preventing seal contamination

 

Throat bush -- wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) - adjustable via cotters to account for wear over time and increase efficiencyShaft seal

 

Bearing assembly -- All bearings assembled with highest quality tapered roller bearings in controlled environments to prevent lubricant and housing contamination - oversized shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field.

 

Pump Casing -- Split-case design allows for ease of access and maintenance on wet end parts cast ductile iron with exterior ribbing provides increased pressure ratings and reliable service over time.

 

Frame Base -- A very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.

 

 

Three Shaft Seals Types:
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.

 

Mechanical Seal
HS series heavy duty slurry pump utilizes a leak-proof mechanical seal design which allows easy installation and replacement. Other types of mechanical seal are among options to suit the slurry pump for various pumping applications.
