Pentair Sta-Rite HS Series Stainless Steel 4" Submersible Pumps

Precision-engineered, high-quality, rugged Signature 2000® Stainless Steel Series Pumps deliver efficient, dependable performance even in rough, aggressive water. Heads to 1,950 feet and capacities to 65 GPM. Built to deliver long-term, trouble-free service. Floating impeller design resists sand and reduces sand locking. These pumps feature the proven SignaSeal™ staging system.

KEY FEATURES

  • SignaSeal staging system incorporates a harder-than-sand ceramic wear surface and a floating impeller design - which together literally pulverize sand and small debris. This proven feature reduces lock-ups, dry-runs, and abrasive wear.
  • Floating Stage Design is engineered to transmit forces away from the motor bearing and through the pump housing. This reduces premature wear and misalignment.
  • Fully-Enclosed Shaft Bearing creates a pressure zone that prevents sand & water from entering. Eliminates wear and misalignment.
  • Wear Ring forms a seal between impeller hub and suction cap for low friction and no unwanted recirculation of water.
  • Corrosion resistant 300 grade stainless steel discharge for durability in aggressive water.
  • Large octagon wrench area for ease of installation.
  • 50 GPM series does not include motor.

Upstaged for Higher Performance

The Signature 2000® 4" submersible pump design has been delivering dependable performance since 1990. Our floating stage design continues to handle even the most aggressive water with our SignaSeal™ system that breaks down debris and reduces locking. Now we’re going further by upstaging and adding additional features to the 4" inch submersible pumps you’ve grown to trust and rely on every day!

What Does This Mean For You?

Better Performance
With increased staging across much of our 1/2 to 1-1/2HP pumps, you'll enjoy even greater performance receiving more depth and/or more flow than before.

Beat the Competition
Our increased staging gives you an average of 20% higher performance than competitive pumps at like horsepower and rated flow. We've even developed a tool to show you how our 4" submersible pumps compare to the top competitors. Visit www.pumps.com/curveenvy.html to compare your pump!
