- Self-Venting, Top Centerline Discharge Casing with unobstructed suction prevents trapped air to maintain efficiency and flow Keyed Semi-Open, Full Vane Impeller prevents clogging in thick, pulpy applications and is less sensitive to end clearance adjustment
- Recessed impeller available for low-shear applications
- Three-Point End-Clearance Adjustment resets impeller clearance to restore performance and efficiency
- Extra Heavy-Duty, Alloy Steel Shaft minimizes problems associated with overhang, deflection and vibration
- Stainless steel available.Contoured Wearplate at the impeller suction side protects casing and prolongs pump efficiency
- “Dry-shaft” Construction, using sealed impeller nut and key driven stainless steel hook sleeve, eliminates shaft corrosion
- Optional Large Conical Seal Housing allows the seal to be installed in the liquid directly behind the impeller, eliminating the need for a separate seal water flushing source
- Optional Flow Inducer significantly improves suction performance by reducing pump NPSHR
- Optional Expeller forces fluid from the seal chamber, minimizing shaft wear
- Positioned behind the impeller, the expeller eliminates the need for costly flush water and the resulting product dilution
