Industrial Process Pumps - FRBH

Flowserve Hydraulic Institute

• Flows to 9085 m3/h (40 000 gpm)
• Heads to 100 m (325 ft)
• Pressures to 14 bar (200 psi)
• Temperatures to 150°C (300°F)

Size Range: Sizes from 50 mm (2 in) to 200 mm (8 in)

• 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
