Heavy-Duty ANSI/ASME B73.1 Process Pump
This horizontally-mounted, single-stage, overhung centrifugal process pump is engineered to the latest ANSI/ASME B73.1 standard. Designed for the most demanding industrial environments, it delivers reliable performance across chemical, petrochemical, refinery, pulp & paper, and water treatment applications. It features an advanced power frame with smart monitoring and a 5-year unconditional warranty.
Key Design Highlights
- Back pull-out construction — impeller, shaft, and bearing assembly remove as a single unit without disturbing casing or pipe connections
- Fully open impeller — threaded directly to shaft with O-ring seal; back pump-out vanes reduce seal chamber pressure and axial thrust
- Externally adjustable impeller clearance — restore peak efficiency in minutes without removing the pump from the line
- Carbon steel casing (ASTM A216 WCB) — 30% higher thermal conductivity than ductile iron; casing thickness exceeds ASME B73.1 minimums
- Precision serrated flange face — optimum gasket retention; self-venting top-centerline discharge
- 3156L stainless steel shaft — standard at no extra cost; flinger disk lubrication for improved bearing life
Power Frame — Designed for Zero Maintenance
The advanced power frame delivers exceptional reliability and uptime:
- Sealed lubrication chamber with ISOMAG™ magnetic seals (IP65 rated) — zero oil maintenance for up to 5 years
- 25% more cooling surface area compared to the previous generation
- Sloped, segregated drain isolates contaminants and extends oil life
- Flinger disk lubrication standard — 30% increase in bearing L-10 life, approximately 15°F lower operating temperatures
- Dual 1″ oil level sight glasses and magnetic drain plug for metal contaminant capture
- 5-Year Unconditional Power Frame Warranty

Seal Chamber Configurations
Three seal chamber options accommodate all major mechanical seal manufacturers:
- Standard Bore — supports component and cartridge seals for general service
- Big Bore — larger cross-section for heavy-duty cartridge seals and abrasive services
- Taper Bore — optimized flow geometry reduces seal face temperature and extends seal life
Flange Standard: Class 150# flat-face serrated (standard); Class 300# raised-face (optional)
Bearing & Lubrication Options
- Standard: Flinger disk oil lubrication — single-row deep-groove (inboard) + double-row angular-contact (outboard)
- Optional: Regreasable bearings, purge oil mist, pure oil mist, or pressurized oil lubrication
- Group 3 & 4: Paired single-row angular-contact bearings (back-to-back) for maximum thrust capacity
