If you’re facing a layout challenge where your pump must sit above the liquid source—or if you’re struggling with suction lines prone to air pockets—the PWA-SP Self-Priming Process Pump was engineered specifically for you.
Unlike standard pumps that require a complex setup to get moving, the PWA-SP simplifies your entire operation. Here is how this "all-in-one" solution changes the way you handle suction lift.
The Model PWA-SP is an ANSI-compliant horizontal self-priming process pump. It offers test flows up to 7,500 GPM and discharge test pressures up to 740 PSI. The supply tank is 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.
Eliminates the Need for "Add-Ons"
Traditionally, a "suction lift" application requires a graveyard of extra equipment: foot valves, vacuum primers, or external air separators. The PWA-SP makes these obsolete.
Integrated Priming Chamber: The priming mechanism is built directly into the casing. It automatically evacuates air from the suction line by mixing it with the liquid already in the pump, separating the air, and venting it out the discharge.
Plug-and-Play Simplicity: You save on both upfront costs and long-term maintenance because there are no external valves to clog or fail.
Built for Reliable "High Lift"
Whether you’re clearing a sump or drawing from a tank with fluctuating levels, the PWA-SP is built to perform where others lose their prime.
20-Foot Static Lift: Capable of pulling liquid up from depths as low as 20 feet.
Automatic Re-Priming: If the liquid level drops and the pump pulls in air, it doesn't just spin uselessly. As soon as the liquid returns, the PWA-SP automatically re-primes itself and gets back to work.
Engineered for Durability: Carbon Steel vs. Ductile Iron
Don’t settle for the industry standard when you can have superior protection. We provide high-strength, impact-resistant Carbon Steel liquid ends at no additional cost.
While many competitors use non-repairable ductile iron, our carbon steel casings and impellers are fully repairable. This not only improves pressure containment but significantly extends the service life of your equipment, reducing long-term replacement costs.
Customizable Flange Configurations
Precision-engineered to fit your existing infrastructure. Our units come standard with ANSI Class 150# flange pressure ratings, available in both Flat Face (FF) and Raised Face (RF) designs. We customize the arrangement to meet your exact specifications at no extra charge.
