PWA Low Flow ANSI Process Pumps

About PWA Low Flow ANSI Process Pumps

The Model PWA-LF is an ANSI-compliant low flow horizontal process pump. It offers multiple seal chambers for maximum sealing flexibility across various process applications and features a back pull-out design for easy maintenance. Additional specifications include test flows up to 7,500 GPM, discharge test pressures up to 740 PSI, and a supply tank rated from full vacuum to 65 PSI. The pump operates at 460 volts with power up to 500 HP at 3600 RPM and includes a variable frequency drive for precise speed control up to 500 HP at 460 volts. Its robust casing makes it suitable for a wide range of industries.

PWA-LF High-Performance Case & Impeller

Engineered for precision, the PWA-LF series optimizes performance in low-flow environments where standard pumps often fail.

Precision-Engineered Hydraulics: Our circular casing volute and precisely machined discharge channels deliver higher efficiencies and stable hydraulics, even at minimum flow rates.
Low-Vibration Open Radial Impeller: The multi-vane design reduces pulsations and vane stress, ensuring smoother operation and a longer lifespan.
Reinforced Strength: Fully shrouded vanes provide exceptional structural integrity during demanding low-flow operations.
Extended Component Life: Integrated balance holes reduce bearing thrust loads and stuffing box pressure. This dual-action design extends both bearing and seal life, minimizing your maintenance intervals.

The Competitive Advantage

5-Year Unconditional Power Frame Warranty > We believe in our engineering. That’s why every unit comes standard with an industry-leading 5-year unconditional warranty at no additional cost.
